Facts
Glycol is used in the engine cooling system mixed with water. A mixture of glycol and water only freezes at -40 degrees, which prevents freezing. It is important to carry out an annual glycol check.
The glycol is also effective against rust. There is a risk that the engine will overheat if the fluid level is too low in the cooling system. The radiator itself does not require any maintenance, but instead the focus is on ensuring that there are correct fluid levels.
