Pre Charge Red Anti-Freeze.
All anti-freezes consist of water and a spectrum of special additives. And this solution protects the car’s power unit from exceeding the temperature and corrosion of cooling system parts that is permissible for the engine operation. In addition, it also helps to warm up the motor in winter. If you try rubbing your fingers with antifreeze, you will find that it is fatty. These are special additives that serve to lubricate the elements of the cooling system (for example, the pump) and prevent the drying out of its rubber and plastic elements (nozzles, seals, etc.). From this it becomes clear that the protection of the power unit and the cooling system is not the last effect of the quality of the antifreeze.
We list the main properties of antifreeze:
1. Ability to resist negative temperatures while remaining in the liquid state;
2. Ability not to boil in a certain temperature range;
4. Anti-freeze should not foam;
5. Increased heat capacity and thermal conductivity;
6. Antifreeze should not be aggressive to the materials of cooling system parts;
7. The cooling liquid must remain in a stable state, whether it is operated in a cooling system or stored in a canister;
When is it necessary to replace the antifreeze in the car?
Over time, the characteristics of the antifreeze change due to the constant exposure to it of a high or low temperature. In addition, foreign substances enter the cooling system. All this leads to the fact that the cooling liquid begins to foam, the life of the antifreeze is about 60 thousand km. (or 2 years) for antifreeze labeled G11 and 200-250 thousand km (or 5 years) for antifreeze with markings G12, G13, but this is provided that all this time its density did not change. It is very important to make a regular replacement of the cooling liquid also because the additives contained in it, after multiple temperature changes (from minus ones to +120 and higher) lose their protective properties, and the antifreeze becomes more aggressive to the materials of the cooling system, the heat transfer of its environment changes.
