Hi guys,
My 2013 2.5l Outback has been overhating, and every time I stopped to let it cool I noticed the coolant is spilled back into the plastic reservoir. Liquid is boiling inside, bubbling though the lower hose coming out of the engine is cool, so it seems there's an air lock blocking coolant. I initially had a new thermostast put in but that dind't fix it, then got a whole new radiator installed but it seems the problem is the head gasket and so now I need to decide whether I want to spend +-4k to fix it. The car is actually in good shape other than that, and it has donw just a bit over 50.000km to date. I am not much experience with the head gasket fix though, if there's a relatively high chance of that fixing the problem for good or I should be contious that even after doing it the problem could stil persist.
If anyone can share their experience, I'd really like to hear your opinion if spending +-4k on a car that 17k seems worth the risk?
