M3 radiator cap needed
« on: May 21, 2026, 07:11:16 PM »
 I’m in need of a radiator cap for the radiator.
Even if a cap is vented, if it fits I figure I can unvent it.
I can’t seem to find a part number for one that will fit.
Any suggestions are appreciated!

This is the cap that our museum halftrack has and works fine.  You can get it at Staman, Joe's Motor Pool, Wildenberg, etc. if in Europe.  Not sure about a source in the US though.
