Why the USA-specific catalog matters

Vehicles delivered to the USA can differ from other regions in engines, emissions standards, diagnostic calibrations, lighting and safety equipment, as well as trim packages. This catalog is filtered for the USA, helping you navigate variations such as federal/California emissions equipment, FMVSS lighting, towing or cooling packages, and model-year running changes specific to the U.S. market. Using the correct region ensures the diagrams and OEM numbers you see match the vehicle built for American roads, fuel and climate conditions—from hot summers and cold winters to long interstate trips and dense city traffic.

How to use the catalog

1. Confirm you are on the USA page; this catalog is already filtered for the USA region.
2. From the model list above, choose the needed series (for example, Encore, Envision, Enclave, Regal, LaCrosse).
3. Select the correct generation and production years that match the vehicle, e.g. Enclave 2nd Generation (2018 - 2024) or Century 9th Generation (1997 - 2005).
4. Open the required assembly group: engine, transmission, suspension, brakes, body, interior or electrical systems.
5. Use the diagram to identify the exact component and read its OEM part number(s) in the parts list.
6. Use the OEM number to order original parts, verify supersessions or check compatibility with related components.
7. If the vehicle’s configuration is uncertain, refine the search with a VIN-based lookup to load diagrams and parts data for the exact build.

VIN and part number search

For the most precise selection, decode the vehicle identification number to reveal your BUICK's exact configuration — series, engine, transmission, and USA-specific equipment like EPA/CARB emissions, SAE lighting, DOT safety equipment, and Federal/California-spec components. Use the VIN decoder for BUICK to open a catalog filtered to your build. If you maintain multiple brands or need to identify a vehicle with unclear history, the cross-brand VIN decoder helps with any car or truck. You can also search directly by OEM part number to verify applicability across engines, trims, and model years in USA.
