How do i change a water pump on a 2.2ltr engine

yes. the impellor on these engines have a tendency to come off the water pump.First you can see if the pump is working by removing a heater hose then have someone to start the engine. if the water sprays a good, solid stream out then the water pump is good. if the water just barely comes out or not at all then the pump is weak or "bad".

Removing and changing the water pump on a 2000 Grand Caravan should only be done if your van has a 3.3 liter or 3.8 liter V6 engine. On any other engine types, including four-cylinder engines, you must remove the timing belt from the engine to access the water pump, which is a dangerous task that can mess up the engine if attempted by an amateur.
The procedure is as follows:------------- The water pump is responsible for sending the engine coolant to the engine.First of all remove the serpentine belt then remove the plastic cove on the passenger side behind the wheel. You will have to remove the pulley. Once the pulley is removed unbolt the water pump and remove it. Clean the surfaces and install new pump. Draining the coolant and replacing it is advisable.Drain the engine coolant, twisting and removing the drain plug at the bottom of the radiator
-------------------Thats it.

3.0L DOHC Engine

1. Disconnect the negative battery cable. Drain the engine cooling system.
2. Remove the water pump drive belt.
3. Disconnect the radiator and heater hoses from the water pump.
4. If equipped, remove the A/C compressor-to-water pump brace.
5. Unfasten the four nuts securing the water pump to the engine and remove the water pump.

To install:



Fig. . 12: Water pump mounting-3.0L DOHC engine

1. Clean the water pump to engine gasket sealing surfaces.
2. Install the water pump using a new gasket and install the four retaining nuts. Tighten the retaining nuts to 15-22 ft. lbs. (20-30 Nm).
3. Connect the radiator and heater hoses to the water pump. Make sure the clamps are securely tightened.
4. If equipped, install the A/C compressor-to-water pump brace. Tighten the brace bolts to 15-22 ft. lbs. (20-30 Nm).
5. Remove the water pump drive belt.
6. Fill the engine cooling system, then connect the negative battery cable.
7. Start the engine and allow it to reach normal operating temperature, then check for coolant leaks and proper engine operation.

Hope this help; TY for using Fixya (remember comment and rated this).

change water pump

Changing a water pump is pretty basic. Since the coolant system is a closed system you only need to be concerned with that system. For instance you since you have to mess around with it anyway you might as well change the thermostat and flush the coolant system. Make sure your radiator hoses are in good shape and that's about it.
If you have basic mechanical skills and tools you will have no problem replacing a water pump.


As far as information with the actual replacement there are a number of experts here including myself that could explain how to do it.
However no matter how good our explanations are it just can't compare to a good repair manual.
A repair manual for your car at Auto Zone would likely cost between $12 and $15. It is a great investment if you are going to keep your car for any length of time. When you sell, it shows the buyer you took the time to maintain and repair it right.
I personally like Haynes Manuals.
I hope this helps.

I would follow the mechanics recommedations. I think he's taliking about the cam and crankshaft seals. Yes the water pump should be replaced as well. The pump that sprays windshield washer fluid onto the windshield is called the windshield washer pump. The water pump is on the engine and pumps water (coolant/antifreeze) through the engine to the radiator and heater core.

drain engine coolant.relieve belt tension .and remove the drive belt.remove upper fan shroud.remove fan or fan and clutch assembly.remove water pump pulley and coolant hoses from water pump.remove water pump bolts.then remove pump from engine.pay attention to bolts location because they are different lenghts.clean water pump gasket mounting surface dont scratch .or pump gasket wont seal and leak .apply sealant to water pump bolts.install water pump with new gasket.if gasket paper put a sealant on it.torque water pump bolts to 30 ft lbs.if you got a 2.2L engine torque water pump bolts to 18 ft lbs.install coolant hoses on pump .install water pump pulley.install fan and fan clutch assembly.install the drive belt .and the upper fan shroud.fill the radiator with coolant.then run engine to check for leaks.WARNING AS A SAFETY PRECAUTION REMOVE NEGATIVE BATTERY CABLE SO CAR WONT BE CRANK BY ACCIDENT. ALSOOOO DONT FORGET TO TURN OFF RADIO FIRST BEFORE DISCONNECTING BATTERY SO YOU WONT LOSE YOUR RADIO CODE.

the water pump on the 3.1 isnt to hard to change ...

1. Disconnect the negative battery cable.
2. Partially drain the cooling system into a suitable container.
3. Remove the drive belt guard.
4. Loosen the water pump pulley bolts before removing the drive belt. This should help keep the pulley from turning as the bolts are loosened.
5. Remove the drive belt. Remove the water pump pulley bolts and remove the pulley.
6. Remove the water pump bolts and separate the pump from the engine front cover.

if you see the water leaking form the front side of the engine usually from the water pump since the pump is not running you also wont get heat, bit when you pressurise the sys you are forcing the hot water into the core and you have heat, it is the water pump.

Hi Michael,

The motor shut off and the engine light came on, you won’t start right away and you wait a couple of days and start it again, sounds like your engine was over heated and because it is too hot and the engine frozen.

There are several kinds of engines, water cooling ,oil cooling and air cooling.

Over heated can cause many different problems for the cars, you should check step by step yourself.

Water cooling engine; if you know, you can help somebody.


1. Check the radiator see if you have enough coolant
2. Check the oil see if you have enough oil
3. check the water pump see if the water pump works fine
4. check the thermostat see it is function right.


Suppose your radiator has water or coolant, leave your radiator cap open, start your engine, let it is running 10 to 15 minutes and wait it is getting hot and see the water in your radiator, if the water moves, that means your cooling system works fine, otherwise either the thermostat frozen or the water pump was broken.

You mentioned when you re-start your car, sounds like a diesel engine, please check the where the noise from, if the noise from the water pump area, that means you need to change the water pump. When you change the water pump, change the thermostat at the same time, because when the engine over heated, the thermostat maybe damaged.

Oil cooling engine, check the oil pump. If the noise from the oil pump, you need change it.


Good luck,

Frank
