Detailed Description

Melling M297 is engineered and assembled to production standards using quality materials and close-tolerance machining. The machined gears, precision-ground end plates, and rotary design help maintain proper engine pressure and efficient oil delivery. This oil pump is a direct-fit style replacement for stock engine builds in Jeep Liberty, Dodge Dakota, Dodge Nitro, Ram 1500, and related applications listed in the fitment data. The M297 part number also cross-references DNJ OP1100 for the same application.

Stock product line oil pumps are built for straightforward replacement use, with a focus on consistent pressure, flow, and material quality rather than modified performance output. For buyers servicing a Jeep Grand Cherokee, Dodge Durango, or Chrysler Aspen, M297 provides a standard-volume, standard-pressure solution that matches original-style operation.

Common Problems This Part Can Address

• Low oil pressure caused by a worn pump
• Inconsistent oil delivery from aging internal components
• Excessive wear in the pump gears or end plates
• Oil circulation issues in a high-mileage engine
• Replacement needs during engine service or rebuild work
