so i bought a 7 that was over heated and im swaping the engine out. I'm looking at the water pump housing it looks like it has copperish stuff ( yes technical term!! ) on the upper inside part that connects to the radiator . The bottom one is kinda stuck to the hose and i realy havent tryed to tak it off. how can i clean this or is thia one shoot and i should just get a new one. i have pics but dont know how to put them up. Any Ideas??????!!!

 

Might as well get a new one. It's only 60 bucks (up here in Canada, which means cheaper for you ), and that way you have a brand new pump without having to worry about a seal going out or anything.

 

Cool where can i get it cheap cause mazdatrix is WATER PUMP & HOUSING 86-88 N/T MANUAL 15-010C-8AF2 $320.59 !!!

 

Err excuse me. I meant water pump, not the water pump housing where it bolts to.

My mistake.

I have a water pump housing assembly though that I may be willing to part with. The copperish stuff you are referring to, do you mean the staining of the dried up coolant? The one I have has that too, although it's mostly white. The housing I have is in good shape..

 

While that isnt good, its fairly common, and as long as its not a built up sludge, its not bad. It wont really affect anything if its just a discoloration/staining. If youre really that worried about it, you can bead blast the housing. But I am very sure that did NOT cause teh overheating.

 

How do the inside surfaces of the pump housing look. That leak seal seal stuff is normally harmless to the pump area, but it could be hiding a small leak elsewhere, like in the radiator. I'd just be on the lookout for a radiator or heater core leak when you get the rebuild running.

 

I had a pump housing leak on an 87 about 4 years ago. It showed a coolant stain on the outside of the back of the casting. Bondo marine epoxy putty stick fixed it.

 

thanx for the info imma try to clean it off and use it on the new engine.
