Meziere WP118 Electric Water Pump for GM LT1/LT4 Engines

The Meziere WP118 is a high-performance electric water pump designed as a direct replacement insert for GM LT1 and LT4 engines from the 1990s. This American-made pump eliminates the horsepower loss associated with traditional mechanical water pumps while providing reliable cooling for street and drag strip applications.

Key Features:

• CNC-machined from 6061-T6 billet aluminum with black anodized finish
• Delivers 43 gallons per minute free flow rating for engines up to 650 horsepower
• Lightweight design weighs only 3.5 pounds, reducing overall engine weight
• Stainless steel large diameter main shaft with high-performance ceramic seal
• Epoxy-coated motor windings with RF suppression circuit
• Draws only 6-7 amps under normal operation
• 2,400+ hour life expectancy for reliable long-term performance
• Measures 3.0 inches from mounting surface to pump tip

Installation is straightforward as the pump functions as an insert into the factory pump housing, reusing original hardware. The electric design eliminates the need for the heavy factory timing chain and provides over 10 rear-wheel horsepower gains. The relocated seal drain prevents pump leaks from causing Optispark failure. Backed by Meziere's 2-year unlimited mileage warranty.
