# Fluids & capacities

Select your car above to filter these cited factory specifications. Open a spec for its full source and applicability details.

Initial coverage is limited to the reviewed 1990, 1994 and 1999 manuals. Other years, coolant mixture/type, A/C refrigerant and compressor oil still need review. Missing entries are gaps in this database.

Dry-engine, oil-pan and filter capacities are separate from an oil change. An automatic transmission’s published capacity is not a drain-and-fill amount unless the manual says so. Follow the manual’s level-check procedure. Converted values are marked ≈; US and Imperial quarts are different.
