coolant reservoir SKODA SUPERB 2009 Owner´s Manual

CAUTION■Just filling the tank once with diesel fuel that does not comply with the
standard, can cause severe damage to parts of the engine, the fuel and ex-
haust system!■
If a different fuel other than diesel fuel, which complies to the above men-
tioned standards (e.g. petrol) is used, do not start the engine or switch on the
ignition! Engine parts could be significantly damaged!
■
Water which has collected in the fuel filter can cause engine faults.
CAUTION
■ The vehicle cannot be operated with biofuel RME, therefore this fuel must
not be filled in the tank and used for driving the vehicle. The use of biofuel
RME can cause considerable damage to parts of the engine or fuel system.■
Do not mix any fuel additives, so-called “flow improvers” (petrol and similar
agents), into the diesel. This can result in considerable damage to parts of the
engine or the exhaust system!

188WARNINGInjuries or scolding or risks of accident or fire may occur when working in
the engine compartment. For this reason, it is essential to comply with the
warning instructions outlined below and with the general applicable safety
rules. The engine compartment of your car is a hazardous area!WARNINGInstructions before beginning work in the engine compartment■Turn off the engine and withdraw the ignition key.■
Firmly apply the handbrake.
WARNING (Continued)■ If the vehicle is fitted with a manual gearbox, move the gearshift lever in-
to Neutral, or if the vehicle is fitted with an automatic gearbox, move the
selector lever into position P.■
Allow the engine to cool.
■
Never open the bonnet if you can see steam or coolant escaping from the
engine compartment – risk of scalding! Wait until no more steam or coolant
is escaping.
WARNINGInformation for working in the engine compartment■Keep all people, especially children, away from the engine compartment.■
Never touch the radiator fan while the engine is still warm. The fan might
suddenly start running!
■
Do not touch any hot engine parts – risk of burns!
■
The coolant is harmful to health.
■
Avoid contact with the coolant.
■
Coolant vapours are harmful to health.
■
Never open the end cover of the coolant expansion reservoir while the
engine is still warm. The cooling system is pressurized!
■
When opening the end cover of the coolant expansion reservoir, cover it
with a cloth to protect your face, hands and arms from hot steam or hot
coolant.
■
If any coolant splashes into your eyes, immediately rinse out your eyes
with clear water and contact a doctor as soon as possible.
■
Always keep the coolant in the original container, safe from people who
are not completely independent, especially children - there is a danger of
poisoning!
■
Consult a doctor immediately if coolant is swallowed.
■
Never spill fluids on the hot engine. Such fluids (e.g. the antifreeze con-
tained in the coolant) may ignite!
WARNINGInformation for working in the engine compartment with the engine run-
ning■
Pay particular attention to rotating engine parts (e.g. V-ribbed belt, gen-
erator, radiator fan) and the high voltage ignition system – risk to life!
■
Never touch the electric wiring on the ignition system. 

Note
The location of the inspection points in the engine compartment of petrol and
diesel engines is practically identical.
Radiator fan
Read and observe
and on page 186 first.
The radiator fan is powered by an electric motor. Operation is controlled ac-
cording to the temperature of the coolant.
123456WARNINGAfter switching off the ignition, the fan may intermittently continue to op-
erate for approx. 10 minutes.
Windscreen washer system
Fig. 165
Engine compartment: Wind-
screen washer fluid reservoir
Read and observe and on page 186 first.
The windscreen washer fluid reservoir is located in the engine compart-
ment » Fig. 165 .
This contains the cleaning fluid for the windscreen or rear window and for the
headlight cleaning system.
The capacity of the reservoir is about 3 litres or about 5.5 litres on vehicles that
have a headlight cleaning system 1)
.
Clear water is not sufficient to intensively clean the windscreen and head-
lights. We recommend using clean water together with a screen cleaner from
the range of ŠKODA Original Accessories (with antifreeze in winter), which will
remove any stubborn dirt.
The washing water should always be mixed with antifreeze in winter even if
the vehicle has heated windscreen washer nozzles.
Under exceptional circumstances, methylated spirits can also be used if no
screen cleaner with antifreeze is available. The concentration of methylated
spirits must not be more than 15 %. The freeze protection at this concentration
is sufficient only to -5 °C. 
1)
In some countries, 5.5 ltr. applies for both variants.

The coolant expansion reservoir is located in the engine compart-
ment » Fig. 167 .
Explanation of graphic » Fig. 167
Mark for the maximum permissible coolant level
Mark for the lowest permissible coolant level
The coolant level should be kept between the marks
A
and
B
.
If the coolant level is above the mark
A,
no coolant may be topped up.
If the coolant level is below the mark
B,
the coolant must be topped up.
Checking the level
›
Switch off the engine.
›
Open the bonnet.
›
Check the level of coolant in the coolant expansion bottle. » Fig. 167.
Check the coolant level only when the engine is cold.
ABIf the engine is warm, the test result may be inaccurate. The level can also be
above the mark A » Fig. 167 .
If the coolant level in the coolant expansion tank is too low, this is indicated by
the warning light 
illuminating in the instrument cluster » page 36, 
Cool-
ant . We still recommend inspecting the coolant level directly at the reservoir
from time to time.
Loss of coolant
A loss of coolant is first and foremost an indication of a leak in the system. Do
not merely top up the coolant. Have the cooling system checked by a specialist
garage.
Replenishing
Read and observe
and on page 191 first.
The coolant expansion tank must always contain a small amount of cool-
ant » page 191, in section Introduction .
›
Switch off the engine.
›
Allow the engine to cool.
›
Place a cloth over the cap of the coolant expansion tank and carefully un-
screw the cap.
›
Replenish the coolant.
›
Turn the cap until it clicks into place.
CAUTION
■ Only top up with new coolant.■Do not use an alternative additive if the specified coolant is not available. In
this case, use only water and have the correct mixing ratio of water and cool-
ant additive restored by a specialist garage as soon as possible.
