    Q:
    How do you inspect the front Engine Mount for the 1989 Oldsmobile Cutlass? Posted by Baris Y.
    A:
    To inspect the front mount, raise the engine slightly to create tension on the rubber mount using a hoist or jack placed under the forward edge of the oil pan. Check for heat cracks on the hard rubber surface, rubber separating from the metal plate, or splits through the center. You can Select Your Vehicle to see complete installation and repair tips.
