This how it happened i changed the hoses,coolant and themostat because the car was getting a little too hot this was during october it still was hot in my area so i was running the a/c,but when it turned cold i tried the heater nothing came out but cold air.....i changed the radiator because it ran hot again with the new thermostat,coolant and hoses,the shop i took it to sent it to a radiator shop and found out the old radiator was stopped up,another guy said that the heater control valve was probably bad,i checked both heater core hoses and both are getting hot,is the heater control valve and actuator the same thing?
