Purpose and Specifications

SWAG 64 92 4704 is a mineral-based central hydraulic fluid designed for hydropneumatic suspension systems, level control, and steering mechanisms in European vehicles. This green-colored fluid operates reliably across a wide temperature range from -40°C to +100°C, making it suitable for both cold climates and high-heat driving conditions.

The fluid meets strict international standards including DIN 51524 Teil 3, ISO 7308, LHM Plus, and PSA B71 2710, ensuring compatibility with Citroën, Peugeot, and other European manufacturers. Its mineral composition provides excellent cold-flow properties, allowing your suspension and steering to respond instantly even in freezing temperatures, while maintaining protective film strength at engine operating heat.

Key protective benefits:

• Prevents corrosion and cavitation damage to hydraulic pumps and valves
• Stops foam formation and sedimentation that can clog fine passages
• Protects hoses and seals from degradation
• Delivers consistent performance without viscosity breakdown under pressure

When to Use / Replace?

Replace your hydraulic fluid every 2-3 years or 40,000-60,000 km, whichever comes first. If your vehicle experiences harsh driving, frequent towing, or operates in extreme cold, check fluid condition annually. Signs of needed replacement include darkened color, visible sediment, reduced suspension responsiveness, or steering stiffness.

This 1-liter bottle is ideal for top-ups and small system refills. For complete system flushes, calculate your vehicle's total hydraulic capacity and purchase accordingly.

Frequently Asked Questions

Q: Can I mix this with other hydraulic fluids?
A: SWAG 64 92 4704 is formulated to work with silicate-free antifreezes and is compatible with systems using LHM Plus specifications. Do not mix with mineral oils from different manufacturers without consulting your vehicle manual, as additive packages may conflict.

Q: Why does my suspension feel softer in winter?
A: This fluid's cold-flow design prevents thickening at low temperatures, but mineral hydraulics naturally become slightly less responsive in extreme cold. This is normal and reverses as the engine warms. If stiffness persists after 10 minutes of driving, have your system inspected for leaks.

Q: Is this safe to handle?
A: Mineral hydraulic fluid is harmful if swallowed or inhaled in mist form. Avoid skin contact and use in well-ventilated areas. Wash hands thoroughly after handling. Keep away from children and pets.
