1. A method of using an engine cooling system with a bus including a rooftop and an engine in an engine compartment for propelling the bus, the engine including one or more passages for allowing coolant to flow there through for cooling the engine, the method comprising:
- providing a horizontal rooftop engine cooling system including an electrical heater unit and one or more radiator units having a horizontally mounted radiator through which coolant fluid flows for removing heat from the radiator, one or more fans disposed above the radiator to assist in removing heat from the radiator;
horizontally locating the rooftop engine cooling system on the rooftop of the bus and the electrical heater unit located outside the engine compartment;
interconnecting the one or more radiator units of the rooftop engine cooling system to the one or more passages of the engine to allow coolant to flow between the engine and the rooftop cooling system to cool the engine;
pulling air from the radiator with the one or more fans in the same direction as the natural convection of the radiator to assist natural convection; and
electrically heating coolant in the rooftop engine cooling system with the electrical heater unit.
