Original Buick parts and diagrams tailored to Canada

This page is the official-style Buick original spare parts catalog for the Canadian market. The complete list of series and generations shown above reflects vehicles supplied to Canada, from late 1970s classics through current 2025 models. Here you can browse factory parts diagrams, identify assemblies and subassemblies, read OEM part numbers, and select components by model, generation and production year. The catalog also supports VIN-based selection for precise configuration matching.

Because it is focused on Canada, this catalog considers regional specifics that affect parts selection: lighting requirements (such as daytime running lights), emissions and safety equipment, drivetrain options popular for winter, block-heater provisions, and corrosion-protection details for snowbelt conditions. Using the Canada catalog helps avoid mismatches that can occur when referencing parts lists for other regions.

Model coverage highlights

The list above includes 24 series and 58 generations relevant to Canada. A few examples to guide you:

Each generation page opens detailed diagrams for engine, transmission, suspension, steering, brakes, body, interior, electrical and heating systems, helping you pinpoint the correct OEM number and any supersessions or notes tied to a specific configuration.

How to use the catalog

1. Confirm you are on the Buick catalog for Canada. This page is already filtered to the Canadian market.
2. From the list of series above, choose your vehicle line (for example Enclave, Encore, Envision, Regal, LaCrosse, Verano, Century, LeSabre, Riviera, or others).
3. Select the exact generation and production years that match your vehicle, such as Envision 2nd Generation Facelift (2024 - 2025) or Century 9th Generation (1997 - 2005).
4. Open the relevant group of assemblies (engine, transmission, driveline, suspension, brakes, body, interior, electrical, heating/AC, etc.).
5. Use the exploded diagram to locate the needed component, then read its OEM part number in the parts list. Check notes regarding left/right side, drivetrain (FWD/AWD), engine variant, calibration or trim.
6. Copy the OEM number to order the original part or to verify compatibility and replacements.
7. If your vehicle has many options or you are unsure of the trim, use VIN-based search to filter the catalog to the exact Canadian configuration.

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 CANADA-specific equipment like Transport Canada standards, bilingual documentation, winter-rated components, and North American specifications. Use the BUICK VIN search to open a catalog filtered to your build. If you maintain multiple brands or need to identify a vehicle with unclear history, the VIN check for any brand 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 CANADA.

Why the Canada catalog matters

• Regional equipment differences: Canadian daytime running lights, lighting variants, bilingual labeling and some market-specific safety items can change part numbers.
• Climate and road conditions: cold starts, road salt, and mixed urban–highway use influence components like shields, fasteners, sensors and corrosion-prone pieces.
• Powertrain and emission calibrations: identical-looking models can carry distinct engine management, emission hardware or evaporative systems for Canada.
• Popular AWD and cold-weather options: hubs, wheel bearings, AWD couplers, heaters and related wiring may differ by trim and market.

Popular choices for Canadian drivers
