GM Cadillac 1967-1989 Repair Guide



See Figures 1, 2 and 3

All models covered in this guide are equipped from the factory with a ratchet-type bumper jack. This jack was only designed to aid tire changing in emergency situations. It was NOT designed as a maintenance tool. Never get under the car when it is supported by only a jack. Always block the wheels when changing tires.

A sturdy set of jackstands (at least two) and a hydraulic floorjack of at least 11/2ton capacity are two of the best investments you can make if you are serious about maintaining your own car. The added safety and utility of a hydraulic floor jack makes this tool pay for itself many times over through the years.

Drive-on ramps are also commercially available; they raise the front end of the car up about ten to twelve inches. Make sure yours are of all-welded construction and made from strong square tubing. You must make sure the rear wheels are blocked when using ramps.

Never use concrete cinder blocks for supporting any type of vehicle. They can be extremely dangerous, as they easily break if the load is not perfectly distributed.

Regardless of the method of jacking or hoisting the car, there are only certain areas of the undercarriage and suspension you can safely use to support the vehicle. Some models are equipped with slots in the bumpers, into which the bumper jack engages for changing tires. See the accompanying illustration, and make sure that only the shaded areas are used. Also, be especially careful not to damage the catalytic converter when jacking or supporting the car.
