1957 Thunderbird Heater Valve
I need a recommendation on the best place to buy a new heater valve. Previous one suffered an internal rupture. It doesn't look to be really old so I'm wondering if it is one of low quality. Thanks for any suggestions!

Re: 1957 Thunderbird Heater Valve
I suspect the new replacements are all made in the far-east somewhere.
My 2 cents worth... they cost too much for how long they don't last. I have brass or steel 90° elbows for my two project Birds. If you're using a 'large opening' aftermarket thermostat the bottom end of the heater valve elbow fitting may interfere with the thermostat. (3rd photo) More thermostat info at this link... https://www.classictbird.com/Thermos...uctinfo/8575C/ If you want a new oem style valve, I suggest calling Hill's, Casco, Prestige or Concours for T-Bird parts, speak directly with a 'tech help' or 'parts' person and ask for their recommendation. https://hillsresto.com/thunderbird-center/ https://www.classictbird.com/ http://prestigethunderbird.com/ https://concoursparts.com/ .

Re: 1957 Thunderbird Heater Valve
You can eliminate the vacuum-controlled heater valve and replace it with a mechanical valve. The conversion kit costs less than $100 and is offered by most T-bird parts vendors. I've seen both plastic and metal mechanical control valves, but can't say which is better. You can probably find something similar at your local auto parts store, and it will be cheaper. Unless I'm missing something, dmsfrr's 90-degree elbows will eliminate your heater and defroster, unless he, too, converted to the mechanical valve, which would be located closer to the firewall, not on the engine.

The heater box in my running car has the heated-air vents closed, but I'm not sure how much heat it's actually keeping out of the car during the summer. I did buy one of the heater valve conversion kits for the disassembled car, hoping it will be a convenient solution. https://www.classictbird.com/Manual-...tinfo/18495MK/ .

The "spider valve" is on the side of the heater box above the passenger side floor. A heater control cable from the dashboard opens & closes the vacuum line that activates the coolant control valve on the front of the intake manifold. Last edited by dmsfrr; 04-20-2021 at 11:26 AM. |

I thought maybe a SPIDER VALVE had something to do with a spider's heart surgical procedure. Where do some of these names come from?

Re: 1957 Thunderbird Heater Valve
Well, No.1 the correct word/spelling is m-i-d-s-t snow flake.
And 'our' is referring to what group of people here? Your first post here was a bitching session as opposed to an introduction (THANK YOU FOR NOT) and at y-blocksforum you attempted to act as a FORUM MODULATOR. Are you for real or just another gas bubble in my butt? ... Watch For Return of Irritating Sex Jokes ...

Re: 1957 Thunderbird Heater Valve
Does C&G Ford parts still rebuild them on your core? Or was it just earlier built in models?

Re: 1957 Thunderbird Heater Valve
Yes, they advertise rebuilding either - https://cgfordparts.com/wwwsectionfi...rol_valve.html

Re: 1957 Thunderbird Heater Valve
I've gone thru 3 of these #@&% things!
The first was original, the second was a NOS which, as already mentioned, had 50 year old rubber seals in it and leaked within a couple years. So I got one from a Tbird supplier and it's worked for a few years so far ...... Mine leaked coolant, but the vacuum diaphragms worked fine, so I can't see the sense in changing to a mechanical valve since the seals are probably the same. |

I originally chose to go with a plain metal elbow at the front of the intake to avoid the cost and aggravation of picking between two choices of semi-expensive off-shore parts that fail too quickly. Yes the coolant circulates thru the heater core all the time but the ductwork between the fan and heater core is easy to block off (if needed) with a piece of cardboard or even a clean shop rag. An added benefit could be less corrosion buildup in the heater core??? I considered an elbow with a built-in hand operated valve (didn't like the look) or even removing all the heater hardware but wanted to retain a decent resemblance to how the car was originally built.

Re: 1957 Thunderbird Heater Valve
I recently bought a new heater valve from CASCO to replace one that was about 12 years old. Car sat a lot, so can't say for sure it was the valve's fault. No issues yet with the new one... **knock on wood**
CASCO Valve

Re: 1957 Thunderbird Heater Valve
My 57 Skyliner has never had a valve the whole time I have owned it. Of course, there is a door, and floor vets. 99% of the time the top is down anyways. I never much even gave it a thought until I read this thread. Interesting...

Re: 1957 Thunderbird Heater Valve
... hmmph ...
Just a thought, IMO of course. I never liked seeing the things on a FYB engine but I understand the need on a correct restoration. I like the idea of an elbow on the intake and an inline CONTROL VALVE in the inlet line to the heater core. These are available either vacuum or cable and can be sourced through MOTORCRAFT or DELCO.
