If a floor jack is used, the following precautions are recommended:
| • | Park the vehicle on level ground, block the front or rear
wheels, set the jack against the frame, raise the vehicle and support it with chassis
stands and then perform the service operation. |
| • | Before performing the service operation, disconnect the negative battery
cable in order to reduce the chance of cable damage and burning due to short circuiting. |
| • | Use a cover on the body, the seats and the floor to protect them against
damage and contamination. |
| • | Handle brake fluid and antifreeze solution with care as they can cause
paint damage. |
| • | The use of proper tools, and the recommended essential and available tools
where specified, are important for efficient and reliable performance of the service
repairs. |
| • | Use genuine General Motors parts. |
| • | Discard used cotter pins, gaskets, O-rings, oil seals, lock washers and
self-locking nuts. Prepare new ones for installation. Normal function of these parts
cannot be maintained if these parts are reused. |
| • | Keep the disassembled parts neatly in groups to facilitate proper and
smooth reassembly |
| • | Keep attaching bolts and nuts separated, as they vary in hardness and
design depending on the position of the installation. |
| • | Clean the parts before inspection or reassembly. |
| • | Also clean the oil parts, etc. Use compressed air to make certain they
are free of restrictions. |
| • | Lubricate rotating and sliding faces of parts with oil or grease before
installation. |
| • | When necessary, use a sealer on gaskets to prevent leakage. |
| • | Carefully observe all specifications for bolt and nut torques. |
| • | When service operation is complete, make a final check to be sure service
was done properly and the problem was corrected. |
