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.
Oil and fuel residues on the engine in-
crease the risk of contamination. There-
fore pay special attention to leaks if the
engine is used in dusty environments.
Serious contamination can occur, for ex-
ample:
- On construction sites where there is a
high level of air-borne dust.
- In harvesting application where there are
high concentrations of chaff and chopped
straw in the vicinity of the machine.
Because applications vary, cleaning inter-
vals have to be determined from case to
case. The cleaning intervals given in the
table on the right can be used as a guide.
