Product Benefit
Hi-Tec Radiator Flush Concentrate is a professional-grade cooling system cleaner designed to restore and maintain radiator efficiency across a wide range of vehicles and machinery. This powerful, colourless formula is engineered to remove grease, sludge, rust, and scale from radiators and the entire cooling circuit—helping prevent overheating, corrosion, and system failure.
Formulated with advanced cleaning agents, Hi-Tec Radiator Flush Concentrate is highly effective yet safe on aluminium components, rubber hoses, and gaskets when used as directed. Its high pH level (>11) and strong surfactant action deliver a deep cleanse that loosens stubborn contaminants from metal and internal surfaces. The result: a cleaner, more efficient cooling system that supports optimal engine performance.
Easy to use and fast-acting, this flush is suitable for automotive, heavy-duty, agricultural, and industrial cooling systems. For best results, the radiator should be drained, flushed with fresh water, and filled with the Radiator Flush Concentrate. Run the engine for 15–20 minutes or until hot, then carefully drain the system and flush thoroughly with water. It is critical to rinse out the product completely after use, as it is classified as a Class 8 corrosive substance and should not remain in the system.
Hi-Tec Radiator Flush Concentrate is to be used neat — no dilution required. Available in bulk, 200L, and 20L packaging, it’s an ideal solution for workshops, fleets, and industrial applications needing a reliable radiator cleaning solution before coolant replacement.
For guidance on coolant selection post-flush, consult your vehicle manufacturer or contact Hi-Tec Oils’ technical team.
