What is the Heater Control Valve all about?

The heater control valve is one of the many components that are responsible for warming the interior compartment. This valve controls the flow of coolant from the engine to the heater core. Most heater control valves are operated in three basic ways. A manual cable, a thermostat type system, or even engine vacuum can control them.

Keep in mind:

  • The heater control valve cannot be repaired, only replaced.
  • When the valve is replaced, a mechanic should inspect the other heater hoses, so that they can be replaced if need be.
  • If the heater control valve is contaminated or corroded, the coolant in the system should be flushed when the new valve is installed.

How it's done:

  • Pressure check the cooling system.
  • Test operation of the valve.
  • Replace the control valve if bad/leaking.
  • Fill with coolant.
  • Test operation of the heater.

Our recommendation:

Since the air and heating system is a closed system, a mechanic won’t be checking your heater control valve during routine inspections and services. Instead, keep an eye on your air and heating system, and schedule an inspection if you notice that anything is malfunctioning. If your heater either doesn’t work or won’t adjust, then you possibly have a malfunctioning heater control valve, and you should schedule an inspection.

What common symptoms indicate you may need to replace the Heater Control Valve?

  • Coolant is leaking.
  • Heater does not work.

How important is this service?

If the heater control valve is leaking then you will end up with a loss of coolant, which will eventually cause the car to overheat. A properly working heater control valve ensures the proper functioning of the heating and AC system.

Lexus GS400 V8-4.0L - Inspection / Diagnostics - Los Angeles, California
While AAA essentially diagnosed and fixed the (immediate) problem with my vehicle, Chris followed up with a more thorough inspection of my engine, brake pads, and tires. There is only so much you can check on without the car being pulled to a station or a shop, however Chris did ALL that he could while he was there servicing my vehicle. Aces across the board!

Lexus GS400 V8-4.0L - Alternator - Jenks, Oklahoma
After having my car sit in my garage for a month with a dead alternator, I found yourmechanic.com, and more specifically, Nathan Thorne. YourMechanic.com's website was super easy to use, they already had the repair I needed in their system, gave me an exact quote, and let me pick when the repair was going to happen. Now the best part. When the mechanic came out, he determined that the repair was going to take significantly longer than they had quoted...AND DIDN'T UPCHARGE ME. He just did the repair and said since the company's quote on the time for the repair was wrong, he would just deal with them. Couldn't have asked for better service and will definitely recommend and use Nathan Thorne again.
