I've got a 89 I6 and the other day it blew out its water pump. I replaced the pump and I found a leak, which I thought was the lower hose. I replaced that and I still have the leak The coolant is rolling down the lower hose and dripping at a pretty steady pace. I can't figure out where it could be leaking from. Any ideas?

 

maybe one of the tanks on either side of rad, leaking down onto the lower hose. I had a hole in one of the plastic tanks and just through a can of Bars leak in and its been couple months no leaks. *should replace rad but i cheaped out*

 

Went through the same thing on my 91 I6. Had the rolling leak on the bottom tube after replacing a water pump. On mine, the problem was that the hose clamp I was using kept backing out a notch (loosening) under pressure and would let coolant seep out from the top of the hose. It was annoying b/c the clamp was new. Once I put on a different new clamp, the problem went away.

 

Found the problem. I bought a remanufactured pump and the front bearing was leaking. Bought a new one and solved the problem. Anyone else have trouble with O'Reilly parts?

 

Glad you have her fixed, I prefer dealing with the dealership for obvious reasons. Believe parts are of better quality, and I like the good back room intel that is offered about our trucks. This versus, well you know.
