Always use antifreeze 19 40 650 / 9194431 (red) and ensure that
the concentration is 50% water and 50% antifreeze. The antifreeze
does not just protect the entire cooling system from freezing, but
also protects all coolant-flushed parts from rust-corrosion/calcium
deposits. It is therefore important to add antifreeze, even in
tropical countries.
|
60. |
The water quality also plays an important role in addition to
the mix ratio. Water of drinkable quality usually meets these
requirements. The quality of purified sea water is inadequate!
|
61. |
Damage may also be caused to the engine if unauthorised
anti-freeze agent is used!
|
62. |
If radiator, cylinder head or cylinder head gasket have been
replaced the old coolant must not be re-used.
|
Important: Vehicles with air
conditioning: switch air conditioning off and set to ECO mode with
ECC
|
63. |

Warning: Cooling system is under
pressure
|
• |

expansion tank
|
65. |
Seal off cooling system
• |
Screw in coolant expansion tank cover
|
|
66. |
Start engine and allow to warm up
• |
Allow engine to warm up at idling speed of up to 2500 rpm until
first radiator fan setting switches on
|
|
67. |
Vent cooling system
• |
Allow engine to run for approximately 2 minutes at 2000 to 2500
rpm
Note: The air in the
cooling system is removed via the venting lines
|
|
68. |
Switch engine off and allow to cool
|
69. |
Check coolant level and also top up coolant to "COLD" mark
