Wrong! Standard threads on the fan clutch.

Let's hope you didn't blow the head gasket, because that will blow a hole in your radiator.

Well I replaced the radiator and reconnected all the hoses. I filled it up with water to make sure there were no leaks and it started dripping out from where the lower hose connects to the engine. I checked the hose for leaks and it's clean, I replaced the hose clamps and it's still dripping. It seems like its dripping from the water pump but I can't pin point it. Does anybody have any ideas?

Pressurize the system. You should be able to get a strong.stream you can see.

Just for the heck of it check where the shaft goes through the water pump. There's a small weep hole in the water pump casting on many of the pumps i've seen over the years.

If the shaft bearings / seals were shot it stands to reason that water would come out there and then run down.

Pressurizing the system is a better way of checking but if you don't have the equipment on hand this would be one possible cause of a leak that's hard to find.

Afterthought: Once everything is all said & done and you've got the system tight again keep a close eye on it for a day or two. Air always seemed to get trapped in the block of the two 4.9's that i ran. It was hard to purge them out after they had been drained.

A day or so later the coolant level would either drop or overflow the reserve a bit as the air was working it's way out.

It sounds like the seal in the water didn't take the heat. It's not a very good idea to drive it around because if that seal is going bad and allowing water into the pump bearing and I have seen where the pressure has actually pushed the bearing/shaft/and fan out of the pump body, at the least the bearing is losing it's grease.

Had that happen to me, actually. Scared the **** out of me when it happened. I thought I hit a deer at first. lol I was cruising down the road at about 70, the water pump pulley came off and lodged itself into my crankshaft pulley. Had a hell of a time trying to find a new water pump pulley, but thats a different story!

Are you sure the lower hose isn't compromised? Save yourself some cash and go get a pressure tester to find out exactly where the fluid is coming out.

Just a note, AutoZone loans out that radiator test kit. It's the best way to find all you leaks. Once you got them the system should hold 14 psi solid. Then you know all leaks are fixed.
