on the heater system, which side is the send and which side is the return? What I mean is which side is the engine pumping into the heater core and which side is the return back into the engine? All hoses are disconnected and I have a different engine in the car now so I can't look at where the hose is going. I would guess that the heater control valve would shut off the water pumping in from the engine and the return would be on the other side. Neither the Chiltons nor the Haynes manuals have a cooling flow diagram. Thanks!

It does matter, system is designed to push the coolant in a certain direction and pull it back the other way. Reversing that flow can make it that much harder to get air out, cause poor heater performance due to low flow, or even (if one side has a restriction) erode the heater core and cause a leak.

We're not talking about spinning the water pump backwards... The only difference is the core in/out. AND if you do have a restriction, that should be addressed. Anyway, the answer was given. Good luck getting the car back together. -------------------- QUOTE (Araykhel @ Oct 10, 2011 - 6:32 PM) Today I learned that I need a turbo to complete me. |
