Wynn's Cooling System Flush

Wynn's Cooling System Flush is a concentrate designed for cleaning cooling systems in motor vehicles. This concentrate is a powerful, acid-free radiator cleaner. It effectively removes rust, deposits, oily residues, and scale. It offers excellent performance in all types of coolant, including OAT coolant (Organic Acid Technology). It keeps dirt suspended during the cleaning process. Wynn's Cooling System Flush does not harm rubber hoses, seals, or metals in the cooling system and is particularly effective in all closed-loop cooling systems. It restores optimal cooling and the operation of the control components of the cooling system.

It is suitable for all water-cooled systems of gasoline and diesel engines and is recommended during coolant changes (following manufacturer guidelines). It is especially effective for cleaning older cooling systems.

Instructions for use: Pour the entire contents of the 325 ml can into the cooling system: over the expansion tank if part of the system circuit (2 hoses: supply and return) or directly into the radiator if there is an overflow tank with a hose. For enhanced performance, first replace the old coolant with water, then add Wynn’s Cooling System Flush. Allow the engine to warm up and set the heater to "WARM." Let the engine idle for 10 minutes. Turn off the engine and allow it to cool down, then open and drain the system. While the system is still open, flush with water until it runs clear, then close and refill with new coolant. The contents of a 325 ml can treat cooling systems up to 12 liters. If necessary, add Wynn's Cooling System Stop Leak as a preventive measure.
