It ensures optimum protection of all the metallic, rubber and plastic parts which are in contact with the engine coolant. Protectant, Coolant System, Automative Engine.

Sasol Coolant Conc 100 is dark green in colour.


Sasol Coolant Conc 100 is recommended as a year-round cooling system additive for all water-cooled internal combustion engines. It offers protection against:

  • Damage as a result of coolant freezing during inclement weather
  • Corrosion of the radiator, engine and other component surfaces exposed to the coolant

Features and Benefits

Depending on the degree of protection required, Sasol Coolant Conc 100 may be used in a mixture with water in ratios of between 1 : 3 and 1 : 1. It is recommended that the antifreeze in a cooling system be replaced annually. Before a cooling system is filled with Sasol Coolant Conc 100 it should be drained and thoroughly flushed with clean water. Do not top up with plain water but use the same mixture as used for the initial fill.
