Nothing is as simple as I think. Not even radiator caps. I had some reward money about to expire so I ordered a “Murray 1002-05” 4 PSI cap from the O’Reilly. It arrived as a Motorad by the same part number.
Brought it home last night and it’s too “deep” to work. Can’t twist the cap shut because the pressure apparatus bottoms out before the tabs on the cap can reach the radiator flange and twist shut.
Anyone have a known modern part number for a 4 psi cap that works on a stock AD radiator? Poking around on RockAuto, I’m thinking that a Motorad T4 might fit.
