FAQ

The engine mount is an essential component of the vehicle, responsible for absorbing engine vibrations and keeping it firmly anchored to the chassis. The frequent failure of this component can be attributed to various factors:

1. Partial replacement of mounts: a common mistake
One of the main reasons engine mounts break frequently is the partial replacement of components. When a mount becomes damaged and isn't immediately replaced, the remaining mounts must bear additional load to compensate for the loss. This overload accelerates the wear of the remaining mounts, causing them to fail within a relatively short time. Even if only one of the mounts appears damaged, the others may already be compromised and close to breaking due to the extra stress. For this reason, it is advisable to replace all mounts simultaneously, especially if the damaged mount was not promptly replaced. This practice ensures optimal system balance and prolongs the overall lifespan of the mounts, avoiding further breakages in the short term.

2. Natural wear and material fatigue
Over time, engine mounts, primarily made of rubber and/or elastomeric materials, deteriorate due to continuous stress during driving. Engine vibrations, accelerations, and decelerations lead to a natural degradation of the material. External factors, such as extreme temperatures, engine oil, ozone, or other chemicals, can accelerate this process, reducing the rubber's ability to absorb vibrations properly, leading to mount failure.

3. Aggressive driving and difficult road conditions
Aggressive driving, characterized by sudden accelerations and decelerations, subjects engine mounts to greater stress than intended. Similarly, harsh road conditions, such as potholes or uneven roads, amplify stress on the mounts, accelerating their wear and making them more vulnerable to premature failure.

4. Alignment and installation issues
Poor engine alignment or improper mount installation can cause uneven stress, leading to premature mount failure. Additionally, using low-quality mounts that do not meet OEM (Original Equipment Manufacturer) standards can significantly reduce the component's lifespan. It is crucial to use high-quality products and ensure proper installation to prevent future problems.

5. Upgraded or modified engines
If the vehicle's engine has been upgraded or modified to increase power, the original mounts may not be able to handle the increased torque and vibrations, leading to premature failure. In such cases, it is recommended to use reinforced mounts designed to handle the new stresses.

6. Quality of the replaced mount: a crucial aspect
In recent years, the market has been flooded with cheap products, often from unscrupulous manufacturers, that do not meet the required quality standards. These mounts, although aesthetically similar to the originals, lack the technology and materials necessary to ensure the same level of comfort and safety. Engine mount technology has advanced significantly, with many latest-generation models featuring advanced characteristics such as hydraulic damping and, in some cases, electric sensors that regulate the damping function according to driving conditions. To avoid performance issues and ensure maximum reliability, it is essential to choose high-quality mounts, preferably produced by companies known for their commitment to quality and driver safety.

7. Design flaws in specific car models
Some car models, which until a few years ago represented a significant part of the European vehicle fleet, had design flaws in the engine suspension system and related mounts. Unfortunately, even some newer vehicles continue to suffer from the same issue, where despite using original engine mounts, they tend to fail prematurely, often within just 3-6 months of installation. Despite various attempts at modification and improvement, the structural defect of the entire system has made it difficult to extend the lifespan of these mounts, and many owners of these vehicles have had to deal with frequent replacements without finding a definitive solution to this day.

Conclusion
To ensure the durability and effectiveness of the engine mounting system, it is essential not only to replace all mounts simultaneously but also to select high-quality components and rely on experienced installers. This approach not only prevents future failures but also ensures that the engine remains stable, maintaining the vehicle's comfort and safety at the highest levels.

The expansion tank is a crucial component of the engine's cooling system, designed to manage the variations in coolant volume caused by temperature fluctuations. The rupture of the expansion tank is a relatively common issue and can arise from various causes:

1. Aging and material deterioration
Most expansion tanks are made of plastic, a material that can become brittle over time due to repeated thermal cycles and the chemical agents present in the coolant. Over the years, the plastic can develop micro-cracks that, under pressure or high temperatures, can turn into larger cracks or even cause the tank to rupture.

2. Engine overheating
An engine that frequently overheats puts the entire cooling system, including the expansion tank, under pressure. When the coolant temperature rises above normal levels, the pressure inside the system increases. If the tank cannot handle this pressure due to a faulty cap valve or general wear, it can fail, leading to rupture.

3. Problems with the tank cap
The expansion tank cap plays a vital role: its integrated pressure valve allows the system to release excess pressure. If the valve malfunctions or gets stuck, the pressure inside the tank can become excessive, causing the component to break. A defective cap can also prevent the proper return of coolant from the circuit to the tank, creating a vacuum that can damage the tank's structure. It's crucial to choose high-quality caps to ensure the entire cooling system operates correctly.

4. Coolant contamination
Using low-quality or contaminated coolant can accelerate internal corrosion in the cooling system, including the expansion tank. Chemical residues or impurities in the coolant can attack the tank's plastic, weakening it over time and making it more prone to breaking. Once again, choosing a quality coolant is essential to prevent damage.

5. Improper installation and maintenance
An improperly installed expansion tank, with bent or poorly connected pipes, can suffer additional mechanical stress, leading to rupture. Additionally, inadequate maintenance of the cooling system, such as failing to check levels or delaying coolant replacement, can contribute to the tank's deterioration. Therefore, it is crucial to ensure that the installation is done correctly and that maintenance is performed regularly to ensure the system's longevity.

Conclusion
The quality of components is crucial for the longevity of the engine's cooling system. Not only is it important to choose an expansion tank made of durable materials, but the cap must also be of high quality to ensure that the pressure inside the system is always managed correctly. Proper installation and regular maintenance complete the best approach to avoiding problems and ensuring optimal vehicle performance. To ensure the maximum reliability of the cooling system, some brands like UNIGOM prefer to sell expansion tanks already equipped with the corresponding caps. This choice is motivated by the need to ensure that all critical components of the system are perfectly compatible and of high quality, reducing the risk of problems due to defective or unsuitable caps. By offering a complete kit, these brands ensure that customers can rely on an optimal and long-lasting solution for their vehicle's cooling system.

The strut mount can break for various reasons, and pinpointing the exact cause is not always straightforward. First and foremost, it's important to remember that the strut mount is just one of many components in the suspension system, all working together to ensure the vehicle's comfort and stability. Therefore, a strut mount failure could result from issues with other connected components, such as the strut itself, the strut bearing, or the bump stop.

1. Incorrect installation of the strut or connected components: An incorrect installation of the strut can cause excessive stress on the mount, leading to its failure. Many automakers provide specific installation instructions for suspension components on their official platforms, as proper installation can vary not only between different models but also among different manufacturers. An improperly mounted bearing or an unswapped bump stop can contribute to abnormal and premature wear of the mount.

2. Low-quality struts and non-oe compliant parts: Another critical factor is the use of low-quality struts. In recent years, there has been a surge of inexpensive struts imported from Asian countries. Not all of these products meet OE (Original Equipment) specifications, which are the standards required by the vehicle manufacturer to ensure optimal performance and maximum safety. A non-compliant strut may have different stiffness and response characteristics than a high-quality OE component, applying unexpected pressures on the mounts and causing premature failure.

3. Other stress factors on the mount: Failure to replace the bump stop, which is designed to limit the strut's travel and absorb some of the stress, can also overload the mount. Additionally, a worn or damaged strut bearing will prevent proper movement of the strut, causing further stress.

4. Natural wear and exposure to the elements: Strut mounts, primarily made of rubber and metal, are subject to natural wear due to continuous stress during driving, especially on rough roads. The rubber tends to harden and crack over time, especially when exposed to harsh weather conditions like rain, snow, and road salt. Metal components, on the other hand, can rust, compromising the mount's structure.

5. Driving style and road conditions: Another common cause of strut mount failure is related to driving style, particularly when encountering rough roads, potholes, or speed bumps at high speeds. Many drivers, believing that the vehicle's suspension system can fully absorb these impacts, fail to avoid road irregularities. This behavior is dangerous because, although the impact may seem cushioned by the quality of the entire suspension system, the stress on the components, especially the strut mounts, is significant. Continuously facing these road conditions without reducing speed subjects the mounts to excessive loads, accelerating rubber wear and deforming the metal. Over time, this constant stress can lead to micro-failures and, eventually, complete mount breakage. It's important to note that a continuously stressed suspension system can compromise road holding and vehicle stability, jeopardizing safety. Therefore, it's always essential to adopt a more careful and mindful driving style, slowing down when encountering potholes, speed bumps, or uneven roads, both to preserve the integrity of the strut mounts and to ensure the overall longevity of the suspension system.

In summary, to prevent strut mount failure, it's crucial to ensure that all suspension components are installed correctly, using high-quality struts and parts that meet OE specifications. Additionally, it's advisable to rely on experienced and specialized installers who can identify the most suitable product for your vehicle, avoiding the use of inexpensive components of questionable origin that could compromise safety and driving comfort.

1. Origin and production: the reality of OEM Parts
Automakers do not directly produce most of the components in their vehicles but rely on specialized suppliers known as OEMs (Original Equipment Manufacturers). Companies like Ate, Bosch, Brembo, Denso, Luk, Mann, Valeo, Schaeffler, and others are examples of OEM suppliers that manufacture components according to the specifications required by car manufacturers. These suppliers often have production facilities in countries like China or India, but it is important to emphasize that even in these locations, components destined for original equipment must meet the same stringent global quality standards. Therefore, an OEM part produced in Asia can offer the same quality and reliability as one produced in Europe or America.

2. Quality and reliability: the crucial role of mechanical workshops
Despite advertising campaigns promoting the quality of aftermarket parts, the true test of their effectiveness lies in the daily experience of mechanical workshops. These professionals, who regularly install and handle components, are uniquely positioned to assess the actual quality and reliability of parts. Workshops can identify which brands maintain high-quality standards and which, despite the advertising, do not offer the same reliability. This assessment is crucial as it helps avoid parts that may require frequent replacements or fail to deliver the necessary performance.

3. Price and perception of quality: a lesson from experience
A high price does not always equate to quality. In some cases, inexpensive components are sold at inflated prices to create the illusion of a superior product, and only the practical experience of workshops can confirm whether a part is truly reliable. It is therefore essential not to be misled by price and to always consider the direct experience of industry professionals, who can recommend the best brands and products based on their long-term reliability.

4. Online purchases: beware of manipulation of product information
With the rise in online sales, it has become common for many motorists to purchase parts on e-commerce platforms. However, there is a risk associated with this channel: product information can be manipulated by the sites themselves, which may favor certain brands over others to maximize their profit margins. Often, the most promoted brands are completely unknown and are sometimes owned by the creators of the e-commerce sites themselves, raising questions about their actual quality. In this context, it is advisable to rely on Italian websites or those that clearly display a physical address of a parts store. This offers greater assurance of professionalism and after-sales service, which are essential when purchasing a crucial component for your vehicle.
 
Relying on experience and proven quality

We aim to provide a comprehensive answer to all questions regarding the management, diagnosis, and replacement of turbo hoses, ensuring that you can keep your vehicle's turbo system in perfect condition.

Symptoms of Damaged Turbo Hoses
Timely recognition of the signs of a damaged turbo hose is crucial to preventing more severe damage. Here are some symptoms that may indicate a problem:

• Loss of Power: A significant reduction in engine power or difficulty in acceleration could suggest that the hoses are not maintaining adequate pressure in the turbo system.
• Unusual Noises: A hissing or whistling sound during acceleration is often a sign of compressed air escaping through a damaged hose.
• Abnormal Exhaust Smoke: An increase in exhaust smoke, especially if blue or grayish, can indicate leaks or issues within the turbo system.
• Engine Warning Lights: The illumination of the check engine light may be related to air pressure anomalies caused by compromised hoses.

Causes of Turbo Hose Failure
Turbo hoses can fail for several reasons, each requiring accurate diagnosis and specific intervention: 

• Overpressure in the System: A turbocharger malfunction can cause a sudden overpressure known as “overboost.” Overboost occurs when the turbocharger generates more pressure than the system is designed to handle, causing significant stress on components like the turbo hoses, which can lead to cracks or tears.
• Overheating: The turbo system operates at high temperatures, and prolonged exposure to heat can degrade the hose material. This weakening can lead to ruptures, especially in areas where the heat is most intense.
• Engine Vibrations and Movements:Continuous engine vibrations and movements, combined with thermal expansion and contraction, can cause microfractures in the hose material. These microfractures can evolve into tears, compromising the integrity of the system.
• Debris and Dust: The presence of dust and debris inside the hoses, often due to an inefficient filtering system or a turbo failure, can cause internal abrasions that damage the material, leading to tears.
• Poor Quality Materials: Using low-quality hoses that do not meet OEM standards is a significant factor. These hoses may lack proper reinforcement or thermal resistance, causing premature failure.
• Improper Installation: Incorrect installation, with hose clamps that are too tight or too loose, can cause localized stress on the hoses. This stress can lead to cracks or tears over time.

What to Do if the Turbo Hoses Break
Diagnosis and Inspection:

• Visual Inspection: Carefully examine the hoses for cracks, tears, or signs of wear. Also, check for the presence of oil inside the hoses, which could indicate a leak in the boost system.

Hose Replacement:

• Removal and Installation: Remove the damaged hoses and replace them with high-quality new components. It is essential to replace all hoses if a turbo failure has occurred, as the malfunction may have damaged all hoses, creating micro-holes that compromise their functionality.
• System Cleaning: During the replacement, ensure that the entire boost system is free of any debris and dust. This operation is crucial to prevent further damage and ensure that the new hoses operate under optimal conditions.

Quality of Turbo Hoses, Materials, and Reinforcements:

• Aramid Fiber: High-quality hoses, such as those produced by leading companies like Unigom, use aramid fiber reinforcements, such as Kevlar, to ensure greater resistance to tension and high temperatures.
• Silicone Rubber: Hoses should be made with advanced silicone rubber, such as VMQ (Vinyl-Methyl Quality) for the exterior and FVMQ (Fluoro Vinyl-Methyl Quality) for the interior. This ensures superior resistance to oils and hydrocarbons, reducing the risk of material degradation due to exposure to aggressive chemicals.

Quality of Specific Hose Clamps for Turbo Hoses:

• Design and Materials: Hose clamps for turbo hoses are not common garden clamps; they are designed to withstand high pressures and temperatures, made of high-quality stainless steel, and equipped with precise tightening mechanisms to ensure a secure and durable seal.

Presence of Oil in Turbo Hoses: Causes and Implications

• Infiltration from the Lubrication System: The presence of oil inside the hoses is often due to infiltration from the turbocharger's lubrication system. Worn seals or damaged bearings can cause these leaks, allowing oil to enter the boost system.
• Condensation of Oil and Compressed Air: Compressed air passing through the turbo system may contain traces of oil that condense inside the hoses. This condensation can accumulate over time, creating an oil film that reduces system efficiency and can compromise hose integrity.
• Effects of Oil on Hoses: Oil can cause progressive degradation of the hose material, especially if the hoses are not designed to resist hydrocarbons. This degradation makes the hoses more fragile and prone to rupture, making it essential to identify and correct the cause of the oil leak promptly.

Conclusion
Managing turbo hoses requires attention and thorough knowledge. The symptoms of damaged hoses must be detected and addressed quickly to avoid more severe damage to the turbo system. It is crucial to understand the causes of hose failure and ensure that only high-quality components are used during replacement.

Brake hoses are one of the most critical components of a vehicle's braking system, as they are responsible for transferring brake fluid from the master cylinders to the calipers or drums, allowing the vehicle to slow down and stop safely.
Despite their importance, brake hose replacement is often overlooked, both by motorists and a significant portion of installers. However, maintaining brake hoses in perfect condition is essential to ensuring road safety and preventing potentially disastrous failures.

When to replace brake hoses:

1. Visible signs of wear: Brake hoses should be regularly inspected for signs of wear, such as cracks, bulges, abrasion marks, or fluid leaks. If these issues are detected, it is necessary to proceed with their replacement immediately. Ignoring these signs can lead to a sudden loss of pressure in the braking system, with serious consequences.
2. Aging: Even in the absence of visible damage, brake hoses should be replaced every 5-7 years. The rubber, which makes up the main part of the hoses, tends to degrade over time due to exposure to heat, cold, moisture, and chemicals. This degradation may not be visible externally but reduces the effectiveness of the hoses, increasing the risk of failure.
3. Spongy brake feel: If the brake pedal becomes spongy or less responsive, it is likely that the hoses are losing pressure due to micro-cracks or internal bulging. This sensation is a warning sign that requires immediate inspection and, if necessary, replacement of the brake hoses.
4. Replacement during other maintenance: It is good practice to replace brake hoses during major brake system work, such as replacing discs and pads. If the hoses have already been in service for several years, it is wise to replace them simultaneously with other parts of the braking system to ensure that the entire system operates at its best.

Why it is important to replace brake hoses:

1. Safety: Safety is the main reason why brake hoses must be kept in optimal condition. A damaged or deteriorated brake hose can cause a loss of pressure in the system, seriously compromising the vehicle's braking ability. In emergency situations, this can make the difference between avoiding an accident and experiencing one.
2. Preventing sudden failures: Even if brake hoses appear to be in good condition externally, internal wear can progress to the point of causing a sudden rupture. This event can lead to a total loss of brakes while driving, an extremely dangerous situation that must be prevented through careful and preventive maintenance.
3. Quality of materials: It is important to choose high-quality brake hoses, manufactured according to the standards required by car manufacturers. The use of inferior materials can significantly reduce the lifespan and effectiveness of brake hoses, increasing the risk of failure. A superior-quality brake hose offers better resistance to high pressures, temperature variations, and exposure to chemicals, ensuring safe and reliable operation over time.

Conclusion
The replacement of brake hoses is a crucial aspect of vehicle maintenance that should never be overlooked. As hoses age, they deteriorate even if they do not show visible signs of damage externally. To ensure maximum road safety, it is essential to regularly inspect brake hoses, replace them when necessary, and use only high-quality components. An efficient braking system is key to safe driving, and timely replacement of brake hoses is a fundamental part of this safety.

Brake fluid replacement is essential maintenance to ensure the safety and efficiency of a vehicle's braking system. Despite its importance, it is often overlooked by both drivers and many installers, risking the vehicle's braking capacity over time. Let's examine in detail when and why it is crucial to replace brake fluid.

When to replace the brake fluid:

1. Time Intervals: In general, brake fluid should be replaced every two years, regardless of mileage. This interval is recommended by most vehicle and brake component manufacturers because brake fluid tends to absorb moisture from the environment over time, becoming less efficient.
2. Severe conditions: In cases of intense vehicle use, such as mountain driving, city driving with frequent braking, or in particularly humid climates, it is advisable to reduce the replacement interval to a maximum of 1-2 years.
3. Mileage Intervals: Another reference parameter is mileage. Generally, brake fluid should be replaced every 30,000 - 40,000 kilometers. If the two-year usage period is reached before this mileage, it is still advisable to proceed with replacement.
4. Periodic Checks:  During periodic checks, brake fluid can be tested to verify its boiling point and the level of water contamination. If the boiling point is significantly reduced or the fluid shows a high water content, replacement is necessary, even if the time or mileage interval has not yet been reached.

Why it is important to replace brake fluid:

1. Moisture Absorption: Brake fluid is hygroscopic, meaning it tends to absorb moisture from the air over time. Even with a closed system, traces of moisture can penetrate the fluid, reducing its boiling point. Moisture-contaminated brake fluid is less effective and can cause vapor bubbles to form during heavy braking, a phenomenon known as "vapor lock," which can drastically reduce braking capacity.
2. Chemical Degradation: Over time, brake fluid can chemically degrade, losing its lubricating and protective properties. This can cause internal corrosion of braking system components such as calipers, cylinders, and brake lines, increasing the risk of mechanical failures and fluid leaks.
3. Maintaining Safety: Fresh, uncontaminated brake fluid ensures that the braking system operates at peak performance. This is especially important in emergency situations where timely and effective braking can make the difference between avoiding an accident or experiencing one.
4. Preventing Sudden Failures: Regularly replacing brake fluid prevents the buildup of impurities and internal wear, reducing the risk of sudden failures. A properly maintained braking system is less susceptible to problems such as fluid leaks, air bubbles in the circuit, or corrosion of internal components.

Brake fluid replacement is a fundamental aspect of preventive vehicle maintenance. We recommend performing this operation every two years or every 30,000 - 40,000 kilometers to maintain the braking system's effectiveness and safety. Regular attention to this aspect, combined with the use of high-quality components, will ensure that the vehicle is always ready to respond promptly and safely to braking demands, protecting both the driver and the vehicle's occupants.

Suspension arms are crucial components of a vehicle's suspension system, significantly contributing to the vehicle's stability, driving comfort, and overall safety.

This trend has reduced the availability of high-quality replacements, increasing the risk of purchasing less reliable products.

2. Influence of Driving and Road Conditions

• Driving Behavior and Road Impacts: Another critical factor in the failure of suspension arms, particularly the right one, is the driver's driving style and attention. In European countries, where driving is on the right, the right suspension arm is more exposed to stress because it is often more difficult for the driver to avoid potholes, manholes, or other road irregularities on the vehicle's right side. While the left side, visible directly to the driver, is managed with more care, the right side is more prone to "space misjudgments." These repeated impacts can cause damage to the suspension arm, leading to micro-cracks and accelerated wear, ultimately resulting in component failure.
• Road Conditions: Uneven roads, with potholes or bumps, put a strain on the suspension system. Although the vehicle is designed to cushion road roughness, the suspension components, particularly the arms, absorb a significant portion of the stress. This phenomenon is particularly critical on the vehicle's right side, which is more exposed to these irregularities.

4. The Crucial Role of Bushings and Ball Joints

• Bushing: The bushing is a vital element for the proper functioning of the suspension arm, as it absorbs vibrations and allows the arm to move in a controlled manner. When the bushing is made from poor-quality materials or does not meet OEM standards, its ability to absorb stress drastically decreases, causing rapid and premature wear of the suspension arm. Specific tests have shown that the bushing's quality is directly correlated with the arm's overall lifespan.
• Ball Joint: The ball joint, which allows the suspension arm to move smoothly, is another critical point. If this component is not made from high-quality materials and is not adequately protected from corrosion, it can develop play and deteriorate quickly, compromising the vehicle's safety.

5. Importance of Product Choice and Professional Advice

• Relying on Quality Products: Given the wide range of products available on the market, it is essential to rely on the expertise of your trusted mechanic, who can recommend the most reliable and suitable brands for your vehicle. In a market where many brands sell components without directly producing them, the mechanic's expertise is crucial to ensure the purchase of spare parts that offer safety and durability.
• Installer Mechanic's Advice: The experienced mechanic not only suggests the most reliable brands but also performs correct installation, which is essential for the component's longevity. A high-quality suspension arm, if properly installed, can prevent numerous problems and ensure safe and reliable operation of the suspension system.

The failure of suspension arms, especially the right one, is often the result of a combination of factors related to material quality, road conditions, and driving style. To ensure the safety and longevity of the suspension system, it is essential to choose high-quality suspension arms, manufactured according to OEM standards, and to adopt a driving style attentive to road conditions. Relying on qualified mechanics for the selection and installation of components is a crucial step to avoid future problems and keep the vehicle in optimal condition.
