Draining and filling coolant
40
Fill / bleed the cooling system (only when engine has cooled down)
The cooling system of the engine is to be filled with a mixture of drinking water from the mains and
antifreeze based on ethylene glycol and / or anticorrosion additive.
Caution:
Use only approved fuels, lubricants etc. (see brochure “Fuels, lubricants etc.”). Otherwise the
liability for defects will become null and void!
Do not put cold coolant into an engine which is
warm from operation. Ensure that the mixing ratio
“water−antifreeze” is preserved.

D Connect pump À (51.05100−7007) up to
coolant elbow using hose nipple Á
(51.98131−6002) and start filling operation by
actuating the button.
Note:
The engine may be filled up with coolant
either by means of a pump or via the filler
neck Ä.
D The water-cooled exhaust manifold and the
rear intercooler must be vented during the filling
process. To this end, the exhaust manifold Â
and the rear intercooler à (D 2842LE433) are
fitted with vent screws which must remain open
until the coolant flows free from bubbles or until
the coolant reaches the filler neck Ä
(depending on the mounting position).
D Remove hose nipple Á and fit a plug.
D Let engine run at a speed of 1200 rpm until the
thermostats open
D Switch off engine, carefully turn cap Ä with
safety valve to the first detent to relieve
pressure and then carefully remove cap and top
up with coolant
D Bleed the exhaust pipes once again
Danger:
Risk of scalding!
D Before the engine is next put into operation
(with the engine cold) check the coolant level
and top up if necessary
D Repeat this procedure until no more coolant
can be added
