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

Is there any visible leaks? Run the vehicle till its hot then let it idle over a dry spot in a garage and wait for water to appear if after 10 mins nothing turn it off pop the hood and wait and keep looking, does it poor out of the coolant resevoir?

Do you notice excessive white exhaust?
