Replacement Radiator Cap Source

Recommended Posts

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

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.

You might need either a R-1 or R-2 cap.

 

The r3 fits my 1939 Desoto.

Start searching for R-1 or R-2 radiator caps on ebay

This old Stant Everseal box shows an R-1 radiator cap as correct for a 1938 Chrysler. Unfortunately, it's full of R-2's.

Thanks for the replies...  I wasn't aware of the R1 thing.  Have a sweet weekend! ~dbolt

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.

Several ways to clean this up. 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.

I used Rustoleum hammer finish spray paint.  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.
