K2 KULER Radiator Fluid Concentrate 5L (T215C) — red coolant concentrate

K2 KULER Radiator Fluid Concentrate 5L (red coolant concentrate) is a concentrated engine coolant supplied in a 5-litre container intended for dilution before use. Designed to be mixed with water according to vehicle manufacturer recommendations, this red coolant concentrate helps maintain optimal engine temperature, protect cooling system metals from corrosion, and provide freeze protection when prepared at the correct concentration. The product is suitable for passenger cars and light vehicles that require a red-coloured antifreeze/coolant formulation.

Advantages

The concentrate format allows flexible dilution ratios to match regional climate and vehicle specifications while reducing packaging waste compared with ready-to-use products. When correctly mixed, the coolant provides corrosion protection for aluminium and other common engine metals, reliable heat transfer to stabilize engine temperature, and freeze and boil-over protection appropriate to the selected mixture. The red colouring helps with correct fluid identification during service and maintenance.

Suitable for

• Passenger cars and light commercial vehicles requiring a red coolant formulation
• Cooling systems needing long-term corrosion protection for aluminium and steel components
• Vehicles operating in climates where freeze protection and controlled boil-over limits are necessary
• Workshops and home users who prefer to store concentrated antifreeze for on-demand mixing

Key specifications

• Form: liquid concentrate supplied in a 5-litre container
• Colour: red for easy identification
• Intended use: engine antifreeze/coolant after dilution
• Compatibility: suitable for passenger cars and light vehicles that accept ethylene- or propylene-based coolant formulations (confirm vehicle requirements before use)
• Function: corrosion inhibition, freeze protection, and heat transfer

How to use

Before use, consult the vehicle manufacturer handbook to determine the required coolant type and recommended dilution ratio. Prepare the mixture by combining the concentrate with the appropriate quantity of clean water (typically distilled or demineralized water is preferred) to achieve the specified freeze and boil protection levels. Fill the cooling system with the prepared coolant while the engine is cool, follow proper bleeding procedures to remove trapped air, and check for leaks. Dispose of any unused mixed fluid or rinse water according to local environmental regulations.

Usage recommendations

Always verify compatibility with your vehicle’s cooling system and follow the manufacturer’s dilution and maintenance intervals. Use distilled or demineralized water for mixing to minimise mineral deposits. Store the concentrate in a cool, dry place away from direct sunlight and out of reach of children and pets.
