Frequently Asked Questions
- How much coolant does a Oldsmobile Silhouette hold?
- The Oldsmobile Silhouette cooling system holds 6-10 quarts total depending on the engine. A drain-and-fill replaces about 50-60% of the coolant. For a complete flush, you'll need the full capacity amount.
- What type of transmission fluid does a Oldsmobile Silhouette use?
- The Oldsmobile Silhouette transmission fluid type depends on whether it's an automatic or manual transmission and the model year. Automatic transmissions typically use ATF WS, Dexron VI, or manufacturer-specific fluid. Manual transmissions use 75W-90 gear oil.
- Does a Oldsmobile Silhouette have power steering fluid?
- 2015+ Oldsmobile Silhouette models with electric power steering don't use power steering fluid. Older models with hydraulic power steering use ATF or manufacturer-specific fluid — check your owner's manual.
- What brake fluid does a Oldsmobile Silhouette use?
- Most Oldsmobile Silhouette models use DOT 3 or DOT 4 brake fluid. DOT 4 has a higher boiling point and is preferred for performance driving. Never use DOT 5 (silicone-based) in a system designed for DOT 3/4.
