I have 2002 pontiac grand prix. My tension belt popped I replaced. Then it popped again and once again I replaced it. This time when it poped I was told that the pulley on top was bad so I replaced that. And again the belt popped what is going on

If it a serpintine belt (meaning one belt runs everything) and it comes off on its own its time for a new belt to install new or reinstall old one . All cars have abelt routing diagram if not google your car and year asking for belt diagram. Locate tensioner usually turns with wrench ( socket or box end is best) route the belt according to dia. leave tensioner for last rotate pully with wrench to get belt over release tension on wrench thats all there is to it. But if belt keeps coming off usually indicates new belt is needed could also need tensioner pully its a good idea to replace both at the same time

Re check the belt routing.

----------This will help. Thanks.

These vehicles are known to have power steering issues. They use up fluid and at about a 100k or so the pulley itself can "sheer" right off. I would check your power steering fluid level and go from there.
Thank you,

just use the size wrench that fits on the pully to relieve tension on the belt and remove belt while takeing the tension off repeat to put new on that way you dont have to remove anything

your car is back fireing.try tune up or timeing belt jumped. get it check out soon

Yes - fairly easy..

First - study and WRITE DOWN the belt path... Draw it.. What ever it takes.. Once its off - it can be confusing to remember..

Then - on the tension pulley there is a bolt in the center.. Put a closed end wrench on it it and push real hard in the direction that would relive tension on belt (usulaly downward).. It will slide right off..

Get the new one in place of correct path and push the tension pulley again to get belt on all the way and release tension pulley and it will be tight..

Note; The tension pulley is spring loaded and keeps the belt tight..

Have a great day !

• Make sure your new belt exactly matches the old belt demensions
• Take a breaker bar or big rachet & release the tension on the automatic tensioner; very slowly
• Loop the old belt around the pulleys & fan
• Install new

I didnt have to remove my alternator, I just used a 15 mm wrench to remove the left-hand threaded bolt holding the tensioner on. hope this helps

It is not very hard. You need to turn the bolt in opposite direction while applying pressure to the back side

replace the timing belt tensioner if belt or chain still loose.
