WHY IT OVER HEATS IF I DRIVE 120KM/HR OR ABOVE

1997 Subaru Legacy • 243,000 miles

If I drive under 100 km/hr I have no problem the only problem is when it comes above. I change the thermostat from the dealer it went well but on hwy it is somthing diferent

Have checked physically that you are actually overheating or just basing yourself with the gauge? Such as boiling when you pull over-if not could be low on coolant, water pump impeller and coolant temperature sensor

If you are losing heater output ( heater on vents blowing cold ) when car is overheating stop looking and find someone to do your head gaskets.
