Another component important for the Chevrolet HHR is the Thermostat which as usual finds a place in the vicinity of the Radiator. Its major use is in maintaining the temperature of the engine to the right levels that will offer the premier performance. These are control devices that are used to sense the temperature and switch ON or OFF the heating or cooling appliances in houses, offices, and industries for climatic conditioning. Some of the older styles of thermostats used are the mechanical thermostats that include the bimetallic strip thermostats and wax pellet thermostats and pneumatic thermostats that employ the use of air-filled control tubes. These devices function by either turning on or off heating or cooling systems or in controlling the flow of heat transfer fluids to improve comfort and efficiency in Chevrolet HHR cars.
