In the next few years, front end vehicle design will have to be profoundly modified in accordance with the pedestrian crash test specificatons. The height of the cooling module at the front end should be reduced in order to increase the free space requested between the top of the cooling module and the hood. Today there are more and more heat exchangers located at the front end and vehicles are equipped with higher and higher powered engines. The engine cooling module becomes a big problem of packaging at the front end due to the reduced space available. Ultimate Cooling TM system is a new engine cooling system concept for solving this packaging problem. This new system uses only one fluid, that is water (coolant), to cool all the engine fluids, that means: a CAC(charged air coole) becomes a WCAC (water cooled charge air cooler), an air CDS (cooled condenser), becomes a water cooled WCDS (condenser), an engine OC (oil cooler) or a transmission oil cooler or a hydraulic oil cooler ( oil to air), becomes a water cooled oil cooler WOC), a FC ( fuel cooler) (fuel to air), becomes a WFC (water cooled fuel cooler) .These new heat exchangers will be moved from the front end to the under hood. At the front end there is only one multi-temperature radiator providing high temperature and low temperature on demand. Thus the packaging problem could be solved. A UltimateCoolingTM system application on the NISSAN XTRAIL vehicle equipped with the turbo gas line engine, leads to modify the cooling system in a similar manner. A CAC loated on the top of engine becomes a WCAC installed at the same place but smaller, a conventional CDS condenser at the front end, becomes WCDS and fitted in the engine compartment, an in tank TOC (transmission oil cooler) becomes an external TOC. At the front end, the two heat exchangers, radiator and A/C condenser, have been replaced by only one multi-temperature radiator. Important packaging reduction of front end module has been obtained by 38 %. Concerning the global system of engine cooling, packaging reduction remains important which is up to 42%. The new coolant architecture of UltimateCoolingTMbased on XTRAIL, new components WCAC, WCDS and TOC, engine cooling and A/C perfomance were tested succesful in the climatic wind tunnel and on road.
