Under Hood Question
I Have A 2005 Ex With A 6.8 V10. While Looking Under The Hood I Noticed A Small Gray Tube Which Was Hanging Freely In The Engine Compartment Next To The Air Condition Compressor. I Followed The Tube Thru The Firewall And Into The Rear Of My Glove Box. It Appeared To Connect To The Rear Of The Air/heat Control Unit.
While Searching For The Proper Fitting, It Appears To Fit On A Servo/or Control Valve Which Is Fixed To A Heater Hose Which Runs From The Right Side Head And Into The Firewall. I Do Not Want To Connect The Tube To This In Case It Is Not The Proper Place.
Can Anyone Offer Any Assistance As Ford Would Probably Charge Me Just To Answer My Question!

i have a 2000 X with the 6.8L and i think i can help.
This is what I see under my hood...
To the right of the compressor, there is a little T-fitting of some type with 3 coolant (i guess) hoses, one of which attaches to a port on the intake manifold/engine/head. The other two go somewhere else (i think through the firewall). On top of this T is a 3-4" black diaghram looking thing with a little grey hose that attaches to it. If this is the grey hose you are talking about, it is very small, maybe a few mm in diameter. I didnt get a chance to trace it, but I only saw one.
Basically, if the little diaghram thing doesn't have a hose on it, and you have a hose that fits, I'd sayyou are probably ok to plug it in.
If I had to guess, I think that that is some type of vacuum hose that opens a valve in the hose T. I heard somewhere that the A/C is cooler if the engine doesn't pump hot coolant through the heater coil thing. So I think that when the heater is activated, it opens a valve in the T (via the little Grey hose) to either open or close the coolant path. But thats just a guess.
good luck and I hope that helps!

Thanks For The Help, Looks Like You Were Right. I Was Looking At Photos On Ebay Motors And Saw Several Photos Of The Engine Compartment In Which It Displayed The Gray Hose Connecting To The Valve On The Heater Hose. Merry Christmas!
