BCBC M588 Engine Oil Pump

Engine Oil Pump Overview

This Melling engine oil pump, part number M588, is a standard replacement for a wide range of late-model Chrysler, Dodge, Jeep, and Ram applications. It is built for consistent oil pressure and efficient circulation in engines that use a timing chain drive.

Compatible with Chrysler Pacifica, Dodge Durango, Jeep Wrangler, and Ram 1500 applications, M588 is engineered for direct replacement use where the OE-style pump design is required.

Key Features

• Standard replacement engine oil pump for OE-style service
• Gear-type pump with powdered metal rotor construction
• Cast aluminum housing with cast iron cover
• Precision-ground end plates for improved wear resistance
• Timing chain drive configuration
• Gasket or seal included
• Individually tested for pressure and flow

Detailed Description

Melling M588 is designed around gear and gerotor pump technology to deliver controlled oil pressure and efficient pump operation. Close-tolerance machining helps maintain proper pressure output, while the precision-ground end plates support wear resistance under engine operating conditions. The cast aluminum housing, cast iron cover, and rust preventative finish add durability to the assembly.

This part number, M588, cross-references DNJ OP1184 and Sealed Power 224-43710 for the same application. It is a strong fitment match for Chrysler Pacifica, Jeep Grand Cherokee, and Ram ProMaster 1500 applications that require a timing chain-driven oil pump.

What It Is Used For

• Restoring proper engine oil pressure
• Replacing a worn or inefficient oil pump
• Addressing low oil pressure concerns
• Supporting consistent lubrication throughout the engine
• Correcting pressure and flow issues caused by pump wear

Installation Notes and Tips

Verify engine application, drive type, and OE design details before installation. This pump uses a timing chain drive and includes a gasket or seal, while the product data does not list bolts, a drive shaft, or a pickup screen as included. Confirm all mating surfaces are clean and inspect related lubrication components during service.

Quality Assurance

Melling manufactures this oil pump to high production standards and tests each unit for pressure and flow under conditions that simulate engine operation. The M588 is built with high-quality materials and close-tolerance machining for dependable service.
