Patent ID: 7263954

Claim:
A cooling system for an internal combustion engine comprising a pump to circulate coolant through the engine, a radiator to cool coolant passing therethrough, a thermostat controlled bypass valve located between a coolant outlet from the engine and an inlet to the radiator to selectively allow coolant to flow through the radiator or bypass the radiator and flow back directly to the pump depending upon the temperature of the coolant flowing through the bypass valve and at least one electronically controlled flow control valve located between the coolant outlet from the engine and an inlet to the bypass valve to control the flow of coolant passing to the bypass valve, and the system further comprising a degas reservoir to remove gas from the coolant circulating through the cooling system, the degas reservoir being connected at one end to the cooling system at a position between an outlet from the or each electronically controlled valve and an inlet to the bypass valve and begin connected at an opposite end to a inlet conduit to the pump.
