ZOLLEX Radiator flush provides an excellent cooling system flush within 10 minutes, removing rust and scale. It does not damage the rubber seals, metal parts and gaskets during use.
Application: All operations must be carried out on a cold engine. Remove the radiator cap, drain the coolant (equal volume to the additive volume). Start the engine and increase the temperature of fluid up to operating temperature. Shake the bottle and pour the additive into the radiator. Slightly tighten the radiator cap, leaving some room for the steam. Let the engine idle for 15 minutes then turn off engine, cool the radiator and drain the coolant. Flush the radiator with clean water and then fill the radiator with new coolant.
