Aluminum Water Pump Housing

some have said the aftermarket (all) AL water pump housings have a restriction in one of the castings that can cause low volume and poor cooling.

I think I am starting to agree with you on this. I bought an aluminum housing and waterpump from 440 source, and my car has ran warmer ever since. This year I am trying a remanufactured cast iron pump with larger fins in the aluminum housing to see if its better. If not, I'm going back to the cast iron housing.

If you buy that housing, let us know how it worked.
