Need to replace water pump, on a 95 Jeep Grand Cherokee, 4.0 6cyl! Is it simple enough for a novice? Getting estimates of approx. $250.00!!
Hello Sir,
Here's a step by step proceedure to remove and replace the water pump on your Cherokee.
Be advised,all 4.0L engines, some 2.8L engines and some 4.2L engines have areverse rotating water pump. You can ID these from the word REVERSE orREV imprinted or cast on the housing and/or fan. There will also be an'R' stamped into the impellor.
Make sure your replacement pump is the correct type, If not, expect some major turmoil.
The procedure:
1. Remove negative battery cable
2. Open radiator valve - drain cooling system
3. Remove cooling fan and shroud
4. Remove belts (see my tip on serpentine belts if needed)
5. Remove water pump pulley from hub
6. Remove hoses from water pump
7. Remove accessory brackets from the water pump.
When removing the P/S pump and/or AC compressor, leave the hoses attached and move them out of the way.
8. Remove the remaining bolts and detach the water pump from the engine.The bolts are three different lengths. Make note of where they camefrom.
9. Compare the new and old pumps. Make sure they match.
10. Scrape off the old gasket material.
11. Apply a thin continuous line of RTV High Temp sealant to the water pump side of the gasket.
12. Put a couple bolts through the pump to hold the gasket in place and mount the gasket.
13. Apply Another coat to the other side of the gasket.
14. Attach the pump to the engine. Screw the bolts in finger tight.
15. Attach the remaining bolts.
16. Tighten them up in 1/4 turn increments.
17. Re-attach all the stuff you removed
18. Refill the coolant, adjust belt tension.
19. Run the engine and check for leaks.
Hope this is very helpful

Look at it.. does it look like something you can do.. if it does take a crack at it they are really easy but some times you have to remove the fans and things like that.. if you look at it and your like "what the hell" have someone else do it.. if your into fixing yoru own stuff then give it a shot just take a bunch of pictures so you know how things go together especially with the brackets to the pullies and accesories.. also get the repair guide for your vehicle at autozone it's worth its weight in gold
