2007 SKODA OCTAVIA TOUR engine coolant

142GENERAL MAINTENANCECooling system
In normal operating conditions the cooling
system requires practically no mainte-
nance. The coolant consists of water and
a 40 % concentration of coolant additive.
This mixture not only offers the necessary
antifreeze protection down to -25 °C, but
also protects the cooling and heating sys-
tem from corrosion. In addition, it prevents
the formation of scale and increases the
boiling point of the coolant.
For this reason, the concentration of cool-
ant should also not be reduced during the
summer or in warm countries by topping up
with water. The coolant additive concen-
tration should be at least 40 %.
If greater antifreeze protection is required
for climatic reasons, the concentration of
coolant additive can be increased, but only
up to 60 % (antifreeze protection down to
about -40 °C). A higher concentration re-
duces the antifreeze protection and the
cooling efficiency is also impaired.
Cars for export countries with a cold climate
(e.g. Sweden, Norway, Finland) are factory-
filled for antifreeze protection down to about
-35 °C.
CoolantThe cooling system is factory-filled with the
coolant TL 774-F (G12 PLUS), lilac in col-
our.
We recommend using the same fluid for
topping up the system - G 12 PLUS (lilac
in colour).
In the event that it is necessary to top up
the system with a different coolant or if there
are any unclear aspects, please contact
your Škoda Dealer.
The correct coolant is available from your
Škoda Dealer.
Other coolant additives may consider-
ably impair the corrosion protection pro-
vided.
Any corrosion damage arising from the
use of another additive may result in a
loss of coolant and consequently in
major engine damage.
The fluid level should always be between
the „MAX“ and „MIN“ markings. If the level
has dropped below the „MIN“ marking, the
power steering should be inspected by a
Škoda Dealer. It is not sufficient simply to
top up the hydraulic fluid.
Note
When the engine is not running (e.g. when
the car is being towed or the ribbed belt is
broken) the power steering does not oper-
ate. The car can still be fully steered how-
ever, although greater physical effort is re-
quired for steering.

GENERAL MAINTENANCE
Loss of coolantA loss of coolant is first and foremost an
indication of a leak. In this case, the cool-
ing system should be inspected by a Škoda
Dealer. It is not sufficient merely to top up
the coolant.
If there is no leak in the system, losses may
also occur if the coolant boils as a result of
overheating and is forced out of the cool-
ing system.
If it is not possible to find and rectify the
cause of overheating, contact a Škoda
Dealer as soon as possible - otherwise
major engine damage may result.Topping up coolantFirst of all, switch off the engine and allow
it to cool down. Then, place a rag around
the cap of the expansion reservoir and
carefully unscrew the cap.Warning
Do not open the cap of the expansion
reservoir when the engine is hot -
risk of scalding. The cooling system
is pressurized!
Checking coolant levelThe coolant reservoir is located in the right
of the engine compartment.
The coolant level can be correctly checked
only when the engine is not running.
When the engine is cold, the coolant in the
expansion reservoir must be in the area of
the „ MIN“ mark and the crosshatched area.
When the engine is warm, the coolant level
may be slightly above the crosshatched
area. If, in exceptional cases, it is only possible
to top up the system with water, the correct
mixture concentration should be restored
without delay by using the specified cool-
ant additive.
If there is a major loss of coolant, do not
pour in coolant until the engine has cooled
down to avoid any engine damage.
Do not top up beyond the crosshatched
area!
Excess coolant is forced out of the cooling
system by the pressure relief valve in the
cap of the expansion reservoir when the
coolant heats up.
Screw the reservoir cap tight!
If the event that you do not have enough
coolant,
do not drive any further. Switch
off the engine and contact a Škoda Dealer
for professional assistance, otherwise there
is a risk of serious engine damage.

144GENERAL MAINTENANCE
Drained coolant should not nor-mally be re-used but should be dis-
posed of by complying with environmen- tal protection regulations.
Radiator fanThe radiator fan is driven by an electric mo-
tor and controlled by a thermostatic switch
in line with the coolant temperature.
Warning
After the engine has been switched
off, the fan may continue running for
a while - even if the ignition is swit-
ched off. It may also start to run again
suddenly after a short time if
- the coolant temperature increases due to heat build-up
- when the engine is hot and the en- gine compartment is heated addi-
tionally by strong sunlight.
Special care should therefore be
taken when working in the engine
compartment.
Brake fluidThe brake fluid reservoir is located in the
left of the engine compartment.Checking fluid levelThe fluid level should always be between
the „MAX“ and „MIN“ markings on the re-
servoir.
A slight drop in the fluid level occurs when
driving as a result of wear and tear and au-
tomatic slack adjustment of the brake pads.
This is perfectly normal.
Warning
The coolant additive and the coolant
are poisonous! Do not breathe in
coolant vapours, do not swallow
coolant, avoid contact with eyes and
skin.
If coolant splashes into your eye,
rinse out immediately with clear wa-
ter and contact a doctor.
If coolant is swallowed, you should
likewise contact a doctor. The cool-
ant additive should therefore be
safely stored in the original contain-
ers out of the reach of children.
If the coolant has to be drained out
of the cooling system of the car at
any time, it should be collected,
marked and likewise stored in a safe
place.
