Land Rover Cold Climate Power Steering & ACE Fluid (1 Litre)
Ensure smooth, responsive steering and reliable hydraulic pressure with this specialist 1-litre cold climate power-assisted steering and Active Cornering Enhancement (ACE) fluid. Engineered to meet strict Land Rover specifications (STC50519 / LRN2261), this fully synthetic central hydraulic fluid (CHF) is specifically formulated to withstand extreme temperature fluctuations—maintaining peak viscosity and performance from deep sub-zero winters up to high operating heat.
Whether you choose the high-grade aftermarket alternative (STC50519) or the official factory-branded Genuine Land Rover option (STC50519LR), both formulations protect sensitive pumps, valves, and steering components against premature wear, cavitation, and heavy feedback.
Key Features:
- Dual-System Compatibility: Specially formulated for use in both power-assisted steering systems and Active Cornering Enhancement (ACE) units on compatible Land Rover vehicles.
- Cold Climate Performance: Exceptional low-temperature fluidity prevents heavy steering and pump strain during freezing morning starts. It is designed for use from -40°C to +100°C
- High Thermal Stability: Resists thinning or breaking down under continuous high-load driving conditions and demanding off-road manoeuvres.
- Comprehensive Component Protection: Actively safeguards internal seals, hoses, and metal valves against corrosion, friction wear, and foaming.
- Precise Hydraulic Pressure: Ensures consistent flow characteristics required for modern hydraulic steering networks, eliminating noise and "notchiness."
- Convenient 1-Litre Bottle: Ideal size for fluid top-ups or complete hydraulic system flushes.
