To loosen a tension pulley on a 1991 Chrysler New Yorker, turn the nut in the center of the pulley. This will allow the pulley to slide in the cut-out groove so that the belt will loosen.
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.
Yes.
It is the smaller pulley in the center rear of the belt.
Passenger side, front, lowest pulley.
The tension on a serpentine belt is automatically set by the Idler Tension Pulley. If you find it is not correctly setting the tension, the the spring may be broken.
With a self adjusting tensioner pulley, there is no adjustment for tension.
you have to push down on the tension pulley, then you would get slack in the belt
u need to relaese tension on the tension pulley. this is usually done with a long socket wrench handle. when u release tension and remove belt you then release tension on pulley until you have routed new belt . you then move tension pulley again until you can put belt on it, then release pulley and it will automatically provide correct tension
i dont know go to the shop
On a 3.3l the water pump is driven by the serpentine belt. On a 3.0l the water pump is driven by the timing belt.
I used a breaker bar for the tension pulley to relieve the tension to remove the belt, I think there are three bolts that hold the tension pulley on, just remove them and reverse the procedure to install. Follow the diagram that is either on the inside of the hood or on the radiator cover on how to thread the belt back on the pulleys.
