Instead, there are typically markings for cold and hot on the edges of the gauge and a normal range in the middle. In most cars, the temperature needle will be at or near the center when the engine is at normal operating temperature, which usually takes at least a minute or two to reach after starting a cold engine.

Can a stuck thermostat fix itself?

When the thermostat becomes stuck, it is reasonable to simply replace it. Also, when the thermostat housing is removed, the housing gasket should be replaced even if you’re just checking it. A housing gasket needs to be able to seal fully, and it won’t if it’s been used.
