LS Electric Water Pump Black

The LS Electric Water Pump Black by Allstar Performance is purpose-built for LS engine builders and street rod enthusiasts seeking reliable active cooling without belt-driven parasitic loss. Whether you're assembling a modern LS swap, building a dedicated track car, or upgrading an existing high-performance installation, this electric water pump eliminates the need for mechanical pulleys and serpentine belts. It's engineered for builders who demand independent temperature control and want to reclaim horsepower lost to traditional mechanical pump drag.

This pump features a black finish and is specifically designed for LS-platform engines, including LS1, LS2, LS3, and LS9 variants. The electric drive eliminates the efficiency penalty of mechanical cooling systems—typically 5–10 horsepower at the crank—while allowing precise pump speed regulation via aftermarket ECU tuning or dedicated controllers. The design ensures consistent coolant circulation regardless of engine RPM, preventing both overcooling at idle and undercooling at peak load, critical for maintaining optimal combustion chamber temperatures and ring seal integrity in high-boost or naturally aspirated applications.

Installation is ideal for LS engine swaps into classic trucks, Camaros, Corvettes, and custom chassis where weight savings and underhood packaging efficiency matter. The compact form factor simplifies header routing and alternator placement compared to belt-driven setups. Technicians performing LS conversions benefit from cleaner engine bay layouts and the ability to run remote radiators without concern for pulley alignment. Compatibility extends to most LS-based builds utilizing standard cooling system plumbing, though integrating a quality electric fan controller and relay harness is recommended for optimal system performance and long-term reliability.
