Four Seasons HVAC Heater Control Valve P/N:74610
Four Seasons 74623 heater control valve for the 1984-1987 Honda Civic and other vehicles is a valve that regulates coolant flow to the heater core.
A heater that stays cold, heat that won't change with the control, coolant leaking at the valve or a cable that sticks can point to a failing HVAC heater control valve. A stuck thermostat, a clogged heater core or low coolant can be behind these signs too, so find the cause before you buy a valve.
It also fits the 1986-1989 Acura Integra and the 1986-1987 Honda Wagovan, with one valve per vehicle.
