HKT Thermostats

About Thermostats

A thermostat works to keep the engine coolant at the right temperature.
As soon as the engine coolant reaches the specified temperature, the valve on the thermostat opens or closes due to the expansion or contraction of the wax element.
Opening and closing of the valve allow to control the flow of engine coolant between the engine and the radiator to keep the temperature properly inside the engine.
It helps to improve fuel efficiency.
