Hi, where do I find the water pump on a holden zafira 2.2L 2004

If it's like the US spec 2.2 and I think it is, the water pump is driven by the alternator air con belt. It is small and recesses into the engine. Almost looks like just a pulley.

Air con cool for a few days then won't get cool, stop and restart all good

Cars for years have been using a serpentine belt. The compressor only works if the belt is spinning. With the engine running check to make sure the belt is spinning consistently. The alternator or the water pump could be seizing up causing the belt to stop. Check your idler as well. Tension on the belt could be loose and again not turning everything.

I have just purchased a 1998 malabu with a 3.1 engine. It has a rattle when cold. Any ideas? I've been told not to worry.

IAC (IDLE AIR CONTROL) should be replaced. You will be amazed at the difference when you change it.

Squealing,I have new belts and alternator.

Squealing is associated with belt slippage. 1) ensure that the belt is tight - at the longest distance between two pulleys it should be possible to twist the belt by about 90 degrees only. 2) with the engine running check funder the hood or the free running of the pulleys. a) Ask a colleague to engage the power steering from lock to lock and see if the power steering pump pulley does not cause slippage. b) set the air con to low and watch what happens when the compressor pump solenoid engages. If the belt begins to slip on the air con compressor pulley it is likely that the compressor is beginning to fail by seizing up. In that event preserve the belt simply switch the air con off and pray for cooler weather until the compressor can be overhauled.

While idle cuts off when air condition is on

Solution: 1. The engine has Idle Air Controller (IAC) that is suppose to keep the engine speed at a constant (even with changing load - AC, FAN, etc.) If the IAC is broken your idle will be rough or even die.
The AC compressor places a large load on your engine.If there is a problem with your IAC(Idle air controller)which is located on the throttle body it will cause the vehicle to die when you turn the AC on.Remove the IAC and check it for carbon.If there is carbon try to clean it up with a wire brush.
2. If your air con is drawing more power than your alternator/battery is capable of supplying - you could try fitting a higher charge rate alternator and a heavy duty battery also ensure battery to chassis earth is sound and clean of rust and grime at metalwork.
3.Another reason for this is that when the air con is on, ice and water forms on the outside of the air con pump and condenser. This ice and water can spray around the engine bay and if there is any electrics that are around it can cause a short circuit.The easy way to fix this is to identify the air con pump and condenser, then spay WD40 on all the electrical components you can see in the direct area.
WD40 displaces water and will cause no problems with the cars electrics.

Replacing the alternator

Fig. : Alternator mounting-2.2L engine



(2.2L Engine)
  1. Disconnect the negative battery cable.
  2. Raise and support the front of the vehicle, then remove the passenger side tire and wheel assembly for access to the rear of the alternator through the wheel well.
  3. Working through the wheel well, unfasten the alternator brace-to-block bolt, then remove the brace-to-intake nut and the brace-to-engine stud nut.
  4. Unplug the alternator wiring connector, then remove the battery terminal nut and wire.
  5. Carefully release the serpentine belt tension and remove the belt from the alternator pulley. Do not allow the tensioner to snap back into position once the belt is off the pulley.
  6. Loosen the alternator retaining bolts, then support the alternator and remove the fasteners. Remove the alternator from the vehicle.

To install:
  1. Position the alternator in the vehicle and loosely install the retaining bolts.
  2. On 1994-98 models, tighten the top alternator bolt to 22 ft. lbs. (30 Nm) and the bottom bolt to 32 ft. lbs. (43 Nm).
  3. On 1999-99 models, tighten the rear bolt to 37 ft. lbs. (50 Nm) and the front bolt to 18 ft. lbs. (25 Nm).
  4. On 1994-98 models, install the alternator brace, then tighten the retaining nut(s) and bolts to 22 ft. lbs. (30 Nm).
  5. On 1999-99 models, install the alternator brace, tighten the brace-to-alternator and brace-to-intake retainers to 18 ft. lbs. (25 Nm). Tighten the brace-to-engine stud nut to 37 ft. lbs. (50 Nm).
  6. Install the battery terminal wire and tighten the retaining nut, then engage the alternator wiring connector.
  7. Hold the serpentine drive belt tensioner, back off the belt while slipping the belt over the alternator pulley. Gradually lower the tensioner into contact with the belt, then check for proper alignment and tension.
  8. Connect the negative battery cable.

Fig. : Alternator mounting-4.3L engine


(Except 2.2L Engine)
  1. Disconnect the negative battery cable.
  2. Remove the air inlet duct assembly, if necessary.
  3. Carefully relieve the serpentine drive belt tension, then remove the belt from the alternator pulley. Do not allow the tensioner to snap back into position once the belt is off the pulley.
  4. Remove the nut retaining the radiator hose brace to the back on the alternator.
  5. If equipped, unfasten the retainers, then remove the brace from the engine and/or the alternator.
  6. Disconnect the battery terminal boot wiring from the back of the alternator, then unplug the regulator wiring connector.
  7. Support the alternator and remove the mounting bolts (usually 2) from either side of the alternator, then remove the alternator from the vehicle.
To install:
  1. Position the alternator in the vehicle and loosely install using the mounting bolts.
  2. If equipped, loosely install the brace to the engine and/or alternator.
  3. Tighten the left or front alternator retaining bolts to 36 ft. lbs. (50 Nm), the right or rear alternator bolt to 18 ft. lbs. (25 Nm), the brace bolt to 18 ft. lbs. (25 Nm) and/or the brace nut to 22 ft. lbs. (30 Nm), as applicable.
  4. Connect and secure the alternator wiring.
  5. Carefully relieve the serpentine drive belt tension and position the belt over the alternator pulley, then slowly release the tensioner into position.
  6. If equipped, install the air inlet duct assembly.
  7. Connect the negative battery cable.

I hope helps with this. Good luck (remember rated this help).

Noisey drive belt, possibly alternator, belt

sounds like idler bearings but you have to release the tension to check,Also you can check the rest of the pulleys also at this time. I dont think you have to drop the engine.

Broken Belt under the 1998 Plymouth Breeze 2.4L DOHC 4 Cyl. engine.

Sounds like you have a broken belt that drives the alternator, water pump and maybe the power steering depending on engine type and size. Have the belt replaced before driving car as if you overheat the engine you could end up with major engine damage.The belt on the 2.4 litre engine is manually adjusted with a bolt on the alternator housing. To install this belt yourself maybe difficult if you do not know the routing of the belt around the number of pulleys involved. get help.

All belts came off , 1986 740 gle 4 cly. with air nedd to know diagram

On the 92, the belt closest to the engine goes around the power steering pump, water pump, and crankshaft pulley.

The second belt goes around the alternator and the crankshaft pulley.

The third belt goes around the a/c and crankshaft pulley.
