Or should I call it a Cooling System pressure test on an "S". A 2003 MCS to be exact.
I have a Stant 12270 pressure tester and several adapters to fit various cars.
BUT.. the threaded cap on the plastic tank on the "S" is not among them.
Does anyone know the thread size on the MCS cap. Better yet, does anyone know the Stant adapter number to fit. Perhaps a/all late model BMW is/are the same?
BTW , Stant is of no use here, I tried.

Thanks
