Abstract
The present disclosure relates to a coolant system to cool an engine assembly. The coolant system includes a coolant pump impeller with multiple concentric ribs extending axially on a first side of the coolant pump impeller and multiple vanes extending axially on a second side of the coolant pump impeller. The coolant system also includes a coolant rail to collect coolant from a water jacket that surrounds portions of cylinders and a cylinder head of the engine assembly. The coolant system further includes bleed fittings to remove trapped air as the coolant system circulates coolant through the engine assembly. First and second bleed fittings are provided on opposite corners of the engine assembly such that either the first or the second bleed fitting is at a highest point of the coolant system based on an engine orientation of the engine assembly.
