Step-by-Step Guide to Replace the Serpentine Belt
Follow these steps to replace the serpentine belt on your 2006 Pontiac Grand Prix 3.8:
- Locate the serpentine belt routing diagram under the hood of your car. It should be on the front of the engine or on the radiator support.
- Find the tensioner pulley. It should be clearly marked on the routing diagram. Use the ratchet to rotate the tensioner pulley in the direction indicated by the routing diagram. This will release the tension on the serpentine belt.
- While holding the tensioner pulley in place, take the old serpentine belt off and route the new serpentine belt according to the routing diagram. Make sure the new serpentine belt is properly aligned and seated into the grooves of all pulleys.
- Release the tensioner pulley and ensure that the serpentine belt is properly tensioned. You should be able to deflect the belt with your fingers about 1/4 inch to 1/2 inch. It's important not to overtighten the belt, as this can cause damage to the components it powers.
- Turn the engine on and visually inspect the new serpentine belt to ensure it is aligned properly and running smoothly over all pulleys.
