How to properly add antifreeze: instructions with explanation

When operating a car, we will invariably face the need to add or change antifreeze. Many do not know how to properly add antifreeze, as a result, they carry out such service work on a hot and even running engine, which subsequently leads to critical malfunctions of the power unit. Let’s talk in more detail about how to properly add antifreeze, which will ensure the correct operation of the engine cooling systema and scrap cars for cash.

A bit of theory
Antifreeze is a coolant that constantly circulates in a closed circuit. The cooling circuit includes numerous channels in the engine, as well as a radiator, where the antifreeze is cooled directly. As the car is used, the performance characteristics of such a coolant deteriorate, as a result, not only a dense calcium deposit and sediment appears, but also metal elements begin to rust. Therefore, it will be necessary not only to regularly top up the coolant, but also to replace the antifreeze.

If the car owner neglects such a coolant service, this ultimately leads to overheating of the engine, which is fraught with critical engine breakdowns. Whereas all such problems could be avoided by timely replacing the antifreeze, and constantly monitoring the coolant level in the expansion tank. Remember that if the coolant begins to quickly leave the system, it is constantly necessary to top up antifreeze, this can indicate serious problems with the engine. In such a case, a comprehensive repair and diagnostics of the car is required.

Add antifreeze correctly
The car owner needs to remember that it is imperative to choose high-quality antifreeze, which is recommended by the manufacturer. It is not recommended to mix different types of antifreezes that differ in their performance characteristics. Therefore, the choice of such a coolant must be approached as responsibly as possible.

You can add antifreeze to the system only on a cold engine. If you perform such work on a hot engine, then cold antifreeze will get into the engine heated to high temperatures, and metal cracks appear due to the significant temperature difference, as a result, such an engine can even be replaced. Therefore, if necessary, add antifreeze, it is imperative to carry out such work on a cold engine.

Reasons for a decrease in the level of coolant
There can be many reasons why the coolant is leaking. This is damage to the connection of pipes, damage to the radiator, as well as loss of tightness of the engine cooling jacket. In the latter case, antifreeze can get into the oil or into the combustion chamber, as a result, the car owner will face serious and expensive repairs.

If damage to the pipes and radiators is noted, then in such a case, you can try to weld the existing damage, thereby somewhat reducing the cost of car repairs. It is still not worth leaving the solution of existing problems with the engine for later, as soon as you notice that the engine begins to quickly lose coolant, you should take the car to the service as soon as possible and repair it.

Let’s sum up
If you need to pour antifreeze into the expansion tank, then you need to remember that such work is performed exclusively on a cold engine. Also, the brand of antifreeze is selected without fail, which should be similar to the coolant poured into the engine and recommended by the automaker. Remember also that if the coolant level in your car engine starts to drop rapidly, then it is necessary to carry out the appropriate diagnostics and determine the cause of the existing problems.
