No flow from engine to heater

[Jim Haar]

I have ViNTAGE Air installed and have no flow of coolant from the engine to the heater.
Any thoughts will be appreciated, bad water pump,etc............

Primary question, how do you have it plumbed in?

[Jim Haar]

From upper outlet (pressure) to the heater s/o valve to heater inlet
and return to the lower pipe on the engine.

You might want to prime the heater core with coolant before finish connecting. There's likely air trapped in it and it's a pain to burp it.

[Jim Haar]

Heater core and hoses have been primed.

UPDATE;
I raised the front of the car and the radiator as high as I could per Waynes method and
filled the radiator until fluid came out of the reservoir tank. Now have flow to the heater and
pressure and return lines are both hot.
The top radiator line is hot and bottom line is cooler, fans come on and temp stays
at mid-range after 30 minutes idle. Seems all air is out of the system.

Congrats on clearing one more hurdle, Jim. I also learned from your experience. Do you have a bleeder port in your heater lines?

[Jim Haar]

No, I don't, I disconnected the lines at the engine and raised them and then filled
them so I know I don't have air in the system.
