What does a heater tap valve do?

• The purpose of the Heater Control Valve is to regulate the flow of coolant to the heater core. In the off position the heater valve blocks coolant flow to the heater core hence when no heating is required and the reverse when heating inside the vehicle is needed

 

What happens if you bypass the heater control valve?

• Your heater control valve works to deliver heat from the engine to the passenger cabin of your car, and if it has been bypassed, then the cabin will not receive heat. Instead, it will be dissipated by means of the bypass hose

 

How do I know if my heater control valve is working?

• Common signs include the heater not working, coolant leaking from under the engine, and no voltage across the heater control valve

Will a bad heater control valve cause overheating?

• A coolant leak at the heater control valve is not only a problem in that it will disable the heater, but it will also compromise the cooling system which can cause the engine to overheat
