Ok Adam that has mad some sense ill try that cheers

By passing coolant im meaning it's leaking past the rad cap and coming out the over flow. I have been topping up the expansion tank every few weeks

Hi folks I have a issue with my wagon it is passing coolant from the radiator cap overflow. It has a large alloy mishimoto radiator dosent overheat and runs fine, I thought it might of been a weak spring in the cap so I replaced it the other thing I was thinking was maybe head gaskets?? Is this a common fault for subaru? ?
