An engine water pump assembly which is driven by the back side of the fan and generator V-ribbed belt has been adopted.
The volute chamber for the engine water pump assembly is integrated into the timing chain or belt cover sub-assembly, achieving a compact design. Additionally, the thermostat housing is integrated into the timing chain or belt cover sub-assembly, simplifying the water passages.
