The OEM Mopar 68370830AA Auxiliary Coolant Pump is a genuine factory replacement component designed for compatible 6.2L Supercharged Gen 3 HEMI applications, helping maintain proper coolant circulation through the vehicle’s auxiliary cooling system. Mopar engineered this pump as a direct replacement for the original equipment unit, making it an ideal solution when servicing a worn, damaged, or malfunctioning factory auxiliary pump. The 68370830AA is specifically associated with 6.2L Supercharged HEMI and 6.2L Supercharged High Output engine configurations, making it relevant to high-performance Hellcat-family vehicles where effective cooling is an important part of maintaining consistent operation. Genuine Mopar construction provides factory-style fitment and integration with the original cooling system without relying on a universal pump or custom adaptation. For Gen 3 HEMI owners maintaining a factory-based supercharged cooling system, this OEM auxiliary coolant pump provides a straightforward replacement option with the correct application-specific design.

The auxiliary cooling circuit plays an important role in supercharged Gen 3 HEMI applications. As the supercharger compresses incoming air, heat is generated, and managing that heat is critical to maintaining consistent intake-air temperatures. The cooling system relies on proper coolant circulation, making a healthy auxiliary pump an important component in the overall system.

A weak or failed coolant pump can reduce circulation and compromise the cooling system’s ability to move heat away from critical components. For street-driven Hellcats, high-horsepower builds, and vehicles that regularly see drag strip or other demanding performance use, maintaining the cooling system is especially important. Replacing a failing pump with the correct OEM component restores the system with hardware designed around the vehicle’s original configuration.

Mopar part number 68370830AA is identified as an Auxiliary Coolant Pump, and it is also referenced as an auxiliary pump, cooler pump, or water pump depending on the parts catalog. The component is sold as a new, direct-replacement Mopar part rather than a universal electric coolant pump. Published specifications list dimensions of approximately 9.4 x 9.5 x 9.8 inches and an item weight of approximately 9.1 pounds.

Fitment data primarily identifies the pump with 2018-2023 Dodge Challenger and Charger applications, including 6.2L Supercharged HEMI performance models. Catalog listings include Challenger SRT Hellcat, Demon, Redeye, Super Stock, and related configurations, along with Charger Hellcat and Redeye applications depending on model year. Because Mopar catalog fitment can vary based on VIN, engine configuration, and vehicle options, exact compatibility should be verified before ordering.

For modified Gen 3 HEMI vehicles, replacing the auxiliary pump should also be considered as part of the complete cooling-system strategy. Larger heat exchangers, intercooler upgrades, supercharger modifications, pulley changes, and increased boost can all place additional emphasis on charge-air temperature management. While this OEM pump is a replacement component rather than an aftermarket high-flow upgrade, it provides the factory pump configuration needed for compatible cooling systems.

Whether you’re repairing a failed pump, refreshing an aging cooling system, or completing a 6.2L Supercharged HEMI build, the Mopar 68370830AA Auxiliary Coolant Pump delivers OEM fitment and function for compatible applications.
