Decided to take the '49 out yesterday for one last spin. I installed a regulator valve for the fresh air heater a while back and noticed yesterday that the heater never really blew out warm air. Just cool air no matter where I turned the knob on the valve. Did I do something wrong on the install? Hoping someone might have an idea. Thanks

Could it be air locked? somtimes there is some air in the heater and the coolent will not push it out because the air compesses and the coolent will not move , the best way to get the last of the air out is to loosen the return line the lower one coming from the heater a little and let the engine run the air pocket sould come right out and the hoses should start getting hot .

Thanks, Pete. I'm going to give that a try in a little bit.

I am thinking you do not have the heater hoses hooked up properly.
Here is the factory diagram that shows the correct routing of the hoses.

I tried Pete's idea. Between that and adding about a quart of anti-freeze I now have heat. Thanks for the help.
