What is the car heater control valve?

New car heater valves Hamilton

The heater control valve is an important component of a car’s heating system. It controls the flow of coolant to the heater core, which in turn produces heat inside the cabin. It does this by opening and closing, limiting the flow of engine coolant to the car heater core in accordance with the requested heater temperature. Over time, the heater control valve can become worn or damaged, leading to a lack of heat or even overheating. That’s why it’s important to have it inspected and replaced as needed.

If you’re experiencing any of the following symptoms, it may be time to replace your heater control valve:

  • Lack of heat inside the cabin
  • Overheating
  • Leaks or drips of coolant
  • Unusual smells or noises coming from the heating system

Symptoms of a faulty car heater control valve:

Car heating not working correctly – A faulty car heater control valve may not be able to control engine coolant flow properly. This can result in your heater not always producing hot air, or hot air coming and going. If the car heater control valve is stuck open then the cars heater can put out air constantly, even in summer!

Heater not producing warm air – A broken heater control valve can permanently restrict the flow of coolant to the heater core. This prevents the air that passes through the heater core from becoming heated. This means you get no heat from your car heater in winter. 

Leaking coolant – A cracked or damaged heater control valve can result in engine coolant leaks occurring. When engine coolant leaks from your vehicle, the risk of your engine overheating increases. For this reason, it is important that coolant leaks are repaired quickly in order to prevent engine damage.
