2. Thermostat
• Thermostat is a small and neglected part of a car. However, it performs an
important function by controlling the temperature of the engine coolant valve.
Thus, when it stops functioning, the car engine can get overheated and does
not work anymore. Thus, once this thermostat begins to wear out, it should
be replaced without much delay.

3. Thermostat’s Function
• The thermostat starts at a closed position when you start the engine to help it
reach operating temperature. As coolant temperature rises, it begins to open.
The opening allows hot coolant in the engine to flow into the radiator, while
the water pump pushes lower-temperature coolant from the radiator into the
engine. When the lower-temperature coolant reaches the thermostat
container, the expanding fluid begins to contract, closing the thermostat’s
valve.
• During engine operation, though, the thermostat actually never fully closes or
opens, but gradually nears either state to control coolant flow, depending on
engine operating conditions. This allow the engine to operate at the best
temperature. This ideal engine-operating temperature accomplishes several
goals: It helps engine oil to lubricate efficiently and to remove harmful
deposits. It reduces emissions and gas consumption and contributes to
engine performance. Thus, the thermostat has an impact on your engine's
health and longevity.

4. What are the symptoms of a stuck open
thermostat?
Symptoms of a stuck open thermostat are slow to reach normal operating
temperature and only warm air blowing from the heater. Symptoms of a stuck
closed thermostat are engine over-heating and radiator boil-over. Yes, they
can stick open or closed.
Time how long it takes the engine to warm up enough to produce heat when
the heater is turned on. If it takes more than five minutes for the heater to
produce heat, it is a sign that the thermostat is stuck open, allowing all the
coolant to flow all the time.

5. What is a thermostat housing?
• The main purpose of a thermostat housing is to contain the engine
thermostat and provide a coolant outlet to the radiator. In some cases, each
radiator hose will be connected to a similar looking housing, with one serving
as a coolant inlet and the other as an outlet.
