BCBC M452HV Engine Oil Pump

Engine Oil Pump Overview

The Melling M452HV is a high volume engine oil pump built for applications that need increased oil flow and stable pressure control. It is made in the USA and uses rotary pump construction with gear and gerotor technology for consistent operation.

Compatible with a wide range of Chrysler, Dodge, Jeep, and Ram applications, this pump is a fitment-based replacement for engines that call for a high volume oiling solution. The M452HV is engineered for dependable pressure at idle and efficient oil delivery under operating conditions.

Key Features

• High volume design increases oil flow by an average of 12% over stock.
• Standard pressure pump with improved design grade.
• Aluminum housing with cast iron cover for durable construction.
• Steel rotor and precision-ground end plates for wear resistance.
• Gasket and O-ring included for service-ready assembly.
• Adjustable pickup screen and crankshaft drive type.

Detailed Description

The Melling M452HV oil pump is designed around high volume performance, using close-tolerance machining to support proper engine pressure and efficient pump operation. Its rotary design, steel rotor, and precision-ground end plates reflect the brand’s focus on controlled oil delivery and long-term wear resistance. This part cross-references Mopar 68195993AD and 68195993AB for the same application.

Fitment includes 2009-2026 Dodge Durango, 2009-2023 Dodge Challenger, 2009-2023 Dodge Charger, 2009-2021 Jeep Grand Cherokee, and 2011-2024 Ram 1500, along with additional Chrysler, Jeep, and Ram applications. Use the M452HV when the engine specification calls for a high volume oil pump with standard pressure characteristics.

What It Is Used For

• Restoring oil pressure at idle when the original pump is worn.
• Improving oil flow in engines that require a high volume pump.
• Addressing pressure loss caused by internal pump wear.
• Replacing a pump with damaged gears, rotor, or cover surfaces.
• Supporting consistent lubrication in demanding engine operation.

Installation Notes and Tips

Verify engine application, pump type, and pickup tube dimensions before installation. Confirm that the crankshaft drive arrangement and mounting hole pattern match the engine specification. Inspect the oiling system, pickup screen, and sealing surfaces during service to help ensure proper pump operation.

Quality Assurance

Melling manufactures this pump in the USA and tests each unit for pressure and flow under conditions that simulate engine operating conditions. The M452HV is built to production standards using high-quality materials and close-tolerance machining.
