Fill / bleed the cooling system (only when engine has cooled down)
Fill the cooling system of the engine with a mixture of drinkable tap water and anti-freeze
agent on the ethylene glycole basis or anti-corrision agent.
See Publication “Fuels, Lubricants and Coolants for MAN Diesel Engines”.
Coolant must be added at the filler neck only (large cap).
Do not put cold coolant into an engine which is warm from operation.
Ensure that the ratio of water to anti–freeze is correct.
D Remove cap (large cap)
D Slowly fill up with coolant until correct
coolant level is reached
D Refit end cover

Danger:
If, in an exceptional case, the coolant level has to be checked in an engine that
has reached operating temperature, first carefully turn the cap with safety valve
to the first stop, let off pressure, then open carefully.
