• Worth knowing The number stamped on the old part is the only reliable identifier, since two parts can look identical and differ by a millimetre or by rotation direction.

Varies by build: Colorado, side panel, with flares.

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.

Match this against the part you are taking off rather than against a photo. If the number is unreadable, send us the VIN and we will confirm it.
