Understanding Engine Mount Hardening
Explanation of engine mount hardening
Engine mount hardening refers to the process by which the rubber components of an engine mount become stiff and lose their flexibility over time. Engine mounts are designed to support the weight of the engine and reduce vibrations, but when they harden, they can no longer effectively absorb these vibrations. This can lead to various issues and symptoms in the vehicle.
There are several factors that contribute to engine mount hardening. Let’s take a closer look at each of them:
Age and Usage: Engine mounts undergo constant stress and strain due to the engine’s movements and vibrations. Over time, the rubber material can deteriorate and harden, especially in vehicles that have been driven for many years or have high mileage.
