2016 SKODA OCTAVIA engine coolant

WARNING■The blower should always be on to prevent the windows from misting.
Otherwise there is a risk of an accident.■
Under certain circumstances, air at a temperature of about 5 °C can flow
out of the vents when the cooling system is switched on.
Note
■ The air inlet in front of the windscreen must be free of e.g. ice, snow or
leaves to ensure that the heating and cooling system operates properly.■
After switching on the cooling Condensation from the evaporator of the air
conditioning may drip down and form a puddle below the vehicle. This is not a
leak!
■
If the coolant temperature is too high, the cooling system is switched off to
ensure that the engine cools down.

WARNING■The auxiliary heating must never be operated in closed rooms (e.g. garag-
es) – risk of poisoning!■
The auxiliary heating must not be allowed to run during refuelling – risk
of fire.
■
The exhaust pipe of the auxiliary heating is located on the underside of
the vehicle. If you want to use the auxiliary heating, do not park the vehicle
in places where the exhaust fumes can come into contact with flammable
materials such as dry grass, undergrowth, leaves, spilled fuel etc. - There is
a risk of fire.
CAUTION
The air inlet in front of the windscreen must be free (e.g. of ice, snow or
leaves) to ensure that the auxiliary heating operates properly.
Note
■ The auxiliary heating only switches the blower on, if it has achieved a coolant
temperature of approx. 50 °C.■
In the engine compartment, water vapour may form during the operation of
the heater.

WARNINGInformation for working in the engine compartment with the engine run-
ning■
If it is necessary to work on the engine with the engine running, beware
of rotating engine parts and electrical plants - There is a risk to life!
■
Never touch the electric wiring on the ignition system.
■
Avoid short circuits in the electrical system, particularly on the vehicle's

The capacity of the reservoir is about 3 litres or about 4.7 litres on vehicles that
have a headlight cleaning system 1)
.
Use a suitable windscreen washer fluid for the current or expected weather
conditions. We recommend that you use windscreen washer fluid from ŠKODA
Original Accessories.
CAUTION
■ If the vehicle is equipped with a headlight cleaning system, then only use
windscreen washer fluid types that do not attack the polycarbonate coating of
the headlights - otherwise there is a risk of damage to headlights.■
Do not remove the filter from the windscreen washer fluid reservoir when re-
plenishing it with liquid - otherwise the liquid transportation system might be
contaminated, which can cause the windscreen washer system to malfunction.

» Fig. 293 . If the oil level is below range
A
, oil
must be added.
Refilling

›
Add oil of the correct specification in portions of 0.5 litres » page 255.
›
Check the oil level.
›
Screw the lid of the engine oil filler closed carefully.
CAUTION
■
The oil level must never be below range A » Fig. 293 there is a risk of dam-
age to the engine as well as to the exhaust system.■
If a top up with oil is not possible or the oil level is above range
A
, 
stop
driving! Switch off the engine and seek assistance from a specialist garage.
NoteAn engine oil level which is too low is shown in the instrument cluster by the
warning light  illuminating and also indicated by the message » page 38.
Nevertheless, we recommend checking the oil level on a regular basis using
the dipstick.
Coolant
 Introduction
This chapter contains information on the following subjects:
Checking and refilling
257
The coolant helps to keep the engine temperature down, and consists of wa-
ter and coolant additive (with additives that protect the cooling system against
corrosion and prevent furring).
The proportion of coolant additive in the coolant must be 40 to 60 %.
The correct mix of water and coolant additive should be checked and if neces-
sary corrected by a specialist garage.
WARNING■ The following instructions must be followed at all times when working on
the engine compartment » page 252.■
Never open the end cover of the coolant expansion reservoir while the
engine is still warm. The cooling system is pressurised - risk of scalding or
injury from splashes of coolant!
■
To protect against the coolant splashing, cover the cap with a cloth when
opening.
■
Coolant and coolant fumes are harmful - avoid contact with the coolant. If
the coolant comes into contact with the eye or skin, wash the affected area
with plenty of water for several minutes, and where appropriate seek medi-
cal help.
CAUTION
Do not cover the radiator and install any parts (e.g auxiliary lights.) in front of
the air intakes - There is a risk of the engine overheating.256General Maintenance

Checking and refillingFig. 294
Coolant expansion reservoir
Read and observe and on page 256 first.
Check and refill coolant under the following conditions.The vehicle is on a horizontal surface.
The engine is not warm (if the engine is warm the result of the check may
be wrong).
The engine is turned off.
Check the coolant level - The coolant level must lie between the marks
A
and
B
» Fig. 294. If the coolant level is below the mark
B
, top up with coolant.
Refilling
The reservoir must always contain a small amount of coolant »
.
›
Place a cloth over the cap of the coolant expansion reservoir and unscrew
the cap carefully .
›
Always top up using coolant of the correct specification.
›
Turn the cap until it clicks into place.
The specification for the coolant is shown in the coolant expansion reservoir
» Fig. 294 .
If the specified coolant is not available, then refilling only with distilled or puri-
fied water, and get a specialist garage to correct the water-coolant additive
mix as soon as possible.
CAUTION■ If the expansion tank is empty, do not top up with coolant. The system could
aerate - There is a risk of engine damage!  Stop driving! Switch off the en-
gine and seek assistance from a specialist garage.■
Do not fill the coolant above the mark
A
» Fig. 294 . The coolant could, when
heated, be expelled from the cooling system - There is a risk of damage to the
engine parts.
■
If it is not possible to add coolant, 
stop driving! Switch off the engine and
seek assistance from a specialist garage.
■
A coolant additive which does not correspond to the correct specification can
reduce the anti-corrosion effect of the cooling system - risk of damage to the
cooling system and the engine.
■
If distilled (purified) water has been used to top up, the coolant should be re-
placed by a specialist garage - risk of engine damage.
■
A loss of coolant indicates leaks in the cooling system - risk of engine dam-
age. Top up with coolant and then seek assistance from a specialist garage.
Note
A coolant level which is too low is indicated in the instrument cluster by the
warning light and shown by the relevant message » page 38. We still recom-
mend inspecting the coolant level directly at the reservoir from time to time.
Brake fluid
