How Do I Replace the Motor Mount in a 97 Chevy Lumina?by Jamie Ratliff
The 1997 Chevy Lumina features two motor mounts that connect the engine to the chassis. The motor mounts contain rubber insulators that prevent the vibrations of the engine from transferring to the chassis and having a negative effect on the suspension system. The motor mounts also hold the engine in place to prevent it from moving too far in any direction. Motor mounts are susceptible to damage including broken bolts, separation of rubber from the mounts and cracks in the rubber insulators. If damage occurs to a motor mount, it should be replaced immediately.
Disconnect the negative battery cable with an adjustable wrench.
Raise the front of the vehicle with a jack and secure it with the jack stands.
Raise the engine slightly with an engine hoist. Alternatively, use a jack under the oil pan with a block of wood to raise the engine.
Unbolt the mounting bolts that attach to the engine with a socket wrench. Raise the engine a little more to reach the motor mount bolts that attach to the frame and remove them with a socket wrench.
Install the new motor mount. Apply thread-locking compound to all the motor mount bolts. Install the bolts that attach the mount to the frame. Tighten with a socket wrench. Lower the engine until it sits securely on the mount. Install the remaining bolts using a socket wrench and tighten securely.
Remove the engine hoist or jack and raise the vehicle to remove the jack stands. Lower the vehicle and connect the negative battery cable with an adjustable wrench.
