SOURCE: I need to replace a serpentine belt on a 2001 GMC

it is decieving. if the tensioner has an extension of about two inches from the base, it takes a 15 mm to lift it, be easy, make sure the wrench is not going to touch anything as you release it after taking the belt off

SOURCE: 1999 dodge durango 5.9 v8 loud squealing noise

You didn't mention the alternator, power steering pump, or water pump. In fact, any pulley other than the crankshaft one can have a bad bearing or dry seal. Remove the belt and spin each pulley while listening for any rough noise or squeal. If it was the crankshaft, it might be time to check the oil. Start the engine with the belt off to see if it does squeal. Make sure the noise isn't coming from the radiator fan(s).

My new blet wont stay tight on my 98 gmc envoy


I guess my first question would be are you sure you got the right replacement belt ? And are all of the pulleys on straight ?
Is the belt slipping, or coming off ?
Was the original belt giving you problems ?

Have a squeal and lost some antifreeze but did not over heat. I am wondering if this could be the water pump going bad are what?


Remove the belt. Then pull/push and spin the water pump pulley. If it has lots of play its likely the pump. But I've also had the idler wheel / belt intensioner pulley make noise.

2004 gmc envoy. has a 6cyl and a serp belt. the center pully off set to the left (i think its a water pump) has a bad wobble and making a horrible noise. Not over heating and no leaks. should i just change...


If the fan is attached to it than it is the water pump making the noise and it will need to be replaced. If the fan clutch is not attached to it than it is either the idler pulley or the tensioner pulley. The tensioner is on the passenger side (left) of the front of the motor.

Remove belt,center pulley, fan, and three bolts holding pump on. When tightening bolts, find out torque spec first, those little bolts will not take much.

Engine whinning


I had the same problem on my 2005 Envoy. Turned out to be the idler pulley bearing. It is just a pulley the belt rides on. The bearing in the pulley was what was making the high pitched whine. I replaced the bearing, and the noise went away.
