Filling/Bleeding The Cooling System (Only When Engine Has Cooled Down) - Man D 2840 LE 403 Operating Instructions Manual

Filling / bleeding 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 ethylene glycole basis or anti-corrosion agent.
See Publication "Fuels, Lubricants and Coolants for MAN Diesel Engines".
Coolant must be added at the filler
neck only À (large cap). When topping
up do not add cold coolant if the engine is
still warm from operation. Ensure that the
ratio of water to anti-freeze is correct. Find
the cause of the loss of coolant and have
it eliminated.
D Remove cap À (large cap)
D Fill in the coolant slowly
D During the filling procedure the liquid-
cooled turbochargers and the inter-
cooler must be bled. For this there are
bleed screws on the diffusor Á and on
the intercooler Â. These must remain
open until coolant emerges without
bubbles or until the coolant level re-
aches the filler neck (depending on in-
stallation position)
D Let engine run at a speed of 2,000 rpm
for approx. 15 minutes
D Switch off engine, carefully turn cap À
with safety valve to the first detent to
relieve pressure and then carefully re-
move cap and top up with coolant
