What is an Engine Mount and How Does It Work?
The engine mount is a crucial component that secures your engine to the vehicle’s frame or subframe. Engine mounts are typically made of durable rubber bonded to metal brackets, and in some vehicles, they include hydraulic fluid or electronic damping systems to further reduce vibration.
The left engine mount (driver’s side on most vehicles) absorbs engine movement and vibrations, keeping the engine stable during acceleration, braking, and cornering. This ensures a smoother, quieter ride and helps protect other drivetrain components.
Why Engine Mounts Matter
When an engine mount wears out, cracks, or breaks, it can no longer properly absorb engine vibrations. This leads to excessive noise, shaking inside the cabin, and potential damage to surrounding components such as hoses, wiring, and the exhaust system.
Replacing a faulty mount ensures your engine stays properly aligned and reduces strain on the vehicle’s structure and other mounts.
Important to Know:
- Engine mounts should be replaced as soon as signs of failure appear to avoid damage to other parts.
- It’s common to replace multiple mounts together, especially if the vehicle has high mileage.
- Hydraulic and electronic mounts cost more but provide better vibration control.
How Left Engine Mount Replacement is Done:
- Inspect engine and mounts for wear, cracks, or collapsed rubber.
- Support the engine with a hoist or jack to relieve pressure on the mount.
- Remove the worn or damaged left engine mount.
- Install a new OEM-quality mount and torque bolts to factory specifications.
- Inspect and test for proper alignment and reduced vibrations.
- Road test the vehicle to confirm smooth operation.
When to Replace Engine Mounts:
Engine mounts typically last 60,000–100,000 miles, but harsh driving, frequent stop-and-go traffic, or oil leaks can cause earlier failure.
Signs You May Need a New Engine Mount:
- Excessive engine vibration felt inside the cabin
- Clunking or banging noise during acceleration or braking
- Engine visibly shifting in the bay
- Increased noise from the engine area
- Worn or cracked rubber in the mount
