What it does
Worn mounts cause clunks when shifting, extra vibration at idle and engine movement under load. Using the correct part for your exact engine keeps oil pressure, sealing and timing where the engine was designed to run, and doing related parts at the same time saves taking it apart twice.
Installation & tips
- Support the engine from below before removing a mount, and tighten the bolts with the weight on the mounts.
- Transmission mount: Often worn at the same time as engine mounts.
- Put the new part next to the old one and compare the shape, mounting points and connections before you install it.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
