LS-1 Electric Water Pump - Black

The MEZIERE LS-1 Electric Water Pump in black is a complete cooling system solution designed specifically for GM LS-series engines. This 100-series electric water pump delivers engine coolant circulation independent of belt-driven mechanical systems, enabling more efficient thermal management and freeing up parasitic horsepower losses. The pump arrives as a comprehensive kit with all gaskets, hardware, and wiring harness included for straightforward installation.

The LS-1 pump features a 1-1/4 inch hose barb inlet compatible with standard cooling system plumbing, and a black anodized aluminum construction that resists corrosion while maintaining a clean appearance in the engine bay. The electric-drive design allows coolant flow to be precisely controlled and modulated based on actual cooling demand rather than engine RPM, which is particularly valuable in high-performance and custom LS builds where traditional belt-driven pumps may introduce unnecessary drag. The compact footprint and integrated wiring make this unit suitable for both stock and modified engine applications.

LS-series engine swaps and performance builds rely on efficient heat rejection to maintain stable operating temperatures under sustained load. The MEZIERE electric water pump is engineered for builders and enthusiasts who prioritize system reliability, reduced mechanical drag, and the flexibility to integrate electronic coolant management. The complete kit eliminates guesswork on assembly, providing all fasteners and sealing components needed for proper installation on LS-powered vehicles, trucks, and specialty projects.

Weighing 8.45 lbs and measuring 8.2 x 5 x 13.9 inches, this pump balances functionality with compact mounting geometry. The black anodized finish complements modern engine bay aesthetics while providing surface protection in demanding environments.
