What is it?

[Kids_Ride]

The wife had the X towed home today. Looked like a blown upper radiator hose. Since it was giving me some leakage a month ago, I went and replaced it. (it was a GATES and only 2.5 yrs old..) Not much fluid was gone, so I capped and started it up again. Seemed ok, then I came out later and coolant was flowing out from the bottom, like behind the steel wheel on the crane shaft... (if my terms are correct) Can't really see the leak, but I think the only thing back there is the water pump. I did put this Airtex AW4114 on, in Aug 2006.. got about 100k out of it.

What do you think;
- It's the pump or
- It's something else

I do have the Rotella Red 300k coolant in, did that about 185k?

If you crawl under and look up at the waterpump, you will see a hole just rearward of the pulley. That is the venthole for the waterpump shaft seal, and also where coolant should NOT be dripping out of

You should be able to see the coolant coming out of the weep hole behind the water pump pulley. That will confirm that it's the pump. If the coolant was low enough that the pump went dry, that could possibly take out the seal. Crawl underneath with a strong light and look upward past the crankshaft pulley.
