How do you change a serpentine belt?

You can't change the serpentine belt. It really has to want to change.
How do you change a serpentine belt?
look for the tension pulley, it has a hex nut, that a socket and breaker bar can release the tension to let the belt slack off. You may find help to do this, as it is easier with a third hand.

Jeep or Ford/GM?



GM has an auto tensioner which when moved away from the belt (i cannot say counterclockwise or clockwise because it can change)

it will loosen the belt. usualy you can stick either a 1/2 breaker bar or a 3/8 ratchet into the provided %26quot;hole%26quot; to move the tensioner.



instalation is reverse of removal but keep in mind the routing of the belt, OR locate the belt routing diagram under the hood. some come with extra routing options when certain accesories are installed. know what you have installed before you reroute the new belt.





JEEP/chrysler (some models)these you usualy have to loosen 2-3 bolts on the power steering pump and push the pump toward the engine. keep in mind the belt routing. if you are inexperienced in the automotive area it is advised you leave the Jeeps and chryslers to an experienced person be it your neighbor kid whos wrenchin on his tuner all the way up to a dealer because belt tension settings on these are crutial.
When you go to the parts store and buy the belt get a cheap repair manual from the rack for your vehicle. Cost is about $12. It will give you easy to follow instructions with pictures and then is ready for the next repair you have to make. I am not a mechanic and don't have money to pay one and with this book, I can fix anything.
Its easy to change but hard to get at,. Look for the pulley that the top of the belt rides on it. The ribbed side will be facing up. It has a notch near the end of it where a socket wrench can fit in it but your arm might not be able to reach it. I use a solid piece of pipe and try to press down enough on the top of the pulley to gain some slack in the belt so I can pull it off from another pulley. Depending on the way your belt travels is how you determine which way to push or pull the pulley.



Good luck...
