Will Not Replacing a Broken Engine Mount Affect the Car?
3 Answers
Not replacing a broken engine mount will affect the car. It can also damage the engine and pose a threat to personal safety. Function of Engine Mount: To buffer the engine's vibrations and prevent them from being directly transmitted to the car body. Material of Engine Mount: It is made of rubber, which can harden and age over time with prolonged use. Operation with Aged Engine Mount: When the engine mount ages, the vibrations caused during operation will be directly transmitted to the car body, making the vibrations clearly noticeable inside the car. Some engine mounts may even break after prolonged use, posing a significant threat to personal safety.
I've been repairing cars for over 20 years. If the engine mount is broken and you insist on not replacing it? That's like letting the engine dance! The engine vibration will transmit to the steering wheel, making your hands numb at red lights. What's even scarier is that the engine position will shift, causing damage to the driveshaft and exhaust pipe, with automatic transmissions making loud clunking noises when shifting. Last year, a BMW owner delayed repairs and ended up spending five figures on transmission repairs. If the rubber is cracked more than 1 cm, it must be replaced, especially for German cars which are particularly sensitive to vibrations. Don't save small money only to invite big trouble.
Drove my friend's car with a broken engine mount, it was like sitting on a massage chair while driving! Going over speed bumps made loud clunking noises from the chassis, and at idle during red lights, the entire rearview mirror was shaking—even the wipers were doing the robot dance. The mechanic showed me after removing it—all the hydraulic fluid had leaked out. The worst part was the AC cooling became weaker because the compressor was vibrating along with the engine. Once on the highway, the abnormal body vibration almost made me call for help—turns out it was all because of this thing. If you notice abnormal steering wheel vibrations, get it checked ASAP.
