In case the DT thread ever disappears:
Well, long story short:
I took my truck into a decent mud hole to try out my snorkel. I had muddy water pouring out from between the hood and top of fenders. The snorkel more than did it's job, as everything was kept dry in the air box. I didn't think it was that bad so I didn't take any pics of the mud hole.
The next day, my truck was squealing from the front. My initial thought was my idler pulleys, like it was last time I got back from Rausch Creek. I replaced both and still had the squeal. I then replaced the idler tensioner assembly which came with a new pulley on it as well. Still squealing.
I took it to a buddy's house and he narrowed it down to the water pump.
I purchased a new water pump from Auto Zone. I was having second thoughts about doing it myself, so I called the Dodge dealership to see what thier cost would be. $560 and some change. Needless to say, I did it myself.
I bought a jug of antifreeze, new fan clutch ($52 NAPA Part #271621 Heavy Duty, Reverse Rotation,W/O Snow Plow
Auto Tranny) from Napa, hose clamp, and thermostat.
1. Take antifreeze overflow jug off. (two bolts) Drain all anti freeze and disconnect hose clamps.
2. Take fan shroud off. (two bolts and then lift up on it.)
3. Take off three nuts and a bolt out of the bracket that hook alt, air cond compressor together on the top middle of engine.
4. Remove serpintine belt.
5. Remove two idler pulleys, and idler tensioner.
6. Disconnect two hoses on the bottom left( as you are looking at the truck from the front) of the water pump, and also the radiator hose on the bottom left.
7. Remove 10 bolts that hold the water pump on. They were very easy to take out, meaning they weren't siezed up at all. Water pump came off super easy.
8. Pull water pump out. I still had the fan conected because I was unable to remove it while on the truck. I didn't have the tool to hold it in place so once I had it off, I heated the nut with a little propane torch and it came off easily after I heated it up enough. There are multiple fans and fan clutches for the dodges. We have the severe duty, counter clockwise fan rotation on our trucks.
10. Clean the water pump mounting surface on the engine and flush out the radiator and motor.
11. I added a couple drops of 3 in 1 oil to the inside of the water pump near the bearings for initial start up lubrication.
12. Insert new rubber gasket into new water pump with a SMALL amount of gasket sealer and re-install in reverse order.
13. Install new Fan Clutch and tighten.
14. Fill Radiator and add 1/4 bottle of 3 in 1 oil into radiator, it helps with lubrication of water pump for remainder of life.
15. Check all hose connections and start up. Let it warm up to full operating temp.
16. Let it cool down and check Radiator fluid level and top off if necessary.
17. TAKE HER FOR A SPIN!
