Constructed from Billet 6061 Aluminum and made in the USA, this pump offers a flow rate of 55 gallons per minute. It features a 1 1/4” upper hose connection and has -08ORB high and low-pressure heater ports, with stainless mounting hardware and gaskets included.

Show original supplier description

The Meziere electric water pump is a high-flow cooling solution engineered for the 2010 and later Camaro L99 with an automatic transmission. Constructed from billet 6061 aluminum with a stainless steel main shaft and a high-performance ceramic seal, this pump provides a 55-gallon-per-minute flow rating to support high-horsepower engine demands. The design includes an integrated idler pulley, ensuring that all factory serpentine belt-driven accessories remain in their stock configuration. Each unit is supplied with necessary mounting hardware, gaskets, and fittings, including -08ORB ports for heater and bypass lines. It does not fit factory supercharged engines. Furthermore, this pump is not compatible with vehicles equipped with a factory manual transmission; for those applications, or if the engine has been modified by removing the factory VVT front cover, users should use the WP329N model instead.
