Heating control valve, description Location of components See [Invalid linktarget] . Heating control valve
The valve regulates the flow of engine coolant in accordance with the set position of the heating temperature regulating switch. If setting the heating temperature high, the valve is opened to maximum coolant flow to the heater. If set to the cooling position, the flow of coolant is cut off. In case hot air is blowing when the heater is set to off position, a faulty heater valve will allow coolant to flow through the heater core. In this case, cooling efficiency will be significantly deteriorated. In summer, close the valve installed in the engine block to cut off the flow of coolant to the heater.
