Need Help: Water Pump Removed - Heating Issue?

[GregWeld]

And -- as long as I'm writing a book on cooling...


Is your bottom (suction side) hose reinforced?? It should have a spring inside of it to keep the hose open... they can be sucked almost closed at cruising speeds if they're not internally supported. Lots of guys just chuck the spring --- dumb move guys! These pumps move a LOT of water volume... you'd be shocked how much suction they can create.

All the fans in the world won't help you if the hose is collapsing....

You should be able to reach down and squeeze the hose to check for the spring.

You can also visually inspect the hose with the car running and have somebody rev the car up and watch to see if the hose is trying to suck in on itself.

I dont believe there is a spring. I havent squeeze it while running. It is shaped perfectly to connect my rad to the water pump. I can try to see if there is a spring today.

I have not seen it collapse on itself
