6.3.2 Draining Cooling System6.3.1 Cleaning Intervals
● The degree of soiling of the cooler units is
dependent on the type of engine application.
● The danger of soiling is increased due to
residues of oil and fuel on the engine. Check
extra carefully, therefore, for leakages when
applications involve high dust fallout.
● More severe soiling can occur, e.g. in the case
of:
– Construction site application due to heavily
dust-laden air.
● In view of the varying conditions of application,
the cleaning intervals must be determined from
case to case. The cleaning intervals stated in
the table can be taken as guide values.
● Place tray under drain plug 1.
● Remove drain plug 1 and sealing ring below
coolant inlet.
● Drain coolant.
● Filling / bleeding as under 6.3.3
● Screw on drain plug 1 with new sealing ring
and tighten (see 9.2).
● Check for leaks.
● Fill with coolant and bleed cooling system
according to manufacturer’s instructions.

● Let engine run up to operating temperature
after each wet-cleaning procedure allowing
any remaining water to evaporate, thus
avoiding corrosion.
- with cold cleaning agent
● Spray engine with commercial cold cleansing
agent and let stand for about 10 min.
● Then spray clean with strong water jet (do not
spray water directly onto sensitive components
such as alternator, starter, wiring, electronic
components).
