Where to buy a new radiator cap

[Charlie Olson]

Hi, getting ready to drive PLYWOOD to CA, from AZ, to attend the 43rd Annual WAVECREST Woodie Meet and I want to replace the old rusty radiator cap. Where can I buy a replacement and what pressure pounds do I need, 4 or 7 pounds; or none? Thanks, Charlie, California or Rust!!!!

likely none. where is the over flow outlet??? If it is below the where the cap seals it really doesn't matter as no pressure can build. Try Tractor Supply or Farm and Fleet or what ever that type establishment in your area.

Charlie.......I got one of these non-pressure ones from NAPA...about $3 or

$4 as I recall. They didn't have it in stock, but got it from the warehouse

in a day or so.

The part number is ---

The over-flow outlet is at the very top of the radiator, not connected to the radiator cap water inlet; so, this must be a no pressure system. I did note that I have a nice six blade flex fan, which helps keep PLYWOOD cool. I'll try a few farm equipment stores, near here, thanks.

Thanks Bob, I'll go to NAPA in the AM. Really appreciate the help, Guys.
