ABSTRACT:
An engine pressure-vacuum cooling system with a horizontal coolant storage tank wherein the cooling system is pressurized during engine operation and maintained under vacuum when the engine is inoperative. After filling the system with coolant, during the initial engine warm-up cycles air is purged through a one-way valve and the cooling system thereafter sealed against further entry of air. The storage tank includes a means for confining sludge and other debris to the tank and a means for warning when the system vacuum exceeds a pre-determined level.
