What water pump did you bolt on?
hesco's $150 water pump fits a CNC machined aluminum impeller to an OEM housing. Aluminum is the second worst impeller material, next to plastic. This is a race part.
Explain to me why aluminum is bad? How much of a new cars engine is aluminum? Usually just about every part that comes in contact with coolant: heads, block, radiator, intake, etc. I run a Hesco pump because I believe it is the best design out there. Now I might be proven wrong in a couple of years, but for now I can wheel out here in 110 degree heat with my AC on and keep my coolant temp 200 degrees all day long.
Same here, no problems with hesco. Not sure how having aluminum impeller is any different than any other aluminum that contacts coolant.
Hallo Jeepers. About Waterpumps, what are the most common failures then ?
The impeller degrades from "cavitation erosion", not so much from galvanic corrosion. tiny bubbles...

I would agree with this also, but part of Hesco's water pump design is anti-cavitation. If you look at their impeller it is shaped way different than a stock impeller that acts like a paddle instead of a pump. I have witnessed aluminum props on boats errode from cavitaion, but in this application I think the impeller will outlast the bearing.

Man there are some aluminum haters here... I guess I won't say anything about how I can't wait to build a stroker with an aluminum head.
