Show original supplier description
The Meziere WP319 electric water pump serves as a high-performance cooling solution for 1999-2009 GM LS-powered cars, including Corvette and Camaro models. This unit flows 55 GPM and is constructed with a durable CNC-machined aluminum housing, heavy-duty motor windings, and a carbon-ceramic seal. It features a unique design that relocates the thermostat from the lower inlet to the upper outlet. Installation requires specific attention to factory components. You must remove the factory thermostat before installing this pump, which comes with a 185-degree thermostat pre-installed. The unit accepts factory-style thermostat housings and includes the necessary gaskets and hardware. This pump is specifically not compatible with truck accessory spacing and belt routing, nor is it suitable for factory supercharged engines such as the LS9 or LSA. It is intended for use with 1999-2009 LS engines; for 2010 and later models, different Meziere part numbers are required. For optimal operation, users may need to incorporate additional items like a relay kit or a specific water neck, depending on their existing configuration.
