METHOD OF USE:
> Shake the bottle well and pour its contents into the cooling system through the expansion tank separating the system circuit (2 hoses: outlet and return), or directly into the radiator if an expansion tank with one hose is installed.
> For best results, first replace the old coolant with water and then add WYNN'S Radiator Flush.
> Warm up the engine by setting the heating system control to the "HOT" position.
> Let the engine idle for about 10 minutes. The heater should be in the "HOT" position.
> Switch off the engine and allow it to cool.
> Open the drain valve and empty the system.
> Without closing the drain valve, flush the system with water until it is clean.
> Then close the drain valve and fill the system with coolant.
> One 325ml bottle is enough for a 5 - 12 liter cooling system.
> For additional protection against leaks, WYNN'S Radiator Stop Leak can be added. Surfactants (PAM): < 5% (non-ionic PAM), NTA (nitrilotriacetic acid) and their salts.
