Heater Control Valve Temperature Control Assembly Replacement Service

What is the Heater Control Valve Temperature Control Assembly all about?

The heater control valve is located near the firewall in your vehicle. It controls the flow of coolant through the heater core, which is used to heat the inside of your vehicle. It is vacuum-controlled to open and close based on the driver’s input on the heater controls inside the cabin.

The entire heater control valve temperature control assembly works by means of the radiator, which disperses engine heat. When you turn on your car, the engine immediately begins generating heat from the friction in its various components and the engine cooling system activates. Heat has to move away from the engine in order to prevent the components from being damaged. The coolant absorbs that heat and moves it through the radiator, where it disperses into the air. The heater control valve simply diverts some of this heat into your car, and controls how much heat is delivered. When the heater control valve is set to high, you get more hot air.

Keep in mind:

  • Heater control valve assembly replacement is not part of your routine maintenance.
  • If your heater control valve isn’t working, the area near the firewall of your engine may overheat and engine components could be damaged.

Our recommendation:

If you turn your heater control knob and nothing happens, there is a risk of too much heat building up in your engine compartment. This can be devastating to sensitive engine components. You should have the problem checked out by one of our expert mechanics so that your engine cooling system will continue to work properly. It could be the heater control valve assembly, or something else in the cooling system.
