Question about 2004 Dodge Ram 1500
Changed radiator, thermostat, and hoses. No heat inside truck(2002 Dodge 1500 4.7l). Both hoses going into heater core are hot. Top radiator hose is hot. Bottom radiator hose is ice cold. Truck does not overheat. Why no heat?
Why was radiator replaced?Did it have heat before ? If it was plugged, the heater core may also be plugged. Try flushing it with a water hose in both directions. I dont know why the botton radiator hose would be cold, the radiator should be a uniform temp and the air coming through the radiator should be HOT, when the engine is at operating temp. What condition was the old coolant? if it was rusty, the water pump may have lower flow than normal.
