Detailed Product Overview

This Dorman oil drain plug is engineered for vehicles that use an M12-1.75 coarse-thread drain opening and a conventional drain method. The steel body provides the needed durability for repeated oil service, while the rubber sealing component helps create a tight seal at the oil pan. The blue and silver finish makes the plug easy to identify during maintenance, and the standard replacement grade supports straightforward service on GM platforms such as the Chevrolet Equinox, Silverado 1500, Tahoe, and GMC Terrain.

This part number 090-948CD also cross-references GM 55577568 for the same application. Use it when replacing a stripped, leaking, or missing drain plug on vehicles including the Buick Encore GX, Chevrolet Malibu, and Cadillac XT5.

What It Helps Solve

• Oil leaks at the drain plug sealing surface
• Damaged or stripped drain plug threads
• Missing drain plug after service
• Improper sealing from worn plug hardware
• Service issues on GM oil pans with M12-1.75 threads

Installation Notes and Tips

Verify thread size, pitch, and head tool access before installation. Clean the oil pan threads and sealing surface thoroughly, then install the plug with the correct tool engagement to avoid cross-threading. This drain plug uses a gasket seal and does not require a special tool for service. Confirm vehicle-specific fitment for models such as the Chevrolet Trailblazer, GMC Yukon, and Cadillac Escalade before ordering.
