This product will not reverse pre-existing corrosion problems, and should not be used in conflict with engine manufacturer’s recommendations.


First read the label on the container and the vehicle manual. When engine and cooling system are cool, drain existing coolant (including the heater) as per the vehicle owners’ manual or by disconnecting lower radiator hose. After draining, flush system (including heater core) thoroughly with Cool Flush and reconnect hoses, drain plugs etc. Slowly add sufficient Cool Max 50 to fill the cooling system. Refer to the vehicle owners manual for the volume needed. To avoid possible incompatibility problems, do not mix with other coolant formulations.
Check level after the engine has reached operating temperature and allowed to cool again. Top up with Cool Max 50 if necessary. Any spillage on paintwork should be flushed off with water. Used coolant may be harmful to the environment (due to the extraction of heavy metals from the engine): contact regulatory authorities on appropriate methods of disposal
