people

I have. 2.5 wagon wrx 2006



So the temp gauge went up the other day after a bit of a blat, car is on 116000m

It had filled the plastic expansion bottle(one next to the rad)

Any way refilled the system as we empty.

Driving gentle it was fine give it some boost same happens.

So properly burped the system put expansion on the low level

Took for a 20mile drive it was perfect not using boost.. Only put a little in the expansion tank basically as it should

Then used boost again got home it started heating up lots air on system and plastic expansion tank was filled to the brim..



;(

Headgasket I'm guessing.. As it works same way as my old mr2..

Anything also possible bit I really can't see it



Thanks
