Abstract
An engine is provided with a cylinder block and a pump cover cooperating to define a volute chamber for a coolant pump. An impeller is connected to a drive shaft and positioned within the volute chamber. An insert is positioned within the volute chamber directly adjacent to a cutwater along a portion of the outer wall, with the insert positioned between the cutwater and the impeller. A method is provided where, in response to pre-determining a first coolant pump displacement, a first impeller is positioned within a volute chamber defined by a block and a cover. In response to pre-determining a second coolant pump displacement being less than the first displacement, an insert is affixed along the wall adjacent to the cutwater and a second impeller is positioned within the chamber.
