How much coolant is it using? What color is the exhaust smoke? Could be a head gasket, but also it will send compression into the radiator. Sometimes you can take the overflow hose and put it into a bucket of water and you can see the bubbles. The evaporator/heating core could leak thats in the top of the cab but you would see coolant on the floor if the drains are clean.
