Ch e ck ing and filling
We recommend using only coolant addi-
tive
Gl2++, Gl3
or in an emergency
Gl2 +.
Do
not
use a different additive . In an emergency
use plain water unt il you can get the correct
additive and can restore the correct ratio. This
should be done as soon as possible .
If you have lost a cons iderable amount of
coolant, then you should add cold antifree ze
and cold water only when t he engine is cold.
Always use new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Ex-
cess coolan t will be forced out through the
pressure relief valve in the cap when the en-
gine becomes hot.
A
WARNING
- The cooling system is under press ure and
can get very hot. Reduce the risk of
sca lding from hot coolant by following
these steps.
- Turn off the eng ine and allow it to cool
down.
- Protect your face, hands and arms from
escap ing fluid and steam by covering
the cap with a large, thick rag.
- Turn the cap slowly and very carefully
in a counter-clockwise direct ion while
applying light, downward press ure on
the top of the cap.
- To avoid being burned, do not spill an-
tifreeze or coolant on the exhaust sys-
tem or hot engine parts. Under certain
conditions, the ethylene glycol in en-
gine coolant can catch fire.
- Antifreeze is poisonous. Always store an-
t ifreeze in its original container and well
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con-
tainer clear ly marked "poison".
- Do not add coolant if the expansion tank
is empty. Air could enter the cooling sys-
tem and damage the eng ine. If this is
the case, do not cont inue driving. Seek
professiona l assistance .
- Coolant pollutes the environmen t and
could cause an engine fire. Excess cool-
ant will be forced out thro ugh the pres-
sure relief valve in the cap when the en-
gine becomes hot.
- If, in an eme rgency, only wate r can be
added, the correct ratio between water
and antifreeze
c::>
page 228 must be re-
stored as soon as possible .
@
For the sake of the environment
Drained coolant shou ld not be reused . Al-
ways dispose of used coolant while observ-
ing all environmental regulations .
Radiator fan
The radiator fan switches on automatically by
itself.
An auxiliary electric radiator fan switches on
and off depending on coolant temperature
and other vehicle operat ing condit ions .
After you switch the engine off, the auxiliary
fan can continue running for up to 10 minutes
- even with the ignition off. It can even switch
on again later by itself
c::>
.&,
if
- the temperature of the engine coolant rises
due to the heat build-up from the engine in
the engine compartment, or
- the engine compa rtment heats up because
the vehicle is parked in intense sunlight.
A
WARNING
- To reduce the risk of personal injury nev-
er touch the radiator fan.
- The auxiliary electric fan is temperat ure
controlled and can switch on suddenly
even when the engine is not running.
- The auxiliary radiator fan switches on au-
tomatically when the engine coolant
reaches a certai n temperature and will
continue to run until the coolant temper-
ature drops.
