It may never overheat at lower speeds because it is not working as hard as it does at higher speeds. A closed thermostat will not allow enough coolant to reach the engine to cool it. If you’re only overheating on the highway, you might just replace the thermostat (especially if you’re driving an older vehicle).
Why is the radiator not opening on my Toyota?
