Serpentine Belt Replacement

Did a search and even went to Shoebox's page, but didnt see anything.

Never done it before, what all is needed to do the job? Do i need an impact wrench or will a simple socket do the trick? What all do I have to take off to get easy access to it?

Also what is the part number for that goodyear gatorback belt?

Thanks for the help guys.

Re: Serpentine Belt Replacement

you need a 1/2 inch wrench for the tensioner and thats it simple to do. Sorry not sure the part number..

Re: Serpentine Belt Replacement

Your parts store will be able to look up the number for you. It's a 13mm bolt head on the center of the belt tensioner pulley that you'll get use to "compress" the tensioner to remove the belt. I use a socket and a long handle ratchet. The belt routing should be on the cover plate of the radiator if you get confused.

Re: Serpentine Belt Replacement

Hows the access to this area? Anything need to be taken off to get access?

Also, may be a stupid question (and i have a feeling it is), which one is the tensioner?

You can tell I really havent done much work on this area of my car. LOL

Re: Serpentine Belt Replacement

on the diagram where it shows the pulleys (on the radiator cover) and the route of the belt there will be a smaller one on the bottom left that has an arrow showing which way the pulley swings. just get under the car, put the socket on the bolt and "tighten it," or just turn it clockwise and it will swing down, loosening the tension on the serpentine belt. just remove the belt and put the new one on, making sure you follow the correct way posted on the radiator cover. if it helps, the tensioner pully is about 3.5-4" in diameter. someone correct me if that's not the right size, i dont have one with me right now. good luck!

Re: Serpentine Belt Replacement

I guess it should be mentioned that you pretty much have to do this from underneath the car and that with the car sitting at it's normal height you can't get underneath to do it. You need to jack it up or find a curb to park on-that would probably be high enough.

Re: Serpentine Belt Replacement

one more question... is there a certain torque setting the tensioner needs to be torqued down to when putting it back together? Just wondering if i need to rent a torque wrench when im picking up the belt.

thanks all...

Re: Serpentine Belt Replacement

The tensioner shouldn't come off, just swing in so the belt can fit on. When you let off it with the ratchet the tensioner just goes back into place.

Re: Serpentine Belt Replacement

Probably take longer to jack the car up than it will to change the belt.

Re: Serpentine Belt Replacement

Actually, in the cam removal guide on my site, there is mention of removing the belt and how to do it.
