I JUST HAD MINE REPLACED.THEY ARE SPRING LOADED(AUTO ADJUSTING) THE PART WAS $65.OO AND LABOR WAS ONE HOUR.
Loosen the tensioner pulley. Put the belt around the alternator pulley and the tensioner pulley. Move the tensioner pulley to the right until the belt is tight. Tighten the tensioner pulley.
How do you change the supercharger belt tensioner in 1997 Pontiac Grand Prix GTP?
You cannot adjust the belt tension on a 2000 dodge grand caravan. This vehicle is equipped with an automatic tensioner. If tensioner is frozen or will not hold the belt tight, it must be replaced.
alternator on a 2000 Pontiac runs off a serpentine belt if its loose then chances are ur serpentine belt is worn or stretched or your tensioner pulley is bad or the tensioner itself..alternator bolts stable does not move like the old setup.
It is likely that there is a tensioner (looks like a pulley but doesn't spin) that may be loose. Check to see if there is one. There should be a bolt that adjusts it to slide up and down.
what size engine
The belt tension should adjust automatically. There's a thing called a belt tensioner that has a strong spring in it (you can't see the spring) that keeps pressure applied to the belt. This belt tensioner is what makes the serpentine belt so hard to remove. Many times the tensioner is in a difficult place access.
Yes, if the belt tension is not tight enough it won't spin the radiator fan due to slippage. Replace the tensioner pulley.
on the crank pulley
Yes, on a 3.3 or 3.8 the serpentine belt pulley does come off the tensioner arm but the bolt is left thread not right handed.
When the tensioner pulley is frozen and u need to change the belt the only possible thing you can do is cut the old belt and replace the belt tensioner pulley, theres no other possible method.
The Pontiac Grand Prix has a Timing Chain with a spring loaded tensioner. The tensioner is know to wear, crack and then break. The timing chain and tensioner should be replaced at 100,000 miles. This is a pretty big job that can be done with the motor in the car. $$$ Ray
