Where Is the Thermostat in an Escalade?

Save

Locating the thermostat in your Cadillac Escalade requires some basic knowledge of the heating/cooling system of the vehicle. Replacing a defective thermostat is an easy, low-cost endeavor if you have automotive-repair experience.

Cooling System

  • The cooling system keeps your engine from overheating during operation by opening and closing a temperature-sensitive valve in response to changing coolant temperatures.

Radiator

  • The radiator -- a large, rectangular-shaped part -- sits behind the grill at the very front of the Escalade's engine. Radiators and heating/cooling systems of recently driven vehicles can be hot; let the engine cool for at least three hours before touching it.

Upper Radiator Hose

  • At the top of the radiator, a large rubber hose leads out towards the engine, to carry radiator fluid to the engine block.

Thermostat Housing

  • As the upper radiator hose meets the engine block, a dome-shaped housing contains the thermostat. You cannot actually see the thermostat until you remove the housing.

Considerations

  • Don't confuse the heating and air conditioning system for the thermostat. You'll find temperature controls for the interior of the vehicle -- correctly referred to as the climate controls -- on the dash. For a detailed diagram showing the thermostat's location, purchase the factory service manual for your year and model Escalade.
