COOLANT CHECK
In order to guarantee the lifetime and
quality of the product, thus to optimise
engine protection, regular coolant-
condition-analysis is advisable.
The quality of the product can be
determined by:
Visual check
Verify the outlook of the coolant
regarding colour and make sure that no
loose particles are floating around.
TOPPING UPCOOLANT
Verify if the engine cooling system is in
a good condition (no leaks, clean,...).
Check the condition of the coolant.
If the condition of the coolant is outside
the limits, the complete coolant should
be replaced (see section Replacing the
coolant).
Topping up the coolant with water only,
changes the concentration of additives
and is therefore not allowed.
REPLACING THE COOLANT
Drain
Completely drain the entire cooling
system.
Used coolant must be disposed or
recycled in accordance with laws and
local regulations.
Fill
To assure proper operation and the
release of trapped air, run the engine
until normal engine operation
temperature is reached. Turn off the
engine and allow to cool.
Recheck coolant level and add if
necessary.
Never remove the cooling system
filler cap while coolant is hot.
The system may be under
pressure. Remove the cap slowly
and only when coolant is at
ambient temperature. A sudden
release of pressure from a
heated cooling system can result
in personal injury from the
splash of hot coolant.
For topping up / replacing
coolant consult engine operation
manual.
Caution: do not top off when the
engine is hot.
