Recommendation. The coolant level rises as the engine temperature increases and falls as it decreases. Therefore, the coolant level should only be checked when the engine has cooled down (after parking for at least 2-3 hours).
The coolant level in the expansion tank when the engine is not warmed up should be slightly above the mark indicated by the arrow.

Warning! Be careful not to unscrew the expansion tank cap on a hot engine - you can get burned by boiling liquid or steam!
If necessary, add coolant:
1. Unscrew the cap from the expansion tank of the cooling system.

2. Add coolant into the tank through a funnel.

3. Having brought the liquid level to the norm, tightly screw the expansion tank cap in the reverse order.
