Car engine coolant - things to note
(Baonghean.vn) - Choosing the right and quality car coolant will ensure the efficiency of the cooling system, thereby helping the engine run smoothly in all weather conditions. Below are important notes about car coolant.
Uses of car coolant
 |
During vehicle operation, the fuel burned in the engine cylinder will generate a large amount of heat. Only a part of it is converted into work, the rest will be released into the air and contact with machine parts. Heat is also generated due to surface friction between other parts of the engine; too high temperature will have a negative impact on the performance, reduce the life of the engine, and even cause fire or explosion.
Therefore, car engine coolant plays an important role, it has the effect of quickly transmitting heat, helping the engine operate properly by removing excess heat, reducing overheating and sudden shutdown.
How often should the coolant be changed?
 |
Check the coolant level regularly, ensuring that the coolant level in the sub-tank is always between the “Full” and “Low” positions when the engine is cold.
The sub-tank cap and radiator cap must be opened to add water when the coolant level is lower than the “Low” mark.
Experts advise that after every 40,000 - 50,000 km of driving (about 2 - 3 years), drivers should change the coolant to ensure the most effective cooling capacity. For the first time changing, it can be longer than 50,000 km, but the next times should be regular at this frequency.
The darker the engine coolant the better?
 |
The color of the solution is simply a matter of mixing the ingredients, and does not mean that the darker the solution, the faster it will cool. It is best for drivers to use the type recommended by the manufacturer for their vehicle.
Can I use tap water instead of cool water?
 |
Purified water or natural water used in daily life contains many different compounds such as limestone residue, metal. Therefore, when entering the cooling system, at many altitudes, it can cause residue to form in the radiator, reducing heat dissipation efficiency.
In emergency cases where filtered water or mineral water is required, the coolant tank can still be filled, but then the service station must be immediately visited so that the staff can clean the radiator and fill it with the correct solution.
Notes on use and replacement of coolant Coolant has 4 colors: green, dark blue, red and pink. Each type of coolant has its own index of scale temperature or boiling temperature; green and red are LLC (long life coller), dark blue and pink are SLLC (super long life coller) Many vehicles clearly state whether the vehicle uses LLC or SLLC coolant. For diesel engines with silicon plugs in the engine, yellow water should not be used because organic acids will corrode these plugs after 130,000 - 160,000 km. Coolant will enter the lubrication system through the gaps and result in engine damage. In case the engine is hot due to loss of coolant, absolutely do not open the radiator cap, hot steam in the radiator can cause burns. Wait 15-20 minutes for the water to cool before opening the cap. Additional coolant additives should not be used as they may cause damage that will void the manufacturer's warranty. |
