2009 SKODA OCTAVIA heating

Inspecting and replenishing
230
Losses can only occur through the pressure
relief in the cap of the coolant expan-
sion bottle which is completely free of leak
s if the coolant boils as a result of over-
heating and is forced out of the cooling system.
WARNING
Read and observe the warning notes
⇒page 225, “Working in the engine
compartment” before working in the engine compartment.
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
⇒
page 229, fig. 212
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 the system, must comply with one specific specification
⇒page 228. Do not use an alternative additive if the coolant
additive G12 PLUS is not available in exceptional cases. Just top up the system with water and as soon as possible arrange ad
justment 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 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.
WARNING
•
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 original 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 of the engine and contact

and obtain professional assistance from a specialist garage.
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 comp
liance with environmental protection
regulations.

not correctly positioned, water can get into
the fuses and this results in a damage
to the vehicle!
