Wynns Cooling System Flush — 325ml

Part Number: WYN45944N

Wynns Cooling System Flush is a professional-grade cleaner designed to remove rust, scale, and mineral deposits from automotive cooling systems. This effective 325ml formula contains detergents and chelating agents that dissolve and suspend contaminants which accumulate over time, restricting coolant flow and reducing cooling efficiency. Regular use helps maintain proper engine operating temperature, prevents overheating, and extends the service life of key cooling system components such as the radiator, water pump, and heater core.
