A coolant pump for an engine includes a pump case main body and a pump drive shaft journaled therein. The pump drive shaft has a plurality of blades mounted thereon and is rotatable about a pump drive shaft axis. The coolant pump also includes a partition member and a lid. The partition member and the pump case main body define a pump chamber configured to house the blades. The partition member also defines a pump chamber inlet port. A fluid inlet chamber is defined by the partition member and the lid. The fluid inlet chamber provides fluid communication between a fluid inlet port and the pump chamber inlet port.
