F Panel – GM (84745986)

The f panel here is the GM part, numbered 84745986. It is catalogued under Covers & Caps > Panels & Plates.

• A cap that vents and a cap that does not are visually similar, and swapping them gives a fault code or a pressure leak rather than a fit problem.
• Inspection covers are usually the first thing removed and the last thing reordered, which is why a missing cover often shows up as a rattle rather than a leak.
• Where a cover sits against a painted panel, a slight shade difference is normal on service parts supplied primed rather than finished.

Covers that seal a fluid opening normally carry a single-use gasket or O-ring, and reusing the old one is the usual reason a leak comes back. On panel and plate parts, check whether the original is held by clips, screws or both. The fasteners are often sold separately and are often what actually broke.

The part number is the thing to verify. Where the old part carries no legible number, a VIN and a photograph are enough for us to identify it. Ships from our US warehouse in one to two business days, free over $59.
