Customer Question

I believe I have a failed Evans Tempcon heater control valve.
JA: Have you checked the coolant level? Has there been any leaking from the hoses?
Customer: I have it currently in a Ford shop, but the last time I had it out, the heater hose was hot and I bypassed it in order to vent cold air trough the vents.
JA: What is the model/year of your RV?
Customer: 2011 Forest River Georgetown Class A.
JA: Are you fixing your RV yourself? What have you tried so far?
Customer: The RV is currently at a Ford dealership with a list of issues being fixed. They have stated that the AC compressor is not picking up and are replacing it. They also will replumb the heater hoses and put a manual (open the hood) block valve in the heater line.
JA: Anything else you want the mechanic to know before I connect you?
Customer: The heater control valve appears to be no longer manufactured..

what information you looking for ??

Customer: replied 2 months ago.
Is this likely the valve and is their a replacement manufactured for it?
Expert:  Wayne replied 2 months ago.


Sorry for the delay

yes there is a valve to replace it

but my suggestion is install a ball valve in

the hose to shut off the coolant , works the best

it goes into the inlet line of heater core

I hope this helps you
