Power Steering Fluid (H3)
Power steering fluids are primarily categorized into three types based on composition: mineral (conventional), synthetic, and Automatic Transmission Fluid (ATF)-based.
Types: (H4)
- Mineral (Conventional): Older vehicle models that specifically recommend mineral-based fluids.
- Synthetic: Modern, high-performance, or specialized vehicles, often specified by European manufacturers (e.g., VW, BMW, Volvo).
- ATF-based: Many contemporary vehicles, particularly those from GM, Ford, Honda, and Toyota, where the manufacturer specifies ATF (e.g., Dexron, Mercon).
Key Features: (H4)
- Hydraulic assistance: Transmits power and pressure to reduce the effort required to turn the steering wheel.
- Lubrication: Reduces friction between moving parts, protecting the pump, gears, and seals from wear and tear.
- Heat dissipation: Carries heat away from the system components to prevent overheating.
- Corrosion prevention: Contains inhibitors to protect metal components from rust and corrosion.
- Foaming resistance: Includes anti-foaming agents to ensure consistent performance and prevent air pockets in the hydraulic system
- Seal compatibility: Formulated to be compatible with the specific rubber and plastic seals in the power steering system to prevent leaks.
