Water Pump Change

[RedPenguin]

So my water pump went out on me monday night. I was fortunate enough to have enough fluid in the block and radiator to get me to my destination and I don't have to worry about changing the pump till I get back from FL.

Two part question now. A)How hard is it to replace it?? I've changed my water pump on my jeeps before and it was as straight forward as it looked. I didn't need the manual to to do it.

B) Should I replace the timing chain along with the pump just like its recommended for my jeep when the water pump goes?

Well first theres no timming chain.
The job looks worse than it is. About 3 hours taking your time.
slip a rubber hose on the radiator drain valve so you can control the antifeeze otherwise it goes everywhere.
New stat at the same time.
If you do NEW water pump around 250, rebuilt around 125 but will need a core. No core with new one.
I suppose the hradest part is getting the fan off. Special tool needed or you can make your own.

Well if it looks harder than it really is, then I should be done in about an hour

I doubt you could get to the pump in an hour if it is a stock truck.

oh yes,

It will take more than 1 hour if you haven't done it before on the PSD.

Ther is about 12 Bolts or so on the Pump, Not to meation wrestling getting the Fan off of it!!!!

Took me 2 hours one time just for that!!!!!! I was on there GOOOOD!!!!!

I would say if I did it again 2-3 hours taking my time

Don't remember where I got these instructions but they worked for me:

1. Partially drain the engine cooling system.
2. Remove the upper radiator hose clamps and upper radiator hose.
3. Disconnect the radiator coolant recovery reservoir hose at radiator.
4. Remove the fan and clutch assembly using the Fan Clutch Nut Wrench and Fan Clutch Pulley Holder. Set the fan and clutch assembly in the fan shroud.
5. Remove the fan shroud screws. (2 ea.)
6. Remove the fan shroud, fan and clutch assembly. I lifted the shroud up some and pulled the fan and clutch assembly out first then removed the shroud.
7. Loosen the four water pump pulley bolts.
8. Remove the drive belt.
9. Remove the water pump pulley bolts and water pump pulley.
10. Disconnect the engine coolant temperature sensor.
11. Disconnect the heater hose and clamp from the water pump.
12. Remove the water pump inlet bolts and water pump inlet.
13. Remove the water pump bolts. These bolts are different lengths. There are nine bolts and three different lengths. Mark where they go.
14. Remove water pump and water pump housing gasket.
15. Clean gasket surfaces.

Installation
1. Install the water pump and water pump-housing gasket. I put a little grease on the gasket to help hold it in place.
2. Install the water pump bolts, torque to 15 ft/lbs.
3. Install the water pump inlet and bolts, tighten bolts to 15 ft/lbs.
4. Install the heater hose and clamp to the water pump.
5. Connect the engine coolant temperature sensor.
6. Install the water pump pulley and start the water pump pulley bolts.
7. Install the drive belt.
8. Tighten the water pump pulley bolts to 12-18 ft/lbs.
9. Install the fan shroud, and fan and clutch assembly. Nice to have an extra set of hands, but I managed it by myself.
10. Install the fan shroud screws
11. Install the fan and clutch assembly using the rental tools.
12.Install the radiator coolant recovery reservoir hose to the radiator.
13. Install the upper radiator hose and clamps.
14. Refill and bleed the engine cooling system.
