Inspecting and replenishing


In view of the problems involved in prop erly disposing of old oil, the necessary
special tools and the knowledge required for such work, we recommend that you have
the oil and oil filter change carried out by an authorised Škoda Service Partner.Note
After your skin has come in contact with th e oil, you must thoroughly wash your skin.Cooling systemCoolant
The job of the coolant is to cool the engine.The cooling system does not require any maintenance under normal operating condi-
tions. The coolant consists of water with a concentration of coolant additive of 40 %.
This mixture not only provides antifreeze protection down to -25°C but also protects
the cooling and heating system from corrosion. It also prevents the formation of scale
and significantly increases the boiling point of the coolant.
You must therefore not reduce the concentration of antifreeze agent in the coolant by
adding water, also not during the summer mo nths or in countries with a warm climate.
The concentration of coolant additive in the coolant must be at least 40%.
You can increase the amount of antifreeze in the coolant if a higher concentration of
antifreeze is necessary for cl imatic reasons but only up to 60% (antifreeze protection
down to approx. -40°C). The antifreeze prot ection tails off above that concentration.
Vehicles exported to countries with a cold climate (e.g. Sweden, Norway, Finland) are
already factory-filled with a coolant which of fers antifreeze protection down to about
-35°C. In these countries the concentration of coolant additive should be at least 50%.
Coolant
The cooling system is factor y-filled with coolant (purple in colour), which complies
with the specification TL-VW 774 G.
We recommend that you use the same coolan t additive - G13 (purple in colour) - for
topping up the system. Please contact an authorised Škoda Serv
ice Partner if you have any questions
regarding the coolant or if you wish to fill up with a different coolant.
An authorised Škoda Service Partner can also supply you with the correct coolant addi-
tives.

Caution

Other coolant additives may cause operat ional problems which, in particular,
involves significantly reduci ng the anticorrosion effect.

Any faults or problems resulting from corrosion may cause a loss of coolant
and, as a consequence of this, result in major engine damage.Petrol engines

Technical Data
Note
On vehicles which are fitted with an indepe ndent auxiliary heating and ventilation, the
volume of the coolant is greater by approx. 1 ltr.Inspecting the coolant levelThe coolant expansion bottle is located in the engine compartment on the right.
– Switch the engine off.
– Open the bonnet page 196.
– Check the level of coolant in the coolant expansion bottle fig. 164 . The coolant
level when the engine is cold must lie between the (MIN) and (MAX) mark-
ings. The level may also rise slightly above the (MAX) marking when the engine
is warm.
If the coolant level in the reservoir is too lo w, this is indicated by the warning light in
the instrument cluster page 31, “Coolant temperature/coolant level ”. We never-
theless recommend inspecting the coolant leve l 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. You should
not merely top up the coolant in the reservoir. It is also important to have the cooling
system inspected without delay by a specialist garage. Losses can only occur through the pressure
relief in the cap of the coolant expansion
bottle which is completely free of leaks if the coolant boils as a result of overheating
and is forced out of the cooling system.
WARNING
Read and observe the warning notes page 197, “Working in the engine
compartment” before working in the engine compartment.
Caution
One should contact a specialist garage as s oon as possible if the source of overheating
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 fig. 164 and
unscrew the cap carefully by turning it to the left .
–Top up the coolant.
– Screw the cap tight until it is heard to lock.
The coolant which you use for replenishing th e system, must comply with one specific
specification page 200. Do not use an alternative additive if the coolant additive
G13 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 addi-
tive again by a specialist garage.
Only use fresh coolant for topping up the system.
Do not fill up over the “MAX” marking! Excess coolant 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.

Inspecting and replenishing
202WARNING

The cooling system is pressurized! Do not open the cap of the coolant
expansion 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 yo ur eyes, rinse out your eyes immedi-
ately 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.Caution
Do not continue your journey if for some reason it is not possible under the
conditions prevailing to top up with coolant. Switch the engine off and obtain
professional 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 beca use 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!Brake fluidInspecting the brake fluid levelThe brake fluid reservoir is located on the left of the engine compartment. The brake
fluid reservoir on right-hand steering models is positioned on the other side of the
engine compartment.
– Switch the engine off.
– Open the bonnet page 196.
– Inspect the brake fluid level in the reservoir fig. 165 . The level must be between
the “MIN” and “MAX” markings.
A slight drop in the fluid level results when driving due to normal wear-and-tear and
automatic adjustment of the brak e pads, and is perfectly normal.
There may be an indication of a leak in th e brake system, however, if the fluid level
drops significantly within a short time or if it drops below the “MIN” marking. If the
brake fluid level is too low, this is indicated by the warning light page 34, “Brake
system ” lighting up in the instru ment cluster. In this case stop immediately and do
not drive any further! Obtain professional assistance.
