Car overheats when under extreme load: going uphill, hot weather. AC makes it worse but happens even without AC. I tried to fix this by replacing the coolant and using the Subaru coolant conditioner, but it still overheats. Possibly head gasket on its way out? The problem is rare enough that I have chosen to live with it.
