Heater Core Supply?

It is the hose coming from the water pump that supplies the heater core with hot water right? I am putting a shut off valve in and don't want it to be on the wrong line allowing hot water into the core when I am using my a/c. Thanks

Re: Heater Core Supply?

I just looked at the Vintage air online diagrams and it says to put the valve on the intake manifold side hose and not the water pump side. I am glad I looked at the diagram first, I thought it would be the water pump side for sure.

Re: Heater Core Supply?

I'll just verify for you, the water comes out of the intake, the same passage that goes to the thermostat and OUT to the radiator, the intake side uses the small 5/8 line and the 3/4 return goes to the pump.
