Radiator Fan - Skoda Superb Owner's Manual

Caution
One should contact a specialist garage as soon as possible if the source of over-
heating itself cannot be determined and removed, since there may be grave
damage to the engine.
Replenishing the coolant
– Switch the engine off.
– Allow the engine to cool down.
– Place a cloth over the cap of the coolant expansion reservoir
and unscrew the cap carefully by turning it to the left 
fig. 187
– Top up the coolant.
– Screw the cap tight until it is heard to lock.
The coolant which you use for replenishing the system, must comply with one
specific specification  page 205, "Coolant". Do not use an alternative additive if
the specified coolant additive is not available in exceptional cases. Just top up the
system with water and as soon as possible arrange adjustment to correct the
mixing ratio of water and coolant additive again by a specialist garage.
Only use fresh coolant for topping up the system.
Do not fill the coolant above the mark
which is heated up is forced out of the cooling system through the pressure relief
valve in the cap of the coolant compensation bottle.
Wait until the engine has cooled down for a system which has suffered a major loss
of coolant before pouring in coolant. This is necessary to avoid engine damage.
WARNING

The cooling system is pressurized! Do not open the cap of the coolant expan-
sion bottle if the engine is still hot - risk of scalding!

The coolant additive and thus all of the coolant is harmful to your health.
Avoid contact with the coolant. Coolant vapours are also harmful to the health.
It is important, therefore, to always safely store any coolant additive in its orig-
inal container out of the reach of children - risk of poisoning!

If any splashes of coolant get into your eyes, rinse out your eyes immediately
with clear water and contact a doctor as soon as possible.

You should also consult a doctor without delay if you have inadvertently
swallowed coolant.

Driving Tips
Caution
Do not continue your journey if for some reason it is not possible under the condi-
tions prevailing to top up with coolant. Switch the engine off and obtain profes-
sional assistance from a specialist garage, otherwise it could lead to severe engine
damage.
For the sake of the environment
Do not re-use coolant if it is necessary to drain the coolant in the system. It should
be collected and disposed of in compliance with environmental protection
regulations.

Radiator fan

The radiator fan may switch on suddenly.
The radiator fan is driven by an electric motor and controlled according to the
coolant temperature.
The radiator fan may continue running for up to 10 minutes after the engine has
been switched off - even if the ignition is also off. It may also switch on suddenly
after a certain time, if

the coolant temperature has risen because of an accumulation of heat or

the warm engine compartment is heated up additionally by strong sunlight.
WARNING
You must therefore be aware when working in the engine compartment that the
fan may switch on suddenly - risk of injury!
