Coolant is one of the essential products for the daily maintenance of trucks, with the rise of domestic brands, many cardholders have begun to choose the oil produced by unified petrochemical as the daily maintenance oil of trucks. Some cardmates said that when buying coolant, they found that there are several coolants that are also the supreme unified series, how should they choose?
At present, the commercial vehicle supreme unified coolant produced is divided into three types: hybrid organic OAT heavy-duty coolant, fully compatible long-life heavy-duty coolant and light truck diesel general coolant products.
First of all, let’s first look at the mixed organic OAT heavy-duty coolant, its replacement cycle can reach 200,000 kilometers, the freezing point is divided into -25, -35, -45 °C three, are the use of excellent grade ethylene glycol and compliant additives. At the same time, it has six functions of antifreeze, anti-boiling, anti-corrosion, anti-rust, anti-scale and anti-bacteria, and has a good anti-corrosion effect on copper, aluminum, tin and other metals, and also has good thermal conductivity, which can support the daily use of light trucks and heavy trucks.
Secondly, the freezing point of fully compatible long-life heavy-duty coolant is only -45 °C, and the product formula adopts binary organic carboxylic acid and fatty acid compound technology, which can provide excellent protection and anti-rust ability for various metal parts in the cooling system of heavy-duty trucks, and the longest service life can reach 600,000 kilometers. It has better protection functions in antifreeze, anti-boiling, anti-corrosion, anti-rust, anti-scale and anti-bacteria, which can effectively inhibit the high-temperature heat transfer corrosion of the engine aluminum alloy cylinder head, and has excellent performance in the corrosion resistance of water pump and cylinder liner cavitation. It will not damage the sealing material of the water pump, can extend the service life of the water pump, belongs to environmentally friendly coolant, suitable for the use of China VI commercial vehicles, and is produced according to the standard of GB 29743-2013.
In addition, it is the light truck diesel general coolant, this product we can see from the product name that it contains the keyword “light truck”. Before the launch of light truck series maintenance fluid by Unified Petrochemical, the maintenance of light trucks are the use of heavy truck oil, due to the huge difference in the working conditions of the two models, light trucks long-term use of heavy truck oil to maintain greatly reduced is the service life of light trucks.
After the launch of this light truck diesel general coolant product does solve the problem of light truck maintenance for light truck owners, it is completely designed in accordance with the working conditions of light trucks in product formula, the product will be heavy-duty and light-duty engines for the use of coolant requirements are compatible, can support diesel and gasoline engine use. Especially for wet cylinder liners has a significant protective effect, can effectively resist “cavitation”, extend the overall service life of the vehicle, and provide excellent anti-corrosion inhibition protection for solder, brass, copper, cast iron, steel and other metals. It can reduce the generation of impurities during the use of the product, not easy to cause water tank scaling, and support the vehicle cooling system to maintain stable working efficiency for a long time.
The above three supreme unified series coolants are suitable for commercial vehicles, which one should be bought, I believe that after reading the above content, cardholders have already known in their minds, these coolants can be bought in the dealer stores of unified petrochemical.
