Radiator systems of petrol, diesel, LPG and CNG-fuelled engines in most passenger cars, trucks and buses.

Radiator systems of modern aluminium alloy engines.

Radiator systems of diesel engines fitted with cast iron cylinder liners.

Caution: Sinopec Environmentally Friendly Engine Coolant YF-2A is not suitable for use in passenger cars and light commercial vehicles that have zinc or zinc-alloy type components in the cooling system, for example, earlier models of Holden Commodore in Australia. It is, however, suitable for use in most passenger cars and light-duty commercial vehicles.


The advanced anti-corrosion system provides excellent protection against crevice corrosion in aluminium and cavitation corrosion erosion in cast iron, protecting the radiator components and ensuring longer life.

The non-silicate formulation protects against the formation of gels and deposits, even in the presence of hard water, ensuring improved coolant stability and longer effective coolant life.

Excellent heat transfer properties enable high temperature engine parts (especially the aluminium heat-transfer surfaces found in some modern engines) to be effectively cooled and protected from damage.

Can offer a single coolant/anti-freeze for use in a wide range of vehicles, so ideal for mixed fleet use.

Fully compatible with rubber tubing and sealing materials, and so prolongs the service life of water pump and seals.

Good stability enables the product to be stored year round without problems.

This environmentally friendly product contains no harmful, toxic or carcinogenic chemicals, and is not damaging to water or soil ecosystems.
