Cool Max 100

Description

This is a general purpose ready to use glycol based treatment for automotive cooling systems. Freezing point is -35 degrees C approx at 50% dilution and -15 degrees C at 35% dilution. Replace at 24 month / 60,000 km intervals. May be replaced more frequently depending on engine and driving conditions. Top up radiator as required to avoid rundown in concentration. This product contains a pH-buffered blend of  additives known  to  reduce the corrosion of steel, cast  iron,  aluminium alloy, brass, copper and solder.
This product exceeds the performance requirements of the following standards when assessed in hard water and  is made to General Motors Specification HN 2043

  *  ASTM D1384 " Corrosion Test for Engine Coolants in Glassware."

  *  ASTM D4340 "Corrosion of Cast Aluminium Alloys in Engine Coolants Under Heat Rejecting Conditions."

  *  ASTM D2570 "Simulated Service Corrosion Test for Engine Coolants."

  * ASTM D2809 "Cavitation Corrosion and Erosion Corrosion Characteristics of Aluminium Pumps With Engine Coolants."

  *  Australian/New Zealand Standard 2108.1:1997  "Engine Coolants Type A and Type B for Engine Cooling Systems."

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

Use

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 Max 100 and reconnect hoses, drain plugs etc. In a clean vessel mix Cool Max 100 at 35-50% with clean water and   slowly add sufficiently 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 prediluted  Cool Max 100 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

Safety

This product contains ethylene glycol and is poisonous if swallowed. Read Material Safety Data Sheet before use.  Avoid contact with the skin  and  eyes.  Keep out of reach of children.
