my vehicle is overheating, ive literally done everything except change the heater core and heater control valve. Ive changed the water pump, radiator and hoses and the thermostat. I have drained the the system and back flused the inlet and outlet hoses that connect at the fire wall and ive tried back flushing the heater core, yet its still overheating.
where is the heater control valve located in my mercury villager? on 1999 Mercury Villager
