Tec4 Cooling System Cleaner is a professional-grade chemical flush engineered to dissolve and remove rust, scale, limescale deposits, and inorganic sludge from vehicle cooling circuits. Over time, neglected coolant degrades and forms hard insulating deposits across internal engine jackets and radiator cores, leading to localized hot spots and engine overheating.

Formulated with fast-acting chelating agents and scale-dissolving detergents, Tec4 Cooling System Cleaner thoroughly restores maximum coolant circulation and heat transfer efficiency without harming delicate cooling system metals, gaskets, or rubber hoses.

Key Performance Benefits

• Dissolves Rust & Scale: Rapidly breaks down mineral scale, rust scale, and oxide buildup that restrict coolant flow and cause engine overheating.
• Restores Maximum Heat Transfer: Strips away insulating scale layers from cylinder walls and radiator channels to recover peak cooling performance.
• Prevents Overheating Hot Spots: Eliminates localized thermal stress points across cylinder heads to protect against head gasket failure and warping.
• Unblocks Cabin Heater Cores: Clears mineral blockages in restricted heater matrix tubes to restore full interior heating capability.
• Safe for System Components: Formulated without harsh mineral acids, ensuring complete safety for aluminium alloys, solder, plastics, and seals.
• Prepares System for Fresh Coolant: Thoroughly neutralizes and cleans internal surfaces to ensure new antifreeze/coolant achieves maximum service life.
