2016 Subaru Outback 2.5i CVT Premium with HK
Guys need help my subbie outback 2016 2.5 is overheating when I drive above 90mph. The temp guage is normally on the middle but when I drive fast it starts to creep to the right side at the 3/4 close to the red zone. I have checked the radiator and have noticed that coolant is moving from the radiator to the reservoir tank after a drive. The car is not losing coolant, if I remove the reservoir tank and pour the coolant back into the radiator it fills the radiator and the reservoir tank remains with the quantity between the min and max. Is it a head gasket issue? Or thermostat or the radiator cap. The car is still new less than 40k miles. If i hook up an obd the coolant temp is around 109 degrees celcius when driving around 80mph. If I push it to 90 or 95mpg it goes to 110 degrees celcius. Thats when the temp gauge starts to move to the redline although i have not allowed it to reach the redline .Have removed the thermostat and drove it without but it still does the same.
