    1. Water Pump Assembly


      1. An electric water pump, which operates in response to ECM signals, regulates the coolant flow volume, thus, the warm-up performance is further enhanced as well as reducing the cooling loss.

    2. Cooling Fun


      1. A ring type cooling fan is used. In addition, swirl generation is reduced by enlarging the fan feather edges and thus fan noise has been reduced and cooling ability has been optimized.
