Engine Mount Inspection

WARNING: This page is about a different car, the 2002 Pontiac Firebird and 2002 Chevrolet Camaro. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Broken or deteriorated mounts can cause misalignment and destruction of certain drive train components. When a single mount breaks, the remaining mounts are subjected to abnormally high stresses.

NOTE: When raising or supporting the engine for any reason, DO NOT use a jack under the oil pan, any sheet metal, or the crankshaft pulley. Lifting the engine in an unapproved manner may cause component damage.

Measure engine movement at the engine mounts in order to check for damage to the rubber portions of the mount.
- Apply park brake.
- Start the engine.
- Firmly apply and hold primary brakes.
- Have an assistant stand to the side of vehicle in order to observe for engine movement.
- Slightly load the engine and shift from drive to reverse a few times. If engine movement is more than 0.945" (24 mm), from at rest position, in either direction, check for loose engine mount or mount bracket attachments.
If engine mount and engine mount bracket bolt torque are to specifications, check condition of the engine mount.
Replace engine mount if any of the following conditions exist:
- Heat check cracks cover the hard rubber surface.
- The rubber cushion is separated from the metal plate of the mount.
- There is a split through the rubber cushion.
