Hello.

Recently I have changed radiator and now would like to change radiaotor and filling tank cap's. What preassure (bar) I should use for radiator and for filling tank?

Thanks in advance!

1.1 bar is fine for a classic

Shouldn't this be in technical? Or are you looking to get the rad cap "mapped" ... lol

The std rad and pressure caps are fine, after market rads are generally less efficient than the Subaru original. So keep an eye on your coolant temps, but the dash gauge reads the same from 60 degrees to 106 degrees so if it moves even a little you should be aware you have a possible big problem.

cheers

My fault... Wrong topic

I have rebuild orignal rad with aluminium header... (or how it's called). I just thought to change new caps.
