How Many Years Do Engine Mounts Generally Last?
3 Answers
Engine mounts can typically last for over 6 years under normal usage conditions, and there is no definitive replacement interval. However, they must be replaced immediately if inspection reveals signs of cracking, aging, or corrosion. Generally, engine mounts are replaced after at least 150,000 kilometers, with some vehicles requiring replacement only after 200,000 kilometers or even longer. Below are specific details about engine mounts: 1. Vibration Absorption: During engine operation, certain vibrations are generated. The rubber components in engine mounts help eliminate resonance produced by the engine. 2. Pressure Relief Function: Some engine mounts also feature hydraulic pressure relief capabilities. If the mount is damaged, engine vibrations can cause the entire vehicle body to vibrate. 3. Impact of Damage: Typically, there are three engine mounts fixed to the vehicle frame. If one is damaged and not replaced promptly, it disrupts the balance and can accelerate the wear of the other two mounts.
I've been driving for decades and have owned three cars. Engine mounts can generally last six to seven years without issues. My first car was mostly used for city commuting, and the engine mount loosened after four years, causing severe steering wheel vibrations while driving. The second car was used more for long-distance trips and lasted seven years before needing a replacement. Many factors affect their lifespan—bumpy roads or frequent hard acceleration can wear them out faster, while keeping the car in a clean garage helps prolong their use. Regular maintenance checks are essential; addressing minor issues promptly prevents engine sagging and safety risks. I recommend having a mechanic inspect them every two years—don’t wait until they fail completely. It saves hassle in the long run.
With over 20 years of car repair experience, the typical lifespan of engine mounts is five to seven years. For ordinary family cars, they may start aging after 50,000 to 60,000 kilometers, especially during cold starts in winter when vibrations increase. It varies by model: Japanese cars tend to last longer, while German cars are more precise but costlier to repair. Obvious symptoms include engine vibrations transferring into the cabin and a noticeable thumping sound. It's advisable to regularly inspect them during maintenance from the time the car is new. Replacing them costs just a few hundred dollars—don't skimp on this. If you frequently drive on bumpy roads or carry heavy loads, early inspections can extend their overall lifespan.
