Oil Pump

The Mopar Engine Oil Pump (part number 53021622AF) is a genuine OEM replacement for the original oil pump in a wide range of Mopar, Chrysler, Dodge, and Jeep vehicles equipped with the 5.7L V8 HEMI MDS engine. This oil pump replaces older part numbers 53021622AD and 53021622AE, ensuring compatibility with specified models. Key specifications include dimensions of 8.1 x 8.1 x 4.1 inches and a weight of 3.30 pounds. The product is new and comes with Mopar's factory warranty, assuring buyers of its quality and reliability. The Mopar 53021622AF is compatible with numerous vehicles from 2004 to 2008, including Chrysler 300, Chrysler Aspen, Dodge Charger, Dodge Durango, Dodge Magnum, Dodge Ram 1500, 2500, and 3500, as well as Jeep Commander and Jeep Grand Cherokee. Specific trims and configurations for each model are detailed in the fitment information, ensuring precise application. For instance, it fits the 5.7L V8 HEMI MDS engine variants across these models, often specifying drivetrain options like 2WD or 4WD, and trim levels such as Limited, R/T, or Laramie. Installation notes indicate that the oil pressure relief valve should not be removed from the oil pump housing, as doing so necessitates replacing the entire assembly. The installation process involves draining coolant, removing the timing chain cover and oil pan, detaching the pick-up tube, and then removing and installing the oil pump with its mounting bolts tightened to specified torque levels. Proper sealing with a new O-ring on the pick-up tube is essential. After installation, the vehicle should be filled with the correct type and quantity of oil, the filter changed, and the radiator refilled. The engine should then be run to check for fluid pressures and leaks. A common issue with some replacement oil pumps can involve oil pressure problems stemming from a collapsing relief valve and spring, highlighting the importance of using genuine Mopar parts.
