Cold Blue Posted October 27, 2018 Report Share Posted October 27, 2018 My 48 Plymouth Special Deluxe's cable controlled heater valve is missing; has been since I got the car. Looked on-line till I am blue in the face, but cannot find one. Did find an NOS one that had been sold - $525.00!!! was the price....Ya'll got any leads as to where I could find one? I know that I can install a manual shut-off valve for summer time use. Maybe that's the best option? Thanks! Quote Link to comment Share on other sites More sharing options...
captden29 Posted October 27, 2018 Report Share Posted October 27, 2018 i cannot help you locate one, but i do know there are companies like texas air that rebuild them. maybe they can help. i took mine off and had the heater core fixed about 2 years ago and now i forget where the heater valve even goes back. it is a 54 Windsor and i guess somewhere there is a diagram for this. good luck finding one. i do not think i have an extra, but i will look. dennis Quote Link to comment Share on other sites More sharing options...
Worden18 Posted October 27, 2018 Report Share Posted October 27, 2018 Unless you're dead set on having an original, just get an after-market one. the one on my 51 Dodge is for a late model Toyota pickup. Works just fine. Do a search, I know there's information on this forum about those. Quote Link to comment Share on other sites More sharing options...
Cold Blue Posted October 27, 2018 Author Report Share Posted October 27, 2018 Thanks guys! Capden29 - I wish I had the original - I would get it rebuilt in a heartbeat; unfortunately I do not. Worden18 - Thanks so much - I will look into putting a later model valve on my 48! Quote Link to comment Share on other sites More sharing options...
Andydodge Posted October 28, 2018 Report Share Posted October 28, 2018 I dunno if this helps, whilst this heater valve is on the 318 Poly in my 1940 Dodge the actual valve is one that I found when I installed the heater and is or was at least a very common aftermarket style on/off valve.........it just screws into the water crossover port on the intake and uses a cable which I disconnected yrs ago as I wasn't using the heater anyway........you can see the bracket that points toward the radiator, this bracket holds the clamp that held the cable.....I have seen these type of heater switch used on all sorts of cars here in Oz and would think they maybe or should be a similar thing available in the US............I know this valve still works, at least it opens and closes as I had to remove the intake manifold recently for some welding repairs and whilst it was off the car I checked the valve and apart from some very slight corrosion which I cleaned out the valve was fine.....its been on the car for at least 30yrs, I only ever used the heater about 3 or 4 times so about 10 yrs ago disconnected & removed the cable, the switch is left in the "off" position............check a local radiator repair shop as they tend to have this type of switch as a replacement for OEM ones...............andyd Quote Link to comment Share on other sites More sharing options...
plymouthcranbrook Posted October 28, 2018 Report Share Posted October 28, 2018 I bought one from Danchuk for a 57 Chevy that was brand new for $80.00 or so and it only needed a little engineering to work well Quote Link to comment Share on other sites More sharing options...

Cold Blue Posted October 28, 2018 Author Report Share Posted October 28, 2018 Hey DonaldSmith - Yep, I can see how it works but I am puzzled as to where the red "reinforced heater hose" going to the left in the picture goes??? Quote Link to comment Share on other sites More sharing options...

DonaldSmith Posted October 28, 2018 Report Share Posted October 28, 2018 Answer to Cold Bliue: The top red hoses are for the dual heaters (Top-of-the-line DeSoto). The lower red hose is the drain hose for the air distribution box, or whatever they called it. In theory, any water that gets in the cowl vent, drains out. Right.

Cold Blue Posted October 29, 2018 Author Report Share Posted October 29, 2018 Thanks DonaldSmith for the explanation. I wish I had just a fraction of the knowledge ya'll have about these vintage cars. Plymouthy apparently knows about every nook and cranny! I am in awe...

Plymouthy Adams Posted October 29, 2018 Report Share Posted October 29, 2018 bit pricey, I think the same, go to the big box store...ask for the 4 Seasons Catalog.....purchase by need, not application.... Quote Link to comment Share on other sites More sharing options...
mmcdowel Posted October 29, 2018 Report Share Posted October 29, 2018 I had a guy in California rebuild mine....I'll find the link....perhaps you can contact him and he has rebuilt extras. Excellent work. Stay tuned. Quote Link to comment Share on other sites More sharing options...
mmcdowel Posted October 29, 2018 Report Share Posted October 29, 2018 Easy enough...."heatercontrolvalve.com". He says best to call 760-749-3488. My old one came back looking like brand new...about a 2 week turnaround. 2 years ago...so far so good.. Quote Link to comment Share on other sites More sharing options...
Young Ed Posted October 30, 2018 Report Share Posted October 30, 2018 I believe this is the one you seek for dual heaters Quote Link to comment Share on other sites More sharing options...

I had the same package but mine had the $$$ aluminum "Y" valve in it.....as used with the dual heaters in the 1941-48 Mopar cars.. see Ed's post above. These valves are very difficult to find in good working condition or even harder new. Quote Link to comment Share on other sites More sharing options...

9 foot box Posted October 30, 2018 Report Share Posted October 30, 2018 Four Seasons has an online catalog. I think 74827 has a flat lever, 74828 a round one. A 74682 is nice but it won't clear the firewall to install. You can use RockAuto part no. search, for more info. Quote Link to comment Share on other sites More sharing options...
HotRodTractor Posted October 30, 2018 Report Share Posted October 30, 2018 I think this one looks promising: http://ecatalog.smpcorp.com/fs/#/vehicles/parts/num/74765?type=s Quote Link to comment Share on other sites More sharing options...
