Detailed Description

Autotecnica GM0818589 is a body gasket and sealing system component made for the front left door on 2007-2014 Cadillac Escalade, 2007-2014 Chevrolet Tahoe, 2007-2014 GMC Yukon, 2007-2013 Cadillac Escalade EXT, and 2007-2013 Chevrolet Avalanche. The EPDM material is selected for sealing applications where flexibility, compression recovery, and resistance to everyday exposure matter. With a 157-inch length and 1.75-inch width, this door seal is built around the dimensions needed for a proper perimeter seal on the listed vehicles.

This part cross-references GM OE numbers 15258925 and 22766409 for the same application. If you are searching for a front left door seal for a 2007-2014 Chevrolet Tahoe, a 2007-2014 GMC Yukon, or a 2007-2014 Cadillac Escalade, GM0818589 is the direct replacement to review.

What It Helps Address

• Air leakage around the front left door opening
• Water intrusion at the door perimeter
• Wind noise from a worn or compressed seal
• Dust and road debris entering the cabin
• Poor door-to-body sealing caused by aging rubber

Installation Notes and Tips

Verify the vehicle year, model, and front left position before installation. Compare the existing seal length and profile to GM0818589 to confirm the correct body gasket for your application. Clean the mounting surface thoroughly so the new EPDM seal seats evenly along the door frame.
