Water pump The water pump has been leaking. How do I take it out? So far I have removed the alternator and I am trying to remove the airconditioning unit. I have no manual.

The water leak will require hands on checking. As far as the stalling when the jumper is removed that is easy, you engine Alternator is defecive.

Remove the belt (remembering how it goes back on, drawing the belt routing usually works) I find it best to remove the two top shroud nuts 13mm. Also removing the air box will allow for access under the alternator. Two 10mm bolts hold in the water pump. Clean the sealing surface.. install new water pump and gasket. Re-install components. Top up lost coolant making sure air is blead out, otherwise you will run into overheating issues.. Good luck

1. Disconnect the negative battery cable.
   
2. Drain the cooling system.
   
   CAUTION When draining the coolant, keep in mind that cats and dogs are attracted by the 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.

Sure hope this helped you and good luck with the repair.

Remove the radiator upper hose. Remove the emmision control canister. Loosen the alternator belt. Remove the fan blades and the alternator pulley. Now the pump is all exposed for removal and replacement. Just do the reverse when putting all things back.

Water Pump! Why In the world Did you get one of those?? 4 real.. f youve ever been to Korea ( I have for 6 years) Ud know better.. Im sorry.. Its the water pump.. Its the head gasket.. Its everything you can imagine.. Get rid of it.. Ive answered so many ******* stupid questions on here and only MAde 6 bucks.. Im sick of it.. so take this free advice.. Thanks

1. Remove coolant
2. loosen off alternator belt tension
3. loosen off power steering pump tension if applicable
4. Same with AC if needed
   
5. remove fan hub bolts
6. remove belts shared by water pump pulley
   
7. remove hoses from water pump
8. remove heater core hose from water pump
9. remove alternator support bracket bolt thru water pump housing
10. remove power steering bracket support bolt if applicable
11. remove AC bracket support bolts if applicable.
12. Now remove water pump housing to block bolts(remember sequence)
13. using a pry bar or large screw driver, gently pry the water pump until it releases from the block
14. clean all old gasket material from connecting surfaces
15. Place new gasket in place with a little bit of spray tack
16. then re-install water pump and install bolts as they came out(some are longer than others)
17. Re-assemble all parts in reverse order of removal
18. fill system with new coolant
19. start vehicle and test for leaks before driving anywhere(make sure you have a drop pan under the vehicle
20. Let the vehicle come up to operating temperature,,do final check for leaks with Radiator cap on
    
21. If you have access to a cooling system pressure pump and tester, it would be easier to use this tool to test system.
22. Road test vehicle, add fluid if necessary, enjoy driving.!!
    

When it does not pump the water at all the engine brakes after few miles.

Check if there is any leak in the water lines, or in the radiator.

If there is no leak, that means that the water is being vapourized inside the engine because of a defective head gasket.
When this happens you often can also get white smoke coming back from the exhaust.

You probably need to replace the head gasket.

I've found the Haynes Repair Manual that you can get at Auto Zone to be the best one there is. They have step by step instructions with pictures on repairing or replacing just about anything on your auto. You can get them for around $20 - 25. Is yours a 3 or 4 cylinder?

1. Disconnect the negative battery cable.
2. Drain the cooling system.

CAUTIONWhen draining the coolant, keep in mind that cats and dogs are attracted by the ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground.
