FAW Accessories J6 Diesel Cooling Water Pump Assembly

The Engine Water Pump (Part No. 5038668AB) is an original equipment manufacturer (OEM) component produced by Mopar, specifically engineered for high-performance 5.7L HEMI® and 6.4L SRT HEMI® V8 engines used across Chrysler Group’s flagship vehicle lineup. As a core element of the engine cooling system, this water pump ensures continuous circulation of coolant through the engine block, cylinder heads, radiator, and heater core — effectively regulating operating temperature and preventing overheating under both normal and extreme driving conditions.

Constructed with a premium aluminum housing and a precision-cast metal impeller, this pump delivers reliable flow efficiency, long-term corrosion resistance, and quiet operation. It is driven via the engine’s serpentine belt system, making it compatible with modern accessory drive layouts. Designed to meet strict OEM durability standards, 5038668AB was widely used from 2011 to 2021 on popular models including the Chrysler 300, Dodge Challenger, Charger, Durango, and Jeep Grand Cherokee.
