Abstract (en)

[origin: EP0905357A2] A liquid cooling system for an IC engine (2), with the radiator (5) at a lower height than the engine thermostat (4) has a pressure control line (13,13') between the thermostat and the radiator to vent any trapped air back into the radiator. The top of the radiator is connected to the bottom of the header tank (10) by a pressure compensating duct (11) and hence any trapped air is eventually ducted to the header tank, from where it is vented by a pressure relief valve (17).
