Coolants & Antifreeze | Eurol Lubricants

Importance of coolant

Coolant is an indispensable part of the cooling system. As its name suggest, the primary role of coolant is to keep the engine cool. It also helps to guard engine parts against freezing, limescale deposits, and rust formation.

Checking your coolant

Because coolant is important for engine cooling, it is important to keep your coolant at a good level. Especially if your coolant is leaking (if you have coolant leaks, use a sealer such as Eurol Radiator Sealer immediately). You can read the coolant level on the coolant tank in the car. The level is often shown by dashes with a minimum and maximum level. If the level is below or near the minimum level, it is necessary to top up the coolant. Be sure to refill coolant only when the engine is cold!

Difference between coolant and antifreeze

Coolant is a ready-made product consisting mostly of water and antifreeze, supplemented with some additives. As a result, coolants have solid frost protection down to, say, -26°C or -36°C. Antifreeze, on the other hand, is a pure product that still needs to be mixed with water. The advantage of antifreeze is that it offers protection at even lower temperatures. So you still need to mix antifreeze with water yourself, whereas coolant has already been mixed.

Types of coolant

Today there are several types of coolant available. The most common types are G11, G12, G13 and BS6580. In addition, coolant is often given a color, for example red coolant. But we also have pink, white/transparent, green or blue coolant.
