What is This?

Post by GregL » Fri Sep 13, 2019 2:02 am

Hi Guys,
First pic is off the web. Second pic is of my engine (1957 312).
I just have a loose, temporary plug in my manifold in this spot. Is this a heater shut off switch of some type? I see it has a vacuum control.
I have two heater hose outlets on my water pump. Should the hose nipple marked #2 be removed and a plug installed there?
Appreciate any and all input.
Greg

Yes, hose nipple #2 should just be a plug. #1 and the vacuum valve are for the heater core loop.

Can anyone recommend a reasonable source for the heater valve?
It looks like they're pretty dear.

Check with any of the TBird parts houses. They are the same as the sedans so you should be able to get one from someone such as C & G parts

NOS periodically come up on ebay if you are concerned about authenticity.

I purchased a NOS one a couple of years ago after getting the seller to test it operated with vaccuum correctly. Just another option.

Authenticity is not an issue for me but thank you for the links.

Nice looking 312!

Although I don't have a care to look at handy I think No. 2 also serves as a connection point for the power steering pump bracket if the car is equipped.
