Heater Control Valve
 

So I was reading other posts about heater control valves for the inlet side of the heater core. I remembered I had one and a cable, so without destruction of the vehicle, I added one! Lets see how it helps on the drive home today.

What's the deal with that? I bypassed my control valve over the summer because it was letting in heat. It helped. My son is going to be in OC this weekend and his is going to stop at the truck and car shop and pick up an original vacuum controlled valve. I expect it to work fine. So, why do you need a cable operated valve?

Just curious! :chevy:

why is your vacuum advance on your distributor disconnected?

I have both in my 71 C-10 and the 56 Bel Air. I shut the manual one off during the summer to help on the AC temperature inside the cab. If the heater is letting hot water pass it makes the ac temp go up. Mine was good for almost 6-10 degree's inside the cab.:chevy:

Non-AC truck, no valve originally.

I re-curved the distributor and set it to total advance of 38 degrees, then adjust back for pinging from there. Runs like a champ..

Can you tell me about your fire extinguisher ?

Re: Heater Control Valve
 

Really?

That fire handle is kind of a cool pun. If heat is coming through the vents in the summer... you'll feel like your putting a fire out! :lol:

It looks cool but (and maybe I'm just old and grumpy this morning) I'd be hesitant to label ANYTHING as fire suppression that wasn't actually. Otherwise I think it's awesome.

Agree, but it is what i had in the garage.

I have a complete AC system for it that I will install when i want to disassemble the truck.

Very nice, you can open it on those cool fall evenings.
