collect the fluid with suitable containers before open-
ing any compartment or disassembling any compo-
nent containing fluids.
Dispose of all fluids according to Local regulations and
mandates.
NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.
Clean the cooling system and flush the cooling
system before the recommended maintenance
interval if the following conditions exist:
•
The engine overheats frequently.
•
Foaming of the coolant is observed.
•
The oil has entered the cooling system and the

Note: When the cooling system is cleaned, only
clean water is needed when the ELC is drained and
replaced.
Note: Inspect the water pump and the water
temperature regulator after the cooling system has
been drained. This is a good opportunity to replace
the water pump, the water temperature regulator and
the hoses, if necessary.
