How To Change An Alternator

Remove the Belt from the Pulley

You’ve reached the most difficult part of the project - the removal of the belt. You won’t need to remove the entire belt, but you will need to loosen the tensioner pulley enough to slip it off. Depending on the type and age of your vehicle, you may have a spring-loaded tensioner or a rod-end type tensioner. Spring-loaded tensioners can be pulled back with a wrench, whereas rod-end type tensioners require using a wrench to loosen the belt by decreasing the length of the rod.
