Ами виж сега, то може да се проверят сто неща, но виж какво пише в официален бюлетин на Мерцедес:

"The coolant temperature of MB vehicles may rise substantially above 100°C/212°F at high ambient temperatures while the vehicle is:

a) stopped
b) in city traffic ("stop and go")
c) when driving uphill
d) when driving at very high speed, i.e. with high engine load


Engine coolant temperature returns to "normal" upon returning to regular driving conditions. In individual cases, the temperature reading may approach the red field of the temperature gauge.

Provided the cooling system is well maintained and in good working order, such temperature levels do not create any danger for the engine and, therefore, give no cause for concern. The boiling point of the recommended coolant mixture (Refer to Service Information 20/9 and Service Microfiche group 20), is much higher than 1OO°C."

С две думи, ако всичко по охладителната система ти е наред, няма какво да се притесняваш от температури около 100°C.
