56.   Attach air intake pipe to air intake hose and turbocharger 3.5 Nm
57.   Attach bulkhead cover plate insulation 4 Nm .
58.   Connect ground cable to battery.
59.   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.   Open cooling system
Warning:   Cooling system is under pressure
•   Unscrew coolant expansion tank cover
64.   Fill with coolant up to lower venting line (1) at coolant 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
