64Rivvy Posted January 5, 2020 Share Posted January 5, 2020 Does anyone have a pic of the factory correct mounting location for the heater control valve on a 64? I just fabricated a bracket to mount a new manual control valve to the oem bracket. However, I dont think where it was previously mounted was correct and I want to make sure to put it in the correct location. Thanks, Raul Link to comment Share on other sites More sharing options...

I know the 63 Riv water control was manual, but very hard to find and expensive when you did find one. I thought and I’m happy to be wrong the water control valve was vacuum controlled. I have a 63 and my mounting hardware and bracket were gone. Turbinator Link to comment Share on other sites More sharing options...

I am supposing I have it the correct position. I put the replacement water control valve in the same place the faulty manual control was mounted. No need to answer I can look in the SERVICE MANUAL!

64Rivvy Posted January 5, 2020 Author Share Posted January 5, 2020 Thanks guys. I have looked through the diagrams in the shop manual but have not seen any illustrations that show exactly where the valve is mounted on a 64 and I'm not finding any existing holes where I though it would go on the pass inner fenderwell. To my knowledge the 64 used a manual gate valve that is currently about impossible to find. There is one on ebay now for 250 and I'm not paying that . I am using a manual valve from a 70s bronco that works fine and I fabricated a bracket to mount it to the original oem bracket. Link to comment Share on other sites More sharing options...

DrownedRiv Posted January 5, 2020 Share Posted January 5, 2020 Went thru ny phone and found some old pics of under thr hood of my 64. Hope this helps. Link to comment Share on other sites More sharing options...
RivNut Posted January 5, 2020 Share Posted January 5, 2020 Don't try to use a 64 temp control valve on a 63 or vice versa. The levers work opposite of each other. Don't forget the wire that's connected to the lever on a 63, it controls an air door. Link to comment Share on other sites More sharing options...
64Rivvy Posted January 5, 2020 Author Share Posted January 5, 2020 (edited) Thanks guys. I printed out diagram 11-37. Between that and these pictures I am golden. Diagram 11-37 threw me off when I saw it in the manual bc it says it's for then4700 series which is a wildcat and riviera is supposed to be 4800 but that def looks the closest to my ac system setup. Thank you all for the help. Will post some pics when I get it mounted. Raul Edited January 5, 2020 by 64Rivvy (see edit history) Link to comment Share on other sites More sharing options...
RivNut Posted January 5, 2020 Share Posted January 5, 2020 In 1964, the Riviera is the 4700 series. The Wildcat is the 4600 series and the Electra is the 4800 series. The Fisher Body Data plate on your firewall will show the model as a 4747. That translates to 4 = Buick 7 = Riviera 47 = 2 door hardtop. Because the Riviera has only one body style, there is just the one model for it, but body tags for a 1964 Wilcat could read 4639, 4647, 4667, or 4669 4=Buick 6=Wildcat, Then 39 = 4 door hardtop, 47 = 2 door hardtop, 67 = convertible, and 69 = 4 door sedan.

64Rivvy Posted January 6, 2020 Author Share Posted January 6, 2020 Thank you for clarifying. Now that I can be certain its the 4700 series that makes a lot of other diagrams I was referencing much more useful as well. Link to comment Share on other sites More sharing options...
64Rivvy Posted January 6, 2020 Author Share Posted January 6, 2020 (edited) Hey guys. One other question on this. The service manual shows the upper 3/4 hose coming off the firewall with a small loop. Is there a reason that loop is needed? I tried to replicate it but my heater hose just kinks and collapses when I try to make a loop that tight. Sorry just trying to get everything set back up as oem as possible. Thank you. I included a pic of the diagram I'm referring to. Raul Edited January 6, 2020 by 64Rivvy (see edit history) Link to comment Share on other sites More sharing options...
RivNut Posted January 6, 2020 Share Posted January 6, 2020 Thar was a custom molded hose specifically designed for that particular installation. It is not reproduced. I know of one Riviera owner who found radiator hose that had a wire molded into the length of it. He was able to replicate any bend without linking the hose. NO, I do not know what it's called or where he got it. Here's a picture from his build. I have heard that you can run your hose through a coil spring with an I.D. the same as the O.D. of the hose, bend it into the shape you want, and run really hot water into it and it will conform to the shape. Never tried it, just heard of it. Link to comment Share on other sites More sharing options...
64Rivvy Posted January 6, 2020 Author Share Posted January 6, 2020 Not too big of a deal. Just wasnt sure if there was any sort of science or reason to have that loop there. Figured there must be a reason. Thanks. Link to comment Share on other sites More sharing options...
RivNut Posted January 7, 2020 Share Posted January 7, 2020 Probably just to keep it flat against the firewall. The illustration you posted also shows you where the temp control valve sits. Don't forget that there is a bracket that goes between the inner fender and the valve. Link to comment Share on other sites More sharing options...
