I'm even happier I bought a new water pump AND housing...

 

You really shouldn't use your stovetop for a workbench.

 

Hey, I had it in a box I brought back inside, and I just had the itch to take it apart and see the damage done over time. It just so happens that the only clear spot around me was in the next room, the kitchen, on the stove.

 

haha. yea thats def. rusted. distilled water FTW

 

it will rust if it sits a long time with any kind of water in it. Tap water causes mineral deposits to form.... which is a white crusty like substance.

 

it's just kinda funny to look back at when i talked to the former owner and he was like "it's fine and it only overheats when it gets above 85 outside" then it overheats in the middle of winter on the drive home :P well maybe THIS is your problem!

 

that is lookin nasty good thing you replaced it

 

Antifreeze is the corrosion inhibitor. Yet water cools better than antifreeze. Its a catch twenety two.

 

Your water pump was cavitating, look at the erosion on the pump housing, I think you have a blockage in the cooling system some where. That could just be from the rust deposits creating high pressure areas.

 

I don't think there's a blockage, because I was able to flush the system with a hose and DIY kit by Prestone. The original flush was horrible, tons of dirt coming out. No more overheating with the new pump and housing. Just need the friggin banjo bolt for the OMP that I tore off now.



But yea, I figure the parts that had rusted away kept any sort of pressure from being built up and so there was never a good flow of water moving, since it didn't *have* to move in that direction down the pipe.
