• The water pump impeller diameter has increased in size to 100 mm from 90 mm.
• The larger impeller will increase coolant flow through the engine which will offset higher heat rejection.
• Note: Both water pumps have the same bolt pattern, but a different sealing area.
As a result, the smaller water pump has the physical ability to be installed into an updated front cover. If this is done, a coolant leak and over heating of the engine may result.
