2. Using a ratchet and socket, loosen the tensioner bolt until the belt is loose enough to remove. It is also possible to purchase belt tensioner tools that grip and hold the tensioner in place while loosening and tightening it.
3. Remove the old belt from the pulleys and dispose of it. Use a belt routing diagram or carefully observe how the belt wound through the pulleys to ensure the new belt is installed in the same manner.
4. Place the new belt around the pulleys, starting at the crankshaft at the bottom of the engine and working your way upwards around the pulleys.
5. Once the belt is back on all the pulleys, tighten the tensioner bolt until the belt is snug but not overly tight.
6. Start the engine and allow it to run for a few minutes to seat the new belt. Turn the engine off.
7. Recheck the tension of the belt and adjust if necessary. The tension should be such that the belt deflects about 1/2 inch (1.25 cm) when pressed between the pulleys with moderate pressure.
