What is the typical lifespan of engine mounts?
2 Answers
With proper driving, engine mounts can last a lifetime and generally can be used for more than five years. Additional information is as follows: 1. Engine mounts, commonly known as engine mount rubbers, are wear parts with a designed lifespan typically ranging from 60,000 to 80,000 kilometers. Their main functions include: securing the engine to the frame; the rubber on the mount serves to dampen vibrations, preventing engine vibrations from being transmitted to the vehicle interior. 2. After engine mounts are damaged, the symptoms in the car are not particularly distinctive and can easily be overlooked. The main symptoms are shaking and vibrations, but there are many reasons why a car might shake. Checking and replacing engine mount rubbers is relatively straightforward.
I've been driving for over 20 years and have witnessed significant variations in engine mount lifespan. Under normal conditions, they can last 5 to 10 years without issues. With smooth roads and gentle driving, they endure longer - my old car's mounts remained good for 8 years. However, frequent rough road driving or aggressive acceleration accelerates rubber wear, potentially causing failure within 3-4 years. Neglecting worn mounts leads to worsening vibrations, tractor-like noise, and in severe cases, engine misalignment that may damage adjacent components. Always have technicians inspect for cracks or softening during routine maintenance - this crucial check prevents unsafe roadside breakdowns. Lifespan varies considerably by make: European vehicles typically have shorter mount life, while Japanese models use higher-quality, more durable rubber compounds.
