Dbolter Posted February 9, 2018 Report Share Posted February 9, 2018 Hello I am coming up short finding a replacement radiator cap for my '38 Chrysler.... I know I am just not looking in the right place.... Nothing on eBay, and andy bernbaum doesn't carry it. One year only deal?/? Orderded one from Vintage American Parts, and it is not correct.... Any Thoughts Gentleman? Thanks ~dbolt Quote Link to comment Share on other sites More sharing options...

busycoupe Posted February 9, 2018 Report Share Posted February 9, 2018 (edited) Your cap appears pretty solid. Why don’t you clean it up on a wire wheel, paint It, and put a new gasket on it. It doesn’t have to hold pressure, the old cooling systems were’nt pressurized. Edited February 9, 2018 by busycoupe 1 1 Quote Link to comment Share on other sites More sharing options...
desoto1939 Posted February 9, 2018 Report Share Posted February 9, 2018 (edited) You might need either a R-1 or R-2 cap. The r3 fits my 1939 Desoto.

Unfortunately, it's full of R-2's. Quote Link to comment Share on other sites More sharing options...
Dbolter Posted February 10, 2018 Author Report Share Posted February 10, 2018 Thanks for the replies... I wasn't aware of the R1 thing. Have a sweet weekend! ~dbolt Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted February 10, 2018 Report Share Posted February 10, 2018 maybe not in your price range but definitely available https://www.ebay.com/itm/37-38-Chrysler-Dodge-DeSoto-NOS-NEW-Stant-EVRSEAL-UNDERHOOD-RADIATOR-CAP-R1/311129617980?hash=item4870c5363c:g:XvIAAOxyzy1ST6aC&vxp=mtr Quote Link to comment Share on other sites More sharing options...
dpollo Posted February 11, 2018 Report Share Posted February 11, 2018 A fuel tank cap will fit. I used one on my 37 Plymouth until the correct cap came along. The jaws of the Plymouth fuel cap are not as wide. I think I used a Ford item. 1 Quote Link to comment Share on other sites More sharing options...

I would wire wheel, then bead blast. Paint with Rustoleum Rusty Metal Primer, then Rustoleum black paint. Will look brand new for not much money. Don’t forget a new gasket. If no bead blaster is available, soak in vinegar after wire wheeling. Quote Link to comment Share on other sites More sharing options...

It can be applied without a primer and the hammer finish disguise slight irregularities in the surface. I used black, but it comes in several colors.
