These systems are pressurized, just like your car or truck. By increasing the pressure inside the closed part of the system, the boiling point of the coolant is enhanced. For every pound of pressure added, approximately 3° F can be added to your engine’s operating temperature, improving its thermal efficiency.

Who is responsible for draining the coolant hose?
