Water Pump - LS Engines 5.7L/6.0L/6.2L 04-09

The Chevrolet Performance Water Pump for LS engines is a mechanical, aluminum-bodied cooling system component engineered for 5.7L, 6.0L, and 6.2L displacement engines produced from 2004 to 2009. As a factory-backed replacement and performance upgrade option, this pump maintains OEM reliability while delivering consistent coolant circulation under demanding conditions—whether in stock applications or high-output modified builds where cooling efficiency directly impacts engine longevity.

Built in aluminum construction, this pump features a 3/4-inch pilot bore for secure mounting to the engine block and belt-drive system. The natural finish resists corrosion while the mechanical design ensures predictable performance across temperature ranges without electronic complexity. At 12.63 pounds, the unit integrates seamlessly into the factory cooling system layout, making it suitable for both OEM restoration and performance platform builds where thermal management is critical for sustained power output.

This pump serves LS engine enthusiasts performing cooling system maintenance, rebuilds following engine modifications, or complete platform swaps. Buyers sourcing parts for 2004–2009 Chevrolet trucks, Corvettes, and performance vehicles with LS-series powerplants will find this an OEM-backed solution that maintains factory specifications and fitment. The part number 12710208 ensures correct application for your specific engine displacement and model year.

LS-series engines are known for efficient cooling architecture, and maintaining proper coolant flow with factory-approved components protects against cavitation, hot spots, and overheating under load. Whether replacing a worn original pump or upgrading from an aftermarket alternative, choosing a Chevrolet Performance pump ensures compatibility with existing hose routing, belt tension settings, and thermal dynamics calibrated for these specific engines.
