F Panel – GM (85775360)

Factory part number 85775360: a f panel supplied by GM. It is catalogued under Covers & Caps > Panels & Plates.

• 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.
• Plastic covers harden with heat cycles, so a cover that has been on the vehicle for a decade often cracks at the screw bosses when refitted.

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. The photographs on a listing show the actual stock item, so compare the mounting points and the connector or fitting rather than the overall shape.

Confirm the number before you order, because a near match will bolt on and still be wrong. Send the VIN if the old marking has gone. Leaves our US warehouse in one to two business days, and shipping is free over $59.
