Electric Water Pump Mopar Gen-III Hemi

The Electric Water Pump for Mopar Gen-III Hemi engines delivers 34 GPM of consistent coolant flow using electric-driven circulation rather than belt-driven mechanical operation. This aluminum block-mount pump eliminates parasitic drag from traditional serpentine systems, allowing the engine to redirect power toward acceleration and efficiency. The black anodized finish provides corrosion resistance in high-temperature underhood environments where moisture and thermal cycling degrade standard finishes.

Flow capacity of 34 GPM matches the cooling demands of Gen-III Hemi platforms at cruise and full-load operation. The dual 20 AN female O-ring inlet and outlet ports accept standard -20 hose fittings, providing a secure sealed connection that eliminates weeping and blow-off risks common in older clamp-style systems. The included 1-1/2 inch fitting adapts the pump to existing block passages without requiring port modifications. Electric operation allows precise thermostat control and enables independent coolant management for turbo, supercharger, or dual-loop cooling setups—configurations that demand on-demand flow regulation rather than constant mechanical circulation.

This pump suits Mopar Gen-III Hemi owners pursuing fuel efficiency gains, hot-rod builds where serpentine-driven accessories create space constraints, or cooling-intensive applications including forced-induction and extended track use. High-performance builders favor electric water pump conversions because they isolate cooling circuits from engine load variations, stabilize coolant temperature during sustained acceleration, and free up horsepower previously absorbed by belt-driven pump parasitic load. The aluminum construction keeps weight minimal while the black anodized surface resists scale buildup from coolant additives.
