246 Checking and filling
sca lding from hot coolant by following
these steps .
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping flu id and steam by cover ing
the cap with a large, thick rag.
- Turn the cap slowly and very carefully
in a counter-clockwise direction while
applying lig ht, downwa rd pressure on
the top of the cap.
- To avo id being burned, do not spill an
tifreeze or coolant on the exhaust sys
tem or hot engine parts . Under certain
conditions, the ethylene glyco l in en
gine coolant can catch f ire.
- Antifreeze is poisonous . Always store an
tifreeze in its or iginal container and we ll
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".
@ Note
- Coolant pollutes the environment and
could cause an engine fire . Excess coo l
ant will be forced out through the pres
sure relief valve in the cap when the en
gine becomes hot.
- If, in an emergency, only water can be
added, the correct ratio between water
and antifreeze
c::> page 244 must be re
stored as soon as possible .
@ For the sake of the environment
Drained coolant should 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
T he radiator fan is driven by the engine via the
V-belt . The viscous clutch regulates the speed
of the fan according to the temperature of the
coolant. An auxiliary electric
radiator fan* switches on
and off depend ing on coolant temperature
and other vehicle operat ing condit ions .
After yo u sw itch the engine off, the auxiliary
f an can continue running for up to 10 minutes
- even with the ignit ion 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 i ntense sunlight.
_& WARNING
- To reduce the risk of personal injury nev
er touch the radiator fan.
- The auxiliary electric fan is temperature
controlled and can sw itch on suddenly
even when the engine is not running.
- The auxiliary radiator fan switches on au
tomatically when the engine coo lant
reaches a certain temperature and will
continue to run until the coolant temper
ature drops .
Brake fluid
Checking brake fluid level
