I've changed out my heater core and thermostat in the truck, fan blows hi but no heat, checked hoses coming from core both are still cold, their is no valve, one of my hoses comes from heater core to engine the other from the heater core to the radiator, i've looked on the water pump to see if there could be a connection for that hose but their is not, any help would be appreciated, I would like to get my heater working. Its a 1989 k1500, with a 1995 5.7L engine in it, with a digital heater/ac unit, i've even checked the actuator and the blend door-they are operating, changed out the thermostat and the heater core, I have one heater core hose coming off the right side of the heater core going to the engine and the left hose going to the radiator, both hoses are cold to the feel with the engine running and the heater on high, i've filled the coolant level up, but dont get any heat with the controls on high. Ive also checked for a valve in the dash and in the engine compartment and I do not find one. I would like to get the heater working.
have the same problem?
