How Many Years Do Engine Mounts Generally Last?
3 Answers
Engine mounts generally last for 5 years. Below is relevant information about engines: 1. Introduction: An engine is a machine capable of converting non-mechanical energy into mechanical energy. 2. Classification: Includes internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. 3. External Combustion Engine: An external combustion engine means the fuel burns outside the engine. 4. Internal Combustion Engine: An internal combustion engine, or reciprocating piston engine, differs most from external combustion engines in that the fuel burns inside it. There are many types of internal combustion engines, with common gasoline and diesel engines being typical examples.
There's really no fixed lifespan for engine mounts. After over a decade of car ownership, I've found there are many influencing factors. My old Nissan Sylphy needed its first engine mount replacement at 6 years, while a friend's city commuter car lasted 9 years. The key is the rubber deterioration - my frequent rural road driving with heavy chassis vibration accelerated wear. Last time at the repair shop, I saw cracked mount rubber that had crumbled to pieces. The mechanic said continuing to drive in that condition would shake the engine apart. I recommend checking every 50,000 km. If the steering wheel shakes noticeably at idle or you hear loud thumping from the engine bay over speed bumps, it's time for replacement. With normal use, they typically last 5-8 years without issues.
As someone who has owned three cars, I consider engine mounts more like consumables than permanent fixtures. The original mounts on my American car lasted only three years, while the aftermarket replacements I installed later held up for six years. Weather plays a significant role – in northern winters at -20°C, the rubber becomes rock-hard, while in summer it turns soft and saggy. This thermal expansion and contraction really shortens their lifespan. During routine maintenance, always check if the mounting bolts are loose. Cheap aftermarket mounts often deform within six months. The newer hydraulic mounts are more durable, but they cost three times as much. All things considered, I'd recommend replacing rubber mounts around 80,000 kilometers for optimal value.
