ABSTRACT:
A heating and pressurization system for a liquid-cooled engine having a cooling system is provided. The heating and pressurization system includes a coolant circulation and pressurization system comprising a coolant tank, a coolant pump receiving coolant from the coolant tank through a manifold, a coolant outlet conduit, and a coolant inlet conduit. The coolant outlet conduit and coolant inlet conduit each have an end which has a double dry break quick disconnect coupling which is detachably fixable to the cooling system of the engine and to another double dry break quick disconnect coupling attached to the coolant tank though an access passage. An immersion heater is incorporated into the coolant circulation and pressurization system which is operable to heat coolant circulating therein. The coolant pump is operable to circulate coolant at a constant pressure through the coolant circulation and pressurization system and the cooling system of the engine when the coolant outlet conduit and the coolant inlet conduit are detachably fixed to the cooling system of the engine.
