Hello Bob and Ken,
My van has been overheating. I have changed the heater core, thermostat, water pump and radiator hoses. The overheating still continues to happen. I also have to keep filling the radiator 2 to 3 times a day with water and coolant. It usually takes approx. 2 gallons each time I fill it. I have not changed the radiator. Could this be the problem? I am also not getting any heat.

thanks Stacy
