Howdy all! I hope everyone is well and safe.

I'm looking for advice for a replacement radiator cap for my 250 - preferably one that has both outflow and inflow, since my overflow bottle has been, well, overflowing!

Thanks!

B.
 
The radiator cap does not have any 'inflow/outflow'. There is a small tube that exits the side of the filler tube and is connected to the overflow bottle. It is the pressure or vacuum in the cooling system that determines which direction the coolant flows. Unless your car is modified TRF, Moss, or others should have the proper cap for your 250, pretty sure it is 13lb.
