I hate to continue sounding like a newby but to Plymouth products I guess I am. Every time I try to do research to find a part things come up that have no relation to what I'm looking for. Trying to find a speedometer cable for a '74 RR produced things that might fit other models but not a '74 so I finally selected a generic one that I hope will fit. I purchased some reprints of the original shop manuals and electrical schematics but they cover several different '74 Chrysler products with no specific drawings of installations. At this rate I'll never get this car back on the road.

Now I would like to find the correct heater temperature control valve and how it's attached to the car. I have all kinds of offers from vacuum controlled to thermostatic controlled but the one that's on the heater hose in the car apparently uses a control cable and there are only two small holes in the fender that don't match any of the holes in the existing valve. If anyone has a picture or diagram of how it's attached and if it's correct for a '74 I would appreciate some help.
 
go to my mopar .com and see the pdf service manuals for free. you might want to join the ... for b-bodies only .com for more info you might need as a lot of cross-over on parts and info.
 
I bought both reprinted copies of the service (shop) manuals but they don't go into detail or have illustrations of the heater control valve. Since the service/shop manuals cover every body type developed by Chrysler in '74 the detailed drawings show locations of various parts but not how they're mounted or operated. The interior for the R-W body style is shown and how the operating cable is connected at the dash control but not the engine compartment valve.

I've been on every Chrysler body style forum I could find but apparently no one has ever addressed the subject before. I appreciate the referrals and advice and I'll continue looking maybe I'll find something. The last interior drawing is OK but my car has AC and except for the temperature control location and such the air vents don't apply.

I'm looking at my Plymouth Chrysler Plymouth Imperial service manual 1970 in the air conditioning section 24-37 at the top of the page on the right hand side you'll see that there's a water valve that's hooked to a control unit this one looks to be vacuum I believe yours is a manual inline this may turn off the water going into or restrict the water into the heater core better air conditioning as mentioned by the previous post so I don't know if you're using a Chilton's or a Mitchell's but they don't have the detail drawings on some of these but I've seen that in the manual I just have a 68 and a 70 and a 69 but I'll bet you if I went and look I could find that in a service manual by Chrysler Corporation
 
Thanks for the link but I have the valve, I just don't know how it's supposed to be attached to the car. I found some kind of adapter plate on the Classic industries site that is out of stock that might work but the thing should just bolt on some way without it. I've also tried to find a picture on some of the for sale sites of the engine bay that might give me a clue on the mounting but none close enough to help.
 
I just did a quick search and this looks just like your valve and it has the component for the manual lever cable to clip right on and hook to the lever and it just moves one way is hot all the time the other way restricts it so that the air conditioning will have colder air this isn't that difficult I don't know what you're missing here boss we're all trying to help you but I think you're making this more complicated than it is
 
The manuals I have were produced by Chrysler in '74 and reprinted by a company that supplies various body styles and brands but apparently they made a bunch of mods on the '74 that are different than previous years. The valve on the AC cars stops the flow to the heater coils and reroutes it back to the engine when the selector is placed to the cool position as near as I can tell.
 
Where is the one on your car attached to and does it have the same bracket as the one I sent you in the picture

I'm not trying to be difficult and the valves that are referenced are the ones like the one I have in the car. The problem is the existing holes on the fender well don't match the holes in the valve. As I said before there is an adaptor plate shown on Classic Industries but the valve should fit without it. The AC is factory stuff and not add on so the valve should be part of the original build. The attached picture was the best I could find, (not my car) of the valve and I can see the control cable attached to the valve but I can't see how the valve is attached to the fender well even if I enlarge it.

Right now it is or was hanging from what Ford calls an export brace by a tie wrap. This is the first Plymouth I've tried to restore and the nomenclature is different than Mustangs and I'm sure it's called something else. The bracket is the same as your picture but the holes in the fender well are closer together and don't match. I guess I could just drill new holes but it might cause problems later on.
 
Most people lose the bracket when they do some type of heater hose and or AC work there should be a bracket that you could make that would help support the low AC line the big one then this valve would attach to that so that it is supported also and helps hold up the heater hoses through the valve on 69 we had a bracket that went to the fender that the hoses set in not very good but it worked yours would be sturdier look at the bracket they have on classic look around through Steven's performance Tony's Parts these guys have cars and know the way the parts are supposed to go perfectly if you want the perfect restoration I would just have up a bracket myself and nothing bolted to the fender and be done with it
