Automotive Sundries - Antifreeze NF


Castrol Anti-freeze NF is a balanced formulation of mono ethylene glycol and corrosion inhibitors. Castrol Anti-freeze NF is a nitrite,
phosphate and amine-free coolant containing ethylene glycol. It has been developed to meet the growing demand from manufacturers
for a higher performance coolant that minimises environmental impact.


Aqueous solutions of Castrol Anti-freeze NF act as both an antifreeze and coolant and impart very good anti-corrosion protection to all
metal parts found in the cooling systems of internal combustion engines.


Castrol Anti-freeze NF provides excellent protection against corrosion, and because it contains no phosphate, the problems of
deposits in some modern performance engines are eliminated. In addition to providing excellent corrosion and low temperature
protection, the use of the recommended level of anti-freeze will significantly reduce the likelihood of wet cylinder liner pitting due to "
cavitation erosion". Cavitation erosion is caused by the implosion of air bubbles present in the coolant and which are attracted to the
liner outer surface. These bubbles implode, resulting in the removal of minute amounts of liner material - this, if allowed to continue
unchecked, will result in liner porosity and severe engine damage.
