WATER PUMP PROBLEM

Water Pump
REMOVAL & INSTALLATION
CAUTION
Never open, service or drain the radiator or
cooling system when hot; serious burns can occur from the steam and hot coolant.
Also, when draining engine coolant, keep in mind that cats and dogs are
attracted to ethylene glycol antifreeze and could drink any that is left in an
uncovered container or in puddles on the ground. This will prove fatal in
sufficient quantities. Always drain coolant into a sealable container. Coolant
should be reused unless it is contaminated or is several years old.

2. Remove the timing belt as described in this section.

Very easy. You can do this. Just take off the serp belt by pulling down on the tensioner with a 15mm wrench. Then remove the three or four bolts for the water pump pulley. You will need to be under the vehicle for this. Then remove the five or six bolts for water pump. Pull the pump out and install new one in the reverse order. Just slip the belt off the water pump so you don't have to figure reroute the whole thing unless you are replacing it. Also clean the mating service for the pump before installing the new pump with the new gasket. Should take about an hour

Hope helps (remember comment and rated this).

1. (This is for a 2.2L engine) If equipped with an automatic transmission, remove the exhaust manifold.
2. Drain the cooling system.
3. Remove the thermostat housing to water pump feed pipe bolts.
4. Remove the thermostat housing to water pump feed pipe.
5. Remove the thermostat.

Need to know engine size but usually water pump is directly connected to the lower rad hose. Moe

3.0 Escapes DO NOT use a tensioner for the water pump belt. If you get a clear look at your water pump, you'll see the pump itself is bolted to a pump housing. The pump housing is bolt to the block using three bolts which differ from the actual water pump bolts. Remove the three bolts from the pump housing to relieve tension on the belt. The cooling system will remain sealed. Change the belt and reinstall the bolts. (The three bolts use washers)

this one of them 4x4 jeepy things , you have to remove the viscous fan to get at the bolts if memory serves me i think their is 5 or 6 bolts

You have to remove the engine mount next to it, then remove the 4 bolts in the pulley Make sure you support the engine with a floor jack, use the jack to raise the engine a few inches on the that end helps getting the pulley bolts out.

Unfortunately, u must remove the timing belt. This is why it is recommended to change the water pump when the timing belt is changed.
Here's the procedure : Disconnect neg. battery cable, remove splash shield at wheel well, (after removing wheel to help gain access, turn the engine to align timing marks and set #1 cylinder at top dead center on the COMPRESSION stroke. Once this is done, u can NOT disturb engine or u will have a fun time trying to figure out how the heck to set the timing. Drain anitfreeze, remove timing belt, remove water pump bolts (be aware that bolts may be different lengths, don't mix them up, remove water pump and O ring.
Put it back together: install new O ring and water pump, be careful Oring doesn't slip or move out of position, tighten to 9 ft lbs, install timing belt, refill antifreeze, reconnect battery cable, start car, check for leaks, bleed cooling system, replace splash shield.
