Replacing Water Pump
#1
#7
Fan clutch nut? Take the fan and clutch off as one. 4 7/16" bolts which are fairly easy to remove. The fan is the easy part. The difficult part is the water pump bolts. If you have any issues with rust, you will want to soak them for a few days.
Here is how I did mine last week.
1. Drain coolant from radiator at the Percocet on passenger side tank.
2. Remove intake hoses(ease of access to pump)
3. Remove upper radiator hose.
4. Unbolt the 4 nuts on the fan that go into the water pump. I believe they are 7/16".
5. Unbolt the two 8mm nuts on the top of the fan shroud.
6. Remove the serpentine belt.
7. Remove fan and shroud together.
8. Remove the 3 14mm bolts from the power steering/ A/C bracket.
9. Remove 13?mm nut from said bracket.
10. Move entire assembly off to the side and bungee or tie it in place.
11. Detach lower rad hose from pump.
12. Detach the 2 small coolant lines from the top of the pump.
13. Unbolt the pump. 5/8 and 13mm are required I believe.
14. Clean threads if bolts.
15. Clean gasket surface.
16. Mount new pump and gasket.
17. HAND tighten the bolts.
18. Reattach and assemble everything in reverse.
19. Fill system with coolant.
20. Start trucks and allow it to run until the thermostat opens.
21. Once it is open, add coolant till filled and check for leaks.
22. Shut off the truck and relighted ALL of the water pump bolts. Be careful as everything will be hot.
23. Pat yourself on the back, enjoy a cold drink of choice and relax. Wasn't that bad was it?

You should be aware that the bolts holding the water pump on have a tendency to seize to the water pump housing. Very common. If you search this forum you will find several threads about it. If you can see white powder around the bolts it is the corrosion that causes the problem. I guess they can rust and break also, but I've never run into that personally. One way or the other, soaking them with penetrating fluid is a good idea.
If those bolts do break off it can become much more of a job, often requiring the timing cover to be pulled.

Got er done
Hey thanks for all the help fellas. I got everything done today. Didn't have too much of a problem. Couple of bolts were a little tight, but I managed to get them off ok and cleaned them up. Put anti seize on them when I reassembled everything. Did more damage to myself than to anything else. I've GOT to get me a pair of those mechanic gloves. I'm getting a little old now and my skin is getting thinner I guess. Every time I bump into something, I start bleeding. Thanks again for the help.
