SERVICE AND MAINTENANCE
6.3 Cooling System
6.3.1 Cleaning Intervals
The amount of contamination in the
cooling system depends on the
engine application.
Spilled oil or fuel on the engine
increases the risk of contamination.
Be especially careful if the engine
is used in dusty environments.
Because applications vary, cleaning
intervals have to be determined from
case to case. The cleaning intervals
given in the table on the below can be
used as a guide.
Serious contamination can occur,
for example:
- on construction sites where there is
a high level or air borne dust.
- in harvesting applications where
here are high concentrations of chaff
and chopped straw in the vicinity of
the machine.
5.1.24
Clean the engine as described in 6.8.1.
