So I have been wondering about this part that has been laying down on the backside of the engine and to my understanding it is a heater control valve laying back there with a small vaccum line attached to it..... and I want to hook it back up the right way since this is a restoration I am doing..... I want the heater to work right, I have all the top end parts off my engine and I want to get this back where it is supposed to go..... anybody have any ideas and or pictures of where this is need to be hooked back up right.... To my understanding it connects to some hoses that go into the fire wall is that right????? bought this truck 6 months ago so I am new to this any help will be greatly appreciated.... Is this better explanation

 

Look for a spot in the firewall with periods and tips on punctuation. That way all your thoughts don't run together and someone can understand your problem...

...sorry, feeling a little ornery today...

 

Thought you might be smart enough to put it together did not realise we were being graded here!!!!!

Going on the assumption you have either factory A/C or a deluxe Hi-lo heater (standard heater didn't have vacuum lines) here's where the vacuum operated hot water shut off is located.

 

D4AZ-18495-A (replaced D1AZ-18495-A) .. Vacuum Controlled Heater Water Valve (Motorcraft YG-136) / Available from Ford

MSRP: $34.46 // FTE Ford Dealer Parts Dept sponsor tousleyfordparts.com online price: $18.95 / Tousley Ford ~ White Bear Lake MN

This valve is a notorious POS! Gets stuck open/closed/partially open.

Applications: 1973/79 F100/350 & 1978/79 Bronco ~ Use with factory installed integral A/C or Hi-Lo Comfort Vent System only // Misc. 1971/78 FoMoCo Passenger Cars.

No heater water valve on F100/350/Bronco if standard/high output heater or dealer installed A/C.

 

Matt,

Using proper sentence structure, grammar, spelling and punctuation is simply common courtesy on an Internet forum. If you're too lazy to compose your thoughts and communicate them in an intelligible manner...well that doesn't speak very highly of you.

When I see a post requesting information from someone who doesn't take the time to write a post that reasonably conforms to the conventions of the English language. I typically think "If they're not willing to put some effort into their post, I'm not going to waste my time replying to someone so thoughtless".

I strongly suspect there are a lot of forum members who think as I do.

[BTW, my late father taught high school English well before the day of the computer with spell check. His rule was if a student turned in a paper with more than three mistakes on a page the student had to recopy that page. I met many of his students in later life and they all told me they thought he was a "tough, but fair" teacher.]

Happy New Year!
