heater valve - Page 3

yeah, I saw that the drawing said "90 degree elbow" , "use pre-formed hose"
I'll have to get one or the other, which was it stock I wonder? preformed hoses I'd imagine.

I used the pre-formed hose, I believe it was off a Ford product. I took the old hose with me to match the Id of the hose, went to Advance Auto and got them to let me look through their assortment of hoses until I found the right one. I believe I trimed about an inch off each end and it's worked so far. Hth, Jarrell

Any more info? I don't have an old one to go by?....
Don't bother. I just did the same thing (looked through the rack at an Autozone) and picked one that looked like it should fit. If not, I'll go back and try another.

Even if it seems "okay", now would be the time to do it. It cost me less than $40.

I took it to a shop, he tested for leaks, said "it's a keeper", maybe not as good as a cleaning but at least I have some confidence I won't have to go back in there after a leak right away.

At least you know that much. A leak is much worse than no heat.

On my car, the hose coming out of the thermostat housing runs back along the head, around the carb, and back up to the heater control valve. I think this is how Opel used to run them. I found that making that 90 degree turn put a heater hose right under the fuel bowl or fuel line.

nearly done: everything in and working (except stereo....?? dead??)
dash, clock even works now -different thread, windshield back in, car run coolant capped off. Cool.
tonight; button up interior and well, drive it??
Wow, first real "work" on the GT, baptism by fire I hope.
Kinda surprised it works. I did rig the electric fuel pump to the rear defroster switch. Works fine. Fan motor, both speeds, no hideous noise. Both side vents fixed and re-ducted. Heater valve seems to be set up decently pics later. Thanks all. Not an easy intro to GT mechanics but so far I've not made anything worse, well beside the stereo is DOA where it worked before.

trying to replace the old one with a metal one and need to get the knobs off so i can slide the arms out of the old one. what deal with the devil do i have to agree to, to get these things off?

You are talking about the control plate and knobs I assume, these are easy, take a mini flat blade screwdriver and you will see underneath the knobs there are holes where set screws are in. Simply unscrew set screw a bit, and they slide right off
