CASTROL | RADICOOL PREMIX GREEN ANTIFREEZE & COOLANT 50/50 READY TO USE - Capacity 4L

CASTROL RADICOOL PREMIX GREEN ANTIFREEZE & COOLANT 50/50 READY TO USE  is an elite-grade, technologically advanced professional engine cooling fluid engineered by Castrol to deliver total thermal regulation, maximize cooling system efficiency, and provide heavy-duty mechanical defense against radiator failure and corrosion. The product is packaged in a premium golden plastic 4-liter container built with a rigid structural profile and an integrated robust top handle tailored for excellent workshop handling and precise, non-spill pouring control, paired with a secure red screw cap to preserve chemical purity. The front face features a clean, highly descriptive white commercial label with green accents showcasing the historic official CASTROL corporate emblem, followed by the Radicool signature designation, Premix formulation tag, and a technical schematic of a mechanical scroll symbolizing fluent heat dissipation. Formulated at a precise 50/50 dilution ratio using demineralized water, this technical fluid optimizes heat transfer with 100% original efficiency, preventing structural rust formation and system fouling under intense operational parameters.

Specifications:

• Brand: CASTROL.

• Product Line: Radicool Radiator Protection and Performance Series.

• Product Name: Castrol Radicool Premix 50/50 4L.

• Fluid Color Spectrum: High-visibility fluorescent green.

• Classification: Ready-to-Use (Premix) 50/50 Diluted Antifreeze & Coolant.

• Net Capacity: 4 Liters.

• Container Architecture: Heavy-duty gold-colored plastic canister with an ergonomic built-in top carry handle.

• Target Metallurgy Profile: Formulated for use in both petrol and diesel engines with aluminium components and cooling loops.

• Ready-to-Use Status: Pre-diluted configuration, do not introduce any additional water during system top-offs.

• Country of Origin: KSA.

Benefits:

• Maximized Cooling Loop Efficiency: Accelerates internal heat exchange and fluid flow through the cylinder head channels, increasing overall cooling system output and reducing load on the water pump.

• High-Stress Corrosion Barrier: Acts as a powerful mechanical barrier that blocks cavitation wear, rust, and mineral scaling across internal aluminum blocks and steel radiator cores.

• Extreme High-Temperature Defense: Prevents engine boil-overs and cooling loop bursting during severe hot-weather driving conditions or intense high-load touring.

• Calibrated No-Mix Fluidity: Pre-diluted with deionized water to prevent hard water mineral scaling and channel blockage within narrow thermostat passages.

• Mechanical Component Conservation: Actively preserves the structural elasticity of radiator hoses, internal seals, and water pump gaskets, suppressing long-term fluid leaking.

How to Use:

1. Securely park the vehicle on a flat level surface, shut off the ignition, and allow the engine block to cool down completely before checking the cooling setup.

2. Fully drain the worn, degraded coolant from the radiator bottom drain plug, flushing the internal core out if rust or contaminants are present.

3. Open the 4L golden CASTROL container and pour the ready-to-use green fluid directly into the radiator filler neck slowly without adding any extra water.

4. Top off the coolant expansion overflow reservoir tank up to the designated factory maximum cold fill indicator marker line.

5. Run the engine with the radiator cap off for a few minutes to burp out trapped air pockets, then securely retighten the cap to engage the official certified thermal boundaries.

Suitable For:

• Automotive cooling loops, high-performance gasoline and diesel engines passenger cars, light trucks, and heavy transport vehicles with aluminum radiator architectures requiring a genuine ready-to-use green 50/50 pre-diluted fluid for extended system protection.

Note:

• This trade-grade professional cooling matrix is a highly potent system stabilizer built to rigorous original technical specifications; to safeguard your vehicle's delicate internal hardware against performance-robbing thermal spikes, rust, and scale, it is highly recommended to integrate this premium engineered fluid into your standard vehicle maintenance plan.
