| • | 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 the 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 completed, make a final check to be sure service was done properly and the problem was corrected. |
