Moroso GM LS Series Electric Water Pump - Billet Aluminum

The Moroso 63566 electric water pump is a billet aluminum unit designed for GM LS series engines. It mounts directly to the stock water pump location, offering a compact and cost-effective alternative to bulky stock water pumps. It eliminates the drive belt to save horsepower and provides maximum circulation for cooling efficiency, especially at idle. It is compatible with both 12 and 16-volt systems, drawing 8-10 amps in a typical 12V system, making it suitable for drag racing applications without an alternator. The installation requires a remote thermostat housing (e.g., Moroso part #63425 or #63426). It can also be used in conjunction with the Moroso #63836 Alternator/Vacuum Pump Mount. This product contains a chemical known to the state of California to cause cancer, birth defects, or reproductive harm (Prop 65 Warning).
