If this is an ac car you will need to get the correct belt and retreive a routing diagram from autzone or the manual. sometimes the pulleys are different for ac versus non ac and you may have to remove an idler to run the belt

How do I replace the Airconditioning/power steering belt on a Grand marquis, Mercury(1992)? please show me in a diagram or print somehow


Move the Grand Marquis's serpentine belt tensioner off the serpentine belt with the serpentine belt tool. Pull the belt of the remaining pulleys by hand. Take the belt out of the engine well. Wrap the new belt around the bottom portion of the crankshaft pulley. Follow the belt routing diagram to route the belt over each remaining pulley until only the tensioner remains. Move the Grand Marquis's serpentine belt tensioner aside once more and slip the belt onto the tensioner pulley.Hold the belt in place with one hand while you move the tensioner slowly back into position with the other. Here you can fine the quality AC parts http://www.1airconditioning.com/ac_compresor.htm

(1999 pontiac grand prix 3100 v6) how do I remove and replace my serpentine belt successfully?


Instructions Things You'll Need
  • 3/8-inch drive breaker bar
  • Metric socket kit
  • New serpentine belt
    • 1

      Park the Pontiac in a safe work area and open the hood.

    • 2

      Inspect the top of the black plastic cover that surrounds the fan for the serpentine belt routing diagram. This diagram has the instructions for installing the new serpentine belt around the accessory pulleys.

    • 3

      Inspect the front of the engine and locate the automatic belt tensioner. The tensioner on the 1999 Pontiac model vehicles is located between the alternator and the crankshaft pulley. The tensioner has a pulley on one end with a bolt head in the center of the pulley. Use the bolt head to rotate the tensioner.

    • 4

      Turn the tensioner counterclockwise with the breaker bar and a metric socket. Pull the belt out from under the tensioner pulley with your other hand. Then, slowly let the tensioner retract until it stops.

    • 5

      Pull the belt out of the other remaining pulleys. Then, pull the belt out of the engine bay and lay it on the ground.

    • 6

      Route the new belt around the crankshaft pulley. Then, route the new belt around the other remaining pullleys by using the serpentine belt routing diagram for instructions.

    • 7

      Rotate the tensioner pulley counterclockwise with the breaker bar and socket. Then, slide the new belt under the tensioner pulley. Slowly let the tensioner retract until it stops. The tensioner pulls all of the slack out of the belt and brings the new belt to the proper tension. Remove the breaker bar and socket from the tensioner pulley.

    • 8

      Inspect the new belt to ensure that it is seated inside of all the accessory pulleys as directed by the diagram. Then, crank the engine and allow it to run for about 15 seconds. Turn the engine off. Inspect the belt again once more to ensure that
      the belt is still around each pulley. Close the hood.

Need serpentine belt routing diagram for 1994 Dodge grand caravan


3.3L?
Looking at the engine from front (right side of the Van): Stating at the Top, Going Left to Right and Clockwise:
Over the Alternator
To under the Idle Pulley,
To Over the AC Compressor.
To the Left Side of the Water Pump.
To the Right side and Under the Crankshaft Pulley
To the Right side and Over and Down the Tensioner
To Under the Power Steering Pump
And Back up-to the Left side of the Alternator.
Advise when puting it on:
Put the Belt around everything else accept for the Alternator. After it is around all the rest of the Pulleys - Pull the belt up - tight from the Power steering Pump and the Idle Pulley to form a loop, holding the Belt close to the Altenator Pulley.
Using the 15mm wrench or belt tensioner bar - rotate the Tensioner Pulley towards the front of the Van and then place the belt over the Alternator.
Let me know if this helped or if you have additional information or questions. Feel free to contact me at FixYa.com!

How difficult is it to change the serpentine belt tension assembly on the 1995 pontiac grand am with the V6? Does the engine need to raised out of the vehicle?


the engine does not have to be raised
.you need a serpentine tool.it is a flat bar with hex cut outs for the pulley.or a shallow socket and ratchet.
the tensioner need to be slack to put on the new belt. draw a diagram of the belt routing of the old belt. the crankshaft is easier put on from the bottom.there is not alot of space and the belt has to be twisted sideways past a few pulleys.

Try this procedure.

To replace a worn belt, locate the idler or generator pulley.

0900823d8004ed45.jpg


Loosen the hold-down fastener for the idler or generator pulley.

0900823d8004ed46.jpg


Pry the idler or generator pulley inward to release the belt tension and remove the belt.

0900823d8004ed47.jpg


Match the old belt up for size with the new replacement belt.

0900823d8004ed48.jpg


Observe the belt routing diagram in the engine compartment.

0900823d8004ed49.jpg


Install the new belt over each of the drive pulleys. Often the manufacturer recommends a sequence for feeding the belt around the pulleys.

Install the belt squarely in the grooves of each pulley.

0900823d8004ed75.jpg


Before adjusting belt tension, check for proper pulley alignment. This is especially critical with serpentine belts. Measure the belt deflection in its longest span. If a belt tension gauge is available, use it and compare the tension to specifications.
If a belt is too tight, wear to bearings for the water pump, alternator, and engine crankshaft can result.
Some late-model Chrysler engines require a torque reading to be taken when tension is applied to the generator drive belt. This is especially important on the longer, multiribbed V-belts.

0900823d8004ed76.jpg


Pry the idler or generator pulley to adjust the belt to specifications.

0900823d8004ed77.jpg


Tighten the idler or generator pulley fastener.

0900823d8004ed78.jpg


Start the engine and check the belt for proper operation.

Any more questions please ask. Good luck.
