Thermostat: Description and Operation
ENGINE COOLANT THERMOSTAT
DESCRIPTION
CAUTION: Do not operate an engine without a thermostat, except for servicing or testing.
A pellet-type thermostat controls the operating temperature of the engine by controlling the amount of coolant flow to the radiator. The thermostat is
opened when the engine temperature reaches 195°F (90°C). When opened, the thermostat allows engine coolant to flow to the radiator. This provides
quick engine warm up and overall temperature control.
The same thermostat is used for winter and summer seasons. An engine should not be operated without a thermostat, except for servicing or testing.
Operating the engine without a thermostat can cause the following problems:
^
Longer engine warm-up time
^
Unreliable warm-up performance Increased exhaust emissions Crankcase condensation
This condensation can result in sludge formation.
OPERATION
The wax pellet is located in a sealed container at the spring end of the thermostat. When heated, the pellet expands, overcoming closing spring tension
and water pump pressure to force the valve to open.
