Checking and replacing the engine mount (Chevrolet Lumina 1)

Attention! When performing the procedures discussed below, it is recommended to use appropriate techniques and devices. Be careful not to get under the engine when it is raised on the jack. Jack failure can result in serious injury or even death.

1. Engine mounts are generally maintenance-free, but if they become damaged or broken, they must be replaced immediately, otherwise the additional load on the transmission may cause damage or premature wear.

Examination

2. During the inspection, the engine should be slightly raised so that the supports are unloaded.

3. Raise the vehicle and securely support it on stands. Place a block of wood between the jack base and the oil pan, then carefully lift the engine just enough to take the weight off the jack mounts.

4. Check the bearings for defects such as hardening, cracking and peeling of the rubber from the metal plates. Sometimes the cracking occurs right in the center of the rubber element.

5. Check for movement of the support plates and the engine or frame (using a large screwdriver as a lever, push down on the rod to see if the support will move). If movement is detected, lower the engine and tighten the mount fasteners.

6. To increase the service life of the supports, put protective rubber covers on them.

Replacement

7. After disconnecting the negative battery cable, lift the vehicle and support it securely on stands.

8. Remove the engine shock absorber (see illustration 4.4).

9. Raise the engine slightly with a jack or lift. Loosen the bolts and separate the support from the frame (see illustration).





10. After unscrewing the bolts (nuts) securing the support bracket to the cylinder block, remove the support.

11. The support is installed in the reverse order. Apply a coat of sealant to all fasteners and tighten them securely.
