Notice: 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.

Notice: 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.

1. Measure the engine movement at the engine mounts in order to check for damage to the rubber portions of the mount.

1.1.	Apply the park brake.

1.2.	Start the engine.

1.3.	Firmly apply the primary brakes.

1.4.	Have an assistant stand to the side of the vehicle to observe for engine movement.

1.5.	Slightly load the engine in reverse and drive. If the engine moves more than 24 mm (0.945 in) from the at rest position, in either direction, check the engine mount attachment.

2. If the engine mount attachment is within specifications, replace the engine mount.
3. Replace the engine mount also 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.

4. If the mount is loose, lower the engine and tighten the bolts or the nuts to the engine frame or the bracket. Refer to Fastener Tightening Specifications .
