With a single serpentine belt most gm models have a belt tensioner which has a small square hole in the tensioner. You put a 3/8 inch drive ratchet in the hole and pull up or push down to release the tension off the belt. Once you have released the tension pull belt off of one pulley and you can ease up on ratchet and take ratchet out.

Replace alternator belt


To replace the alternator belt, you must first remove the Power Steering/Air Conditioner belt. The tensioner for this belt is on the left side of the engine (when viewing from the transmission end). Loosen the tensioner pulley center bolt and then loosen the adjusting bolt. Then the alternator bolts must be loosened and the adjusting bolt for the alternator must be loosened.
Reverse procedure after installing new belt/belts.

I replaced my belt recently and the belt is still squelling when i start it up and drive it gos away after about 15-20 minutes... my truck is a 2001 gmc denali...


THE BELT TENSIONER MAY NOT BE WORKING LIKE IT SHOULD.
ALSO, THE BATTERY MAY BE GOING DEAD WHILE YOU ARE PARKED. WHEN YOU RESTART, THERE IS A VERY LARGE LOAD ON THE ALTERNATOR AS IT TRYS TO RECHARGE THE BATTERY. CHECK BATTERY AFTER IS SITS OVER NIGHT.]

How can i remove the alternator from a 2002 gmc safari i allready remove the air filter but i dont know how to loose the band?


use a ratchet without any socket on the idler/tensioner pulley, this will loosen the tension on the belt to be able to remove it. after that, it's easier to remove the alternator with the braket still on, that bracket has a few long bolts 3-4 to remove, the, disconnect wires from alternator. installation is reverse procedure as always

How do replace the alternator belt on a kia 2002 sportage


There is a log bolt that needs to be loosened,but the bolt on the back ,top of the alternator has to be loosened first,then turn the long adjusting bolt counter clock wise,to loosen the alternator to get the belt off,after loosening the long bolt you can pull on the belt itself,and this will pull the alternator towards the engine,then you can remove the bolt.

Car squeals when i turn the wheel, and grinds. sometimes the power steering does not work at all. Just got a new alternator installed, this problem was not there before. it is a 2003 GMC ENVOY XL SLT


Check to see if the belt(s) are properly tightened. May have loosened up after the alternator changed.

Or, the P/S pump is failing. The grinding could be the bearings inside the P/S pump.

If the problem was not there before the Alternator was done, I would take it back, and ask.
