Water Pump - GM LS Eng. Corvette/G8/CTS 04-09

The Water Pump - GM LS Eng. Corvette/G8/CTS 04-09 from MELLING is a direct-fit replacement cooling system component engineered for Chevrolet Corvette, Pontiac G8, and Cadillac CTS models equipped with LS-series engines. This mechanical pump maintains optimal coolant circulation, preventing engine overheating and thermal stress during highway driving and track conditions. Built for OEM-level reliability, it addresses cooling system failures that compromise engine longevity and performance in these high-performance platforms.

Constructed from aluminum with a natural finish and fitted with a black pulley, this pump features a 4.73-inch hub height that maintains proper serpentine belt alignment and drive ratio specifications for LS engine families. The mechanical design ensures consistent flow rates across engine load ranges without electronic complexity, reducing failure points and extending service intervals. Aluminum construction provides thermal conductivity and lightweight durability while resisting corrosion from coolant chemistry and extended fluid drain cycles typical of modern engine management.

Owners of 2004–2009 Corvettes, G8s, and CTS models with LS powerplants benefit from this OEM-replacement unit when addressing cooling system maintenance or failures. Installation requires standard mechanical knowledge and basic hand tools; the pump bolts directly to factory mounting points without modification. Technicians and enthusiasts performing engine rebuilds, water pump service, or preventive cooling system upgrades will appreciate MELLING's reputation for precision-engineered flow characteristics and durability in demanding LS engine applications.
