Core Functions

• Fluid Circulation: The primary function is to guide the return flow of hydraulic fluid, completing the power steering system’s fluid circulation cycle.
• Pressure Resistance: Withstands the hydraulic pressure of the return line, preventing hose burst or deformation under working conditions.
• Leak-Proof Protection: Tight fittings and high-quality rubber material ensure no fluid leakage, maintaining stable hydraulic pressure in the system.

Notes: This Power Steering Pressure Return Hose Line is model-specific and designed exclusively for the listed Mercedes W164 series GL models. Do not use it for other models or variants to avoid mismatched fittings, insufficient pressure resistance, or fluid leakage. During installation, ensure the hose is routed correctly (avoiding kinks or contact with high-temperature components) and fittings are tightened securely. Use only Mercedes-approved power steering fluid. Periodically check for hose aging, cracks, or leakage, and replace immediately if faulty to maintain the power steering system’s normal operation and driving safety.
