    which engine are you working with?

    To simplify your post, do you mean : When I change the water pump do I need to change its pulley as well? Then, the answer is no, unless it's been damaged.

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.
•13

  17. Loosen clamp at water pump end of bypass hose. Slip bypass hose from water pump while removing pump from vehicle. Discard old gasket. CAUTION: Do not pry water pump at timing chain case/cover. The machined surfaces may be damaged resulting in leaks.

INSTALLATION

  1. Clean gasket mating surfaces.
  2. Using a new gasket, install water pump to engine as follows: Guide water pump nipple into bypass hose as pump is being installed. Install water pump bolts. Tighten water pump mounting bolts to 40 Nm (30 ft. lbs.) torque.
  3. Position bypass hose clamp to bypass hose.
  4. Spin water pump to be sure that pump impeller does not rub against timing chain case/cover.
  5. Install a new O-ring to the heater hose coolant return tube. Coat the new O-ring with antifreeze before installation.
  6. Install coolant return tube and its mounting bolt to engine. Be sure the slot in tube bracket is bottomed to mounting bolt. This will properly position return tube.
  7. Connect radiator lower hose to water pump.
  8. Connect heater hose and hose clamp to coolant return tube.
  9. Install water pump pulley. Tighten bolts to 27 Nm (20 ft. lbs.) torque. Place a bar or screwdriver between water pump pulley bolts to prevent pulley from rotating.
  10. Relax tension from belt tensioner. Install accessory drive belt.
  11. CAUTION: When installing the serpentine accessory drive belt, the belt must be routed correctly. If not, engine may overheat due to water pump rotating in wrong direction. Refer to Illustration above for correct belt routing. The correct belt with correct length must be used.

Fan Blower working, just not getting any cold air

The tensioner pulley is not turning??? Have you been burning up belts left and right?? Is the belt tight against the tensioner pulley?? You need to check to make sure that pulley is operating correctly. Are you getting good charge out of your altenator?? Is it hard to turn do to lack of power steering?? Have you thrown the belt multiple times?? If that pulley is not spinning there is only to causes for this. Either the pulley is froze, or there is no tension against the pulley. If the pulley is frozen you should be burning up belts often. The tensioner pulley spring is broke and not holding the proper tension. The belt might still be rotating, but the belt will not be rotating the other accessories attached like it should be. My chrysler van has a dual belt set up and yes if the tension pulley is not moving then you will be lacking the rotation need to make the ac compressor operate properly.

Need 2 replace fan belt for mazda 323f 1998

The belt runs on a number of pulleys. One of which is the bottom one, called the crankshaft pulley. This is the one rotating when engine runs, driving the other pulleys with the belt. The crankshaft pulley is not adjustable, so you need to follow the path of the belt around the other pulleys. One of these will be attached to some accessory like an alternator or a water or steering pump. If there is no independent tensioner pulley, one of these accessories will have some sort of tensioning device. Could be a slotted bracket, or a long tensioner bolt that moves the accessory up or down, thereby tightening or loosening the belt tension. When you see which one it is, loosen attaching bolts for that one, and adjust accordingly. TT
