Higher water temperature of sedan engine may lead to engine over-heat, power reduction and fuel consumption increasing. This problem must be resolved in the phase of engine development. The main reason of high water temperature is detected from the point of cooling system components performance analysis and test scheme design is conducted. The difficult problem of higher water temperature is effectively resolved by modifying thermostat opening temperature and lift. It points out the solution for trouble removal of engine cooling system.
