Control Valve after Service

[metstroke06]

Well after recent service at my local ford dealer, I looked at the heater valve on top of the heater hose that runs to the heater core, and there are no longer any vacuum line running to it. Is this strange? Isn't this valve suppose to close when you run max ac to turn off hot water to the heater core? It's very strange considering 3 weeks ago they replaced my "heater control valve" at the dealership. Is this normal?

Yep. Supposed to have a vacuum line running to it.

Thats what I thought. There is typically a grey vacuum hose running to the front nipple there. I can't find a line anywhere! I had the headgaskets done, and its like there isn't a vacuum hose anymore. All the other vacuum hoses have correct endings, including a grey line that runs into the ac unit, the other end of that grey line runs into the cab with a black vacuum line. I'll probably take it in tomorrow and be like hey, where's my vacuum line?

By the looks of your 1st and 2 nd pic, the gray line is right there. Plug it back in to see if you have any issues.

Naw, that grey line has an end...


It runs off into the cab with a black line, like it's suppose to..

You can turn on the key, and see if the pump runs. If it does and doesn't stop, there's a leak. Then just find it. If it stops, I would think it made full vacuum and got shut off.

If they have that gray line going to the HVAC box, pull it off there. It's just a stud to block up the hose if you don't have the inline valve.
