Does anyone know where I an find a heater control valve that will fit out 1966 Dynamic with air? I have searched Fusick, USA parts, Rock Auto, O'reillys, Autozone and all over the internet, any ideas where else to look?

 

I assume you are looking for the water control valve! What type of A/C?? Manual or Comfortron - they use different valves. I have a good one for the Comfortron system. part# 390380 The manual A/C uses part#389096 Both in Grp 8.848 Used manual valves should be much easier to find but I don't know how they held up. All models including Toro except 442 used the same part.

 

Do you need one for restoration purposes (correct part #) or just one that will function correctly?
I have a later one that looks a bit different, but works the same. I'd have to check to be sure it has the same pipe thread size, but if not, a regular pipe reducer bushing from a hardware store will work as an adapter. I've done that before since some Olds V8 intake manifolds have different size holes for the heater valve outlet.

Edit: I found an aftermarket replacement for you. Four Seasons #74606, available at Rock Auto for $40.79

 

Good morning! We just want it to function correctly and we do have a Comfortron AC. I have added a photo. I did not find one that looked like ours. We have it blocked off right now.

 

Ahhh... Comfortron is a different situation - takes a unique valve. But, there are several on eBay right now and bigoldscruiser above has a good used one. So you're in luck!

 

Just want to add that the 67-up valve screws into the intake manifold rather than your 66-back valve which fits inline in the hose. You can convert to the later one by removing the hose nipple from the right rear of your intake manifold and installing the new valve in it's place. The two valves function exactly the same way.

 

If still interested in the one I have, send me a PM and we can discuss it. Bruce

 

PM sent, Thanks for the help.

 

I lucked out and found mine on Ebay, yet to put it in and learn if it works.
