Abstract
A cooling system for a water cooled internal combustion engine for a vehicle includes an engine body having a water jacket therein. The system comprises a radiator and a pump chamber. The pump chamber is in communication with the water jacket. A water pump creates a flow of water into the water jacket. A first main conduit has an end connected to the water jacket at the engine outlet and another end connected to the radiator. A second main conduit has an end connected to the radiator and another end connected to the pump chamber. A reservoir tank is arranged at a position more elevated than the radiator, and a supplementation conduit connects a bottom portion of the reservoir tank with an upper part of the pump chamber. A thermostat valve is arranged between the second main conduit and the pump chamber at a position upstream from a location where the supplementation conduit is connected to the pump chamber. A check valve is arranged in parallel with the thermostat valve and allows the introduction of air from the pump chamber to the second main conduit while preventing a flow of the air from the second main conduit to the pump chamber. The check valve is in a normally closed positi…
