Fluid type and capacity can change by engine, drivetrain, and transmission. Verify the exact branch before filling anything. Once the spec is confirmed, use the supplies and purchase links below to build the full one-trip shopping list before you start the repair.
Use the archive navigator when you need the exact engine, trim, or production-branch manual instead of a broad year-range summary. That keeps the buying list and repair steps aligned with the real vehicle.
These links are built from the same specs shown on this page so users can move from lookup to purchase faster. Confirm exact engine and trim if your vehicle has multiple variants, then build the full cart before you step away from the computer.
