SOURCE: How to tension a serpentine belt

It sounds like you have an auto tensioner. There is a square hole in the bracket the tensioner is mounted on. Put a breaker-bar drive or ratchet-drive (3/8 or 1/2) in that hole -- this will allow you to move the tensioner so you can get the belt around the water pump.

Installing water pump in 97 cavalier 2.2


Hi. Here's the proceudere on how to replace the water pump of your 97 Chevy Cavalier.


•1
Drain the cooling system. Place a large oil drain container under the drain fitting located on the bottom of the radiator. Turn the drain fitting counterclockwise until fluid is draining from the radiator. Use a pair of pliers to turn the drain fitting if you cannot turn it by hand. Turn the fitting clockwise to tighten it after all of the fluid has drained from the radiator.
•2
Remove the cooling fan. Disconnect the electrical connection from the fan motor. Remove the bolts holding the fan assembly to the radiator support with a ratchet wrench. Pull the fan assembly up from the engine compartment and remove it.
•3
Remove the serpentine belt. Place a wrench over the belt tensioner and rotate the tensioner to release the tension on the belt. Pull the belt off the pulleys and remove it from the vehicle.
•4
Remove the water pump pulley. Place a screwdriver behind the pulley to lock it in place while removing the pulley mounting bolts with a ratchet wrench.
•5
Disconnect the coolant hoses running to the water pump.
•6
Remove the water pump mounting bolts with a ratchet wrench or wrench and remove the water pump from the vehicle.
•7
Clean the mating surfaces of the engine block and new water pump with a towel saturated with lacquer thinner.
•8
Apply a thin layer of RTV sealer to both sides of the new water pump gasket and place the gasket on the new water pump.
•9
Place the water pump against the engine block and finger tighten the water pump mounting bolts to hold the pump in place. Tighten the bolts with a torque wrench to 18 foot-pounds.
•10
Place the pulley on the water pump and install the water pump pulley mounting bolts with a ratchet wrench.
•11
Attach any hoses previously disconnected from the water pump.
•12
Install the serpentine belt. Route the belt over the pulleys according to the routing diagram in the engine compartment. Place a wrench over the belt tensioner and rotate the tensioner to tighten the tension on the belt.

How do you tighten serpentine belt


Typically serpentine belts are tightened automatically by a tensioner, if the belt is slipping, or squealing, try installing a new belt, careful of the routing tho, be sure to install it correctly, or more problems may occur.

Installing accessory belt for 1990 cadi sedan deville


Ewww.. when the belt shredded, it may have ripped off parts, like additional tensioners. Try buying a service manual for your specific car, and look to make sure of the pathing, and components where the belt is supposed to run. It may laso have loosened other components that act as tensioners, such as A/C compressor, smog pumps, or power steering pumps. Check to see if all these are tight. If you can slide the component along the belt axis, that component will need to be pulled to tighten the belt, and then tightened down to maintain tension.

Replacing water pump on a dogge Caravan 1996


Alright, here's a pic of the mechanicals:
0900c1528006619e.jpg


The bad news is on your vechile you have to remove the timing belt, but here's a step by step.
  1. Disconnect the negative battery cable.
  2. Remove the drive belts.
  3. Drain the cooling system.
CAUTION When draining coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.
  1. Remove the timing case cover and timing belt. Refer to Timing Belt Covers and Timing Belt Removal procedures.
  2. Remove the pump assembly mounting bolts.
  3. Separate the pump assembly from water pipe and remove.
  4. Clean gasket and O-ring mounting surfaces.
  5. Install a new O-ring on water pipe and lubricate with water.
  6. Install a new gasket on pump body.
  7. Press the water pump assembly into water pipe.
  8. Install pump mounting bolts and tighten to 27 Nm (20 ft. lbs.).
  9. Install timing belt and cover. Refer to Timing Belt procedures.
  10. Install drive belts.
  11. Fill the cooling system
To remove timing:
0900c152800661ff.jpg
The timing belt can be inspected by removing the upper (front outer) timing cover.
  1. Disconnect the negative battery cable.
  2. Remove the accessory drive belts.
  3. Remove the timing belt covers.
  4. Identify the timing belt running direction to avoid reversal during installation.
  5. Loosen timing belt tensioner bolt and remove timing belt.
  6. Remove the crankshaft sprocket flange.
To install:
  1. Rotate the crankshaft sprocket until timing mark on crankshaft sprocket is lined up with the oil pump timing mark at 1 o'clock position.
  2. Rotate the (inner) camshaft sprocket until mark on (inner) camshaft sprocket is lined up with the timing mark on alternator bracket.
  3. Rotate the (outer) camshaft sprocket (radiator side) until mark on the sprocket is lined up with the timing mark on the timing belt inner cover. Refer to timing belt illustration.
  4. Install the timing belt on the crankshaft sprocket while maintaining pressure on the tensioner side.
  5. Position the timing belt over the camshaft sprocket (radiator side). Next, position the belt under the water pump pulley, then over the (inner) sprocket and finally over the tensioner.
  6. Apply rotating force in the opposite direction to the camshaft sprocket (radiator side) to create tension on the timing belt tension side.
  7. Rotate the crankshaft in a clockwise direction and recheck engine timing marks.
  8. Install the crankshaft sprocket flange.
  9. Loosen the tensioner bolt and allow tensioner spring to tension the belt.
  10. Again rotate the crankshaft in a clockwise direction (2) full turns. Recheck the engine timing. Tighten the tensioner bolt to 23 ft. lbs. (31 Nm).
  11. Install the timing covers.
  12. Install the accessory drive belts.
  13. Connect battery negative cable.
Hope this helps.
