Skoda Octavia COMBI 2007 Owner's Manual page 216

Vehicles exported to countries with a cold climate (e.g. Sweden, Norway, Finland)
are already factory-filled with a coolant which offers 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 filled at the works with coolant (purple in colour), which
complies with the specification TL-VW 774 F.
We recommend that you use the same coolant additive - G12 PLUS (purple in
colour).
Please contact your Škoda Service Partner if you have any questions regarding the
coolant or if you wish to fill up with a different coolant.
Your Škoda Service Partner can also supply you with the correct coolant additives.
Caution
•
Other coolant additives may cause operational problems which, in partic-
ular, involves significantly reducing 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.
Inspecting the coolant level

expansion bottle
Driving Tips General Maintenance
The coolant expansion bottle is located in the engine compartment on
the right.
– Switch the engine off.
– Open the bonnet ⇒
in "Working in the engine compartment" on
page 210.
– Check the level of coolant in the coolant expansion bottle
The coolant level when the engine is cold must lie between the
A a
(MIN) and (MAX) markings. The level may also rise slightly above
A a
the (MAX) marking when the engine is warm.
If the coolant level in the reservoir is too low, this is indicated by the warning light
⇒ page 28. We nevertheless recommend inspecting
in the instrument cluster 
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. 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 expan-
sion bottle which is completely free of leaks 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 210, "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.
