Dorman Engine Oil Drain Plug for Ram and Dodge

Dorman 090-173 is a direct replacement engine oil drain plug for vehicles using an M18-1.5 fine thread. It is built from steel with a silver finish and includes a gasket or seal to help restore a proper oil pan seal after service.

For Ram 2500, Ram 3500, Ram 4000, and Dodge Ram 2500/Ram 3500 applications, this drain plug matches the original thread pitch and uses a square head drive for service with a 6-point socket. The Dorman 090-173 is a practical OE-style replacement when the original plug is damaged, worn, or no longer sealing correctly.

Key Features

  • Direct replacement engine oil drain plug for M18-1.5 applications
  • Steel construction with silver finish
  • Fine thread design with 18 mm thread diameter
  • Includes gasket or seal for sealing at the oil pan
  • Square head drive with 31.25 mm head size and 6 socket points
  • Conventional drain method for standard oil service
  • Fits Ram and Dodge Ram diesel and gas applications listed below

Detailed Description

This Dorman oil drain plug is engineered to match the original equipment thread pitch and sealing style, helping maintain a secure closure at the engine oil pan. The pilot point molded gasket design and included gasket type support a proper seal during routine oil changes. With metric M18-1.5 threads, steel construction, and a conventional drain design, part number 090-173 is suited for service on Ram 2500 and Ram 3500 trucks across multiple model years, as well as Ram 4000 and select Dodge Ram 2500/Ram 3500 applications. This part cross-references 1053 and 5080631AA for the same application.

What It Helps Fix

  • Oil leaks caused by a worn drain plug seal
  • Stripped or damaged drain plug threads
  • Improper sealing after repeated oil changes
  • Difficulty servicing an oil pan with the wrong thread pitch
  • Replacement needs after a missing or corroded drain plug

Installation Notes and Tips

Verify the oil pan thread size before installation. This plug uses M18-1.5 metric fine threads and a square head drive; a 6-point socket sized for the head can help during removal and tightening. Clean the drain opening and sealing surface before installing the new plug and gasket. Confirm the drain plug seats fully without cross-threading.

Quality Assurance

Dorman manufactures this replacement drain plug as a direct-fit service part for the listed Ram and Dodge Ram applications. The design follows the original thread pitch and sealing requirements to support a proper oil pan seal during maintenance.
