Ardeca Alu-Freeze G40 is an engine coolant concentrate (antifreeze) based on monoethylene glycol. This product employs the latest antifreeze technology which combines the benefits of both organic technology & traditional mineral (silicate) technology. 

• Increased life time, allowing less frequent maintenance, thanks to the corrosion inhibitors which have a very low depletion rate.
• Thermal characteristics that permit effective engine cooling without boiling.
• Elimination of abrasives solids, which gives a better protection of the joints of the water pump.
• Superior short & long-term corrosion protection through combined use of organic acid and highly stabilized silicate additives, especially for aluminium engines.
• Environmentally friendly as free from borates, phosphates, nitrites & amines.
• Protection against frost, depending on the concentration chosen.
• Excellent antifoaming characteristics.
• Meets most European and International Standards.
• Backwards compatible with G11, G12+, G12++, G13
