°
C, allow engine to cool down at least to ambient
temperature.
Check coolant level and if necessary top up coolant to max. cold
fill level (see marking on expansion tank).
Note:
The tank mark indicates the fluid level at approx. 20
°
C.
Use recommended coolant only.
Black expansion tank:
Allow engine to cool down before checking coolant level. Coolant
temperature must not exceed 30
°
C. If ambient temperature
exceeds 30
°
