Thanks Ronnie, good info.

While we are talking cooling, could somebody please tell me how the truck heater core would be connected? I assume one end of the hose should go to the passenger side pump where the shutoff valve is, but does that go to the top of the core or the bottom, or does it matter, and also assume the other hose goes to the rear port on the top of the head??

Cheers!
