Abstract
A cooling system for an internal combustion engine with an intercooler has a pump with a single drive shaft which drives two sets of vanes. One set of vanes circulates coolant through a circuit including the engine block, and the other circulates fluid through a circuit including the intercooler. Around the rotary impeller of the pump is a clearance to allow communication between the circuits. Thus, the intercooler can function as an intake air heater when cold-starting the engine, idling without supercharging, or operating the engine in the region of low engine rpm's.
