Automatic belt tensioner - if not enough pressure replace tensioner Belt has streched too big, and the Automatic belt tensioner is at its limit. The tentioner is how yo remove the belt, so you should feel its tention with your wrench.
its above the serpentine belt on the lefth hand side of the engine
The zd30 has a hydraulic tensioner using an idler pulley to automatically tension the serpentine belt.
What causes a 1998 Pontiac transport to run hot and engine shuts off
3400 v6
tension pulley is an automatic tensioner that keeps the serpentine belt at the proper tension it is a single pulley that is smooth (no grooves) usually turning clockwise with constant pressure loosens pulley for belt removal use caution pulley is spring loaded
Front of engine (behind serpentine belt).
When my 1994 Pontiac Transport is in park and idling the the speedometer runs erratically? Why?
If it is a drive belt and not a serpentine belt is has no tensioner. You manually adjust the tension by normally adjusting tension by moving the alternator. Loosen to bolts holding the alternator in place and then adjust the tension. Tighten the bolts when the tension is right. If it is serpentine belt if you follow the belt around the the engine you will see the tensioner.
Absoultly not.
Assuming you have a serpentine belt on that 3.3L engine, the tension on the alternator would be controlled by the idler (tension) pulley. The alternator is stationary.
It is located on the engine block where the upper radiator hose connects to the engine. To get at it you need to remove the serpentine belt and alternator.
The serpentine belt can be removed by using a rachet/socket and turning the spring loaded tension pulley clockwise. Reverse the order to install the new one. (The pulley should be somewhere in the top/middle section of the drive area.
