Common theory questions

What should you put in the car's cooling system?

You should put coolant fluid in the car's cooling system. Coolant fluid should consist of half water and half glycol and is easy to refill if the coolant level is too low. Coolant fluid can also be purchased diluted (ready-mixed).

Glycol protects against rust and prevents freezing, so it is especially important to check the coolant level during the winter.
