Step 1
Make sure no one starts the car while you work. Put the keys to the car in your pocket and disconnect the battery. Be careful to keep the positive and negative cable cords from touching one another.
-
Step 2
Wear protective clothing like gloves and goggles. Remove metal rings or jewelry, which might create a shock. Make sure you don't have any loose clothing that can catch in moving parts.
-
Step 3
Allow the engine and radiator to cool to the touch to prevent hot metal or fluid from burning you. The water in the radiator remains hot after you turn off the engine.
-
Step 4
Support the car following car safety guidelines. Even if you properly set up jacks, a car may fall off the jacks if you use too much force. Professional lifts or reinforced repair dugouts provide the safety you need to prevent the car from falling on top of you.
-
Step 5
Watch out for sharp metal pieces and tight spaces. Metal shards can penetrate gloves so inspect areas before reaching in. Thread wires through rubber grommets to protect wires from fraying on sharp edges.
-
Step 6
Use tools for the intended purpose to prevent slips and damage. Control the force on parts by pulling tools toward you when possible.
