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. Due to the small
clearance between the oil pan and the oil pump screen, jacking against the
oil pan may cause the pan to be bent against the pump screen. This will result
in a damaged oil pickup unit.
- Measure the engine movement at the engine mount in order to check
for damage to the rubber portions of the mount.
1.1. | Apply the park brake. |
1.3. | Firmly apply and hold the primary brakes. |
1.4. | Have an assistant stand to the side of the vehicle in order to
observe for engine movement. |
1.5. | Slightly load the engine, shifting from drive to reverse a few
times |
1.6. | If the engine moves more than 24 mm (0.945 in) from
the at rest position, in either direction, check for loose engine mount bolts. |
- If the engine mount bolt torque is within specifications, check
the condition of the engine mount.
- Replace the engine mount if any of the following conditions exist:
• | Heat check cracks cover the rubber cushion surface. |
• | The rubber cushion is separated from the metal plate of the mount. |
• | There is a split through the rubber cushion. |
