Sebring Convertible V6-2.5L VIN H (1997)
Thermostat: Description and Operation
LOCATION
The engine thermostat is located in a thermostat housing, located below the throttle body.
GENERAL INFORMATION
This thermostat has an air bleed valve, located in the thermostat flange. The engine cooling thermostats are wax pellet driven, reverse poppet
choke type.
PURPOSE
They are designed to provide the fastest warm up possible by preventing leakage through them and to guarantee a minimum engine operating
temperature of 88 - 93°C (192 - 199°F). They also automatically reach wide open so they do not restrict flow to the radiator as temperature of the
coolant rises in hot weather to around 104°C (220°F). Above this temperature the coolant temperature is controlled by the radiator, fan, and
ambient temperature, not the thermostat.
OPERATION
The thermostat is operated by a wax filled container (pellet) which is sealed so that when heated to a predetermined temperature. The wax expands
enough to overcome the closing spring and water pump pressure, which forces the valve to open. Coolant leakage into the pellet will cause a
thermostat to fail open. Do not attempt to free up a thermostat with a screwdriver.
