Frequently in our big trucks, when a driver complains of the truck overheating and no heat, he is 2-3 gallons low on coolant. This is a system that holds about 11 gallons. The heater core is sometimes one of the higher or highest in the cooling system, and will sometimes be the last to receive coolant. Make sure you have the system bled completely.
