Radiator cap part number?

Unread post by mutt and jeff » March 13th, 2022, 1:11 pm

Delivering a A2 to it's new owner tomorrow and went to check the coolant and the radiator cap came off in three pieces in my hand. I know the vendors have the correct one if he wants to order one. I just hate to turn it over to him this way. Anyone got a modern civilian like NAPA or O'Reillys part number so that I can possibly pick one up today or in the morning?

I'll hang up and listen.

NAPA part number above confirmed. The one they gave me today a hexagon shape top, although online I saw the same part number having the round top like the stock one.
