Step 1
Refer to the pulley and belt configuration chart that every vehicle has. This chart is very important because the configuration varies widely between vehicles. The only way to find out how to release the automatic tensioner, also called a surf belt tensioner, is by looking at the diagram. The chart is usually on the underside of the hood or one side of the vehicle's inner fenders.
-
Step 2
Find out what size driver you'll need to release the belt tension so that you can remove the vehicle's serpentine belt.
-
Step 3
Locate the operating lug for the serpentine belt tensioner.
-
Step 4
Push the lug until it bottoms down. You may need to rotate clockwise or counter-clockwise, depending on the pulley and belt configuration chart.
-
Step 5
Remove the belt from the alternator pulley.
