Engine coolant

Engine coolant

The engine can run smoothly thanks to the coolant. Antifreeze is really essential for proper engine operation. It keeps the engine at a good operating temperature by protecting it from freezing and overheating.

Checking the coolant level lets you know that a vehicle is properly protected and can operate safely. Changing the coolant when it is worn is considered essential for engine longevity.


Coolant plays an important role in the engine cooling system. That is why changing the coolant when it is used is considered a necessity. Using a drain, bleed and change station such as Flash Cooling® makes it possible to do this in minutes.

In addition, coolant is a special product. It requires precautions for its treatment, recycling and during its use. One of the particularities to remember concerning the coolant is that it only starts boiling from 100°C, just as for it to freeze, the temperatures must be really low.

The main function of the coolant is to keep the engine temperature constant. It prevents the engine from overheating or freezing.


In general for a vehicle, it is recommended to change the coolant every 50,000 kilometres or every 2 to 4 years depending on the manufacturer. This is because over time the coolant loses its qualities and properties.

The rate of pH decreases increasing its acidity. The glycol level also decreases, reducing the engine’s protection against frost. It is therefore imperative to replace it regularly. To carry out this emptying, there are draining, purging and replacement machines such as Flash Cooling®.

This type of station makes it possible to carry out the operation in a few minutes and without any dismantling on the vehicle. It is therefore no longer necessary to immobilize the vehicle for hours.
