PRINZ Automotive tells you all the secrets of the coolant, which is essential for the proper functioning of the engine.

How is coolant protection measured?

The unit of protection is in degrees Celsius, not percentages. It is important to pay attention to this, because some brands will list the percentage of raw materials, which tends to mislead users. Take for example, the coolant -37 ° which contains 50% MEG (mono ethylene glycol), the scale is not identical.

Does the coolant only act as a “cooler”?

Coolants perform two essential functions, protection against freezing and at the same time protection against overheating. A coolant with a protection of -37°C, for example, also protects against overheating up to +135°C.

What role do the different colors of the liquid play?

Basically, a antifreeze has no color.
The manufacturers simply add dyes to identify them.
In this way, we can differentiate between “universal” antifreeze, which has a green color, and yellow antifreeze, which is recommended for Renault-Dacia vehicles, and pink antifreeze for Volkswagen vehicles. The best way to choose a antifreeze is to refer to the vehicle’s manual or to ask a professional for advice.
