Isn't your Jeep a V8 . Mine is a 6 cyl an I believe I have a W/P leaking also. I was going to say give me some instructions . But I sure your a v8 man. Thanks
A water pump replacement is a water pump replacement, and the weep hole in the housing snout is standard (I've seen it for at least the last 30 years, myself.)
- Replace any screws you remove from the water pump. They're exposed to coolant, and will start rusting. Replacing them is cheap insurance. I prefer to use a copper alloy whenever possible (brass or bronze,) CRES (Corrosion RESistant alloy steel - "Stainless") is also acceptable. If you must use carbon steel, I recomment SAE5 instead of SAE8 (a bit less sensitive to corrosion,) and coat the screw with RTV before installation (which also doubles as a mild threadlocker.)
- The little nipple that the heater hose attaches to will likely be corroded. Threading is typically 3/8" NPT - go to the hardware store, plumbing section, and get a short (4" or so) BRASS 3/8" pipe nipple. Cut the threads off of one end and debur the cut. Slip enough hose over it so that you can apply TWO band clamps, there should be a minimum of 1/4" between the clamps and 1/4" between the edge of the clamp band and the bitter end of the pipe nipple (inside) or hose (outside.) This is to make up for the lack of a "bead" on the pipe nipple. Brass will last MUCH longer!
- On the 6-242, there's a heater hose that is moulded to a right angle to get down to the water pump - by selecting a nipple long enough, a 90* elbow, and a short nipple with the threads cut off of one end, you can eliminate having to find this moulded hose. I don't recall the length, and I did it on RENIX anyhow, but the idea applies. Clamp as previous.
- The use of a NEW band clamp is always recommended. If you remove a band clamp, throw it in your "spares" box/road kit for "just in case," but cheap insurance is always good.
If you don't have a manual, GET ONE. An FSM (Factory Service Manual) is best - careful shopping & bidding can usually net you on on eBay for less than $20. If you're in a hurry, go down to the local and pick up a Chilton's - but don't bother with a Haynes. (If you get a Chilton's, your ultimate goal is still to find an FSM...)
