Hi brand new to the forum so il start with saying hi.
I've just bought a japspeed radiator for my 2004 impreza wrx and my question is the new radiator comes with a new cap marked 1.3(bar I'm guessing) so does that mean I have to renew my header tank cap?or is that 1.3 too?or does it not matter?
I just don't want the garage to call up with a problem and delay the fix.

Thanks in advance

Jason.
