Concorde V6-2.7L VIN V (2001)
Thermostat: Description and Operation
DESCRIPTION
The thermostat on the 2.7L and 3.2/3.5L engines are located on the lower left side of engine, near the front and. The thermostat on both engines are on
the inlet side of the water pump. The thermostats have an air bleed located in the thermostat flange. The air bleed allows internal trapped air during
cooling system filling to be released.
OPERATION
The engine cooling thermostat is a wax pellet driven, reverse poppet type. The thermostat is located in the inlet side of the engine to provide fast warm
up and to optimize a consistent temperature in the engine. The thermostat is designed to prevent leakage through it and to guarantee a minimum engine
operating temperature of 82°C (180°F). They also automatically reach wide open at a temperature of approximately 95°C (203°F) 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 102°C (215°F) the coolant temperature
is controlled by the radiator, fan, and ambient temperature, not the thermostat.
