Land Rover ACE & Cold Climate Fluid STC50519
Premium Quality Aftermarket Replacement Fluid
This high-performance semi-synthetic hydraulic fluid is specifically engineered for Land Rover vehicles equipped with Active Cornering Enhancement (ACE) and Power Assisted Steering (PAS) systems. Formulated to meet the stringent STC50519 specification, it provides exceptional low-temperature fluidity, ensuring smooth and responsive steering even in freezing conditions where standard mineral oils may struggle.
PERFORMANCE: Specifically designed to minimize steering pump "squeal" and protect sensitive hydraulic components from wear and corrosion.
✔ Extreme Cold Protection: Maintains viscosity down to -51°C.
✔ System Longevity: Protects seals, hoses, and valves.
✔ High Oxidation Stability: Extended service life for PAS systems.

Questions & Answers
Is this a genuine Land Rover part?
This is a premium quality aftermarket replacement fluid, formulated by 4Boats to meet or exceed the STC50519 performance standard for fitment in JLR hydraulic systems.
Can I use standard Red ATF instead of this?
We strongly advise against it. Using standard ATF in systems requiring STC50519 can lead to steering pump noise, sluggish response in cold weather, and potential long-term damage to the Active Cornering Enhancement (ACE) system.
What is the color of this fluid?
This fluid is Green in color, which is the industry standard for identifying Cold Climate PAS and ACE fluids to prevent cross-contamination with other hydraulic fluids.
