GM LS Water Pump - Mid Mount Acc. Drive

The GM LS Water Pump - Mid Mount Acc. Drive from Holley is a precision-engineered cooling system component designed for General Motors LS-series engine platforms. Built for operators and technicians who demand reliable thermal management in high-performance and stock applications alike, this mechanical water pump assembly delivers consistent coolant circulation under demanding conditions. Whether you're rebuilding a vehicle for duty use, competition, or field operations, this bolt-on unit integrates seamlessly into existing LS engine architecture without requiring complex modifications.

Manufactured from aluminum for lightweight durability and finished in black paint for corrosion resistance, the mid-mount accessory drive configuration positions the pump for optimal belt routing and clearance in tight engine bays. The mechanical drive system eliminates electronic dependency, ensuring operation remains unaffected by electrical fluctuations—a critical advantage in tactical vehicle builds, remote deployments, or vehicles operating under extreme thermal stress. At 3.77 lbs and compact at 4.9 x 4.9 x 6.4 inches, this assembly balances functional displacement with installation accessibility, allowing technicians to work efficiently without excessive repositioning of adjacent components.

LS engine builders, fleet maintenance personnel, and specialty vehicle operators benefit most from this proven cooling solution. Compatible with virtually all LS-series variants—including LS1, LS2, LS3, and LS7 platforms—the bolt-on design minimizes downtime during installation or replacement. Proper fitment requires verification of your specific engine block and accessory configuration; consult technical documentation or Holley's application guide before purchase to confirm mid-mount orientation aligns with your belt drive setup and available clearance.
