Additional Notes
- The Oldsmobile Firenza (USA / CAN) power steering specifications cover three engine configurations: the 1.8-liter (1982-1986), the 2.0-liter (1982-1988), and the 2.8 V6 (1985-1987).
- Across all three engine configurations, the steering pump capacity is rated at 0.5 liter, representing the fluid volume held within the pump reservoir alone rather than the full hydraulic circuit.
- The complete circuit capacity, which accounts for the total fluid volume throughout the entire power steering hydraulic system including lines and the rack or gear assembly, is 1.25 liters for all three configurations.
- The difference between the 0.5-liter pump figure and the 1.25-liter complete circuit figure means a full system overhaul or flush requires 2.5 times more fluid than a pump-only service would suggest.
- All three configurations carry a normal use condition designation, meaning the listed capacities apply under standard operating conditions rather than a severe-duty or first-change-only scenario.
- The 1.8-liter and 2.0-liter variants share an overlapping production window from 1982 onward, yet both carry identical pump and complete circuit capacities, indicating no displacement-driven difference in power steering system volume for those two engines.
- The 2.8 V6, introduced in 1985, also shares the same 0.5-liter pump and 1.25-liter complete circuit figures, meaning the larger displacement V6 configuration did not require a higher-capacity power steering system compared to the four-cylinder variants.
