Inspecting and replenishing 229
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.
Inspecting the coolant level
You must therefore not reduce the concentration of antifreeze agent in the coolant
by adding water, also not during the summer months 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 climatic reasons but only up to 60% (antifreeze
protection down to approx. -40°C). The antifreeze protection tails off above that
concentration.

bottle
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 %.
The coolant expansion bottle is located in the engine compartment on
the right.
Coolant
The cooling system is factory-filled with coolant (purple in colour), which complies
with the specification TL-VW 774 G.

We recommend that you use the same coolant additive - G12 PLUS-PLUS (purple
in colour) for topping up the system.
Check the level of coolant in the coolant expansion bottle ⇒ fig. 212.

(MIN) and A (MAX) markings. The level may also rise slightly above
a
the A (MAX) marking when the engine is warm.
An authorised Škoda Service Partner can also supply you with the correct coolant
additives.
If the coolant level in the reservoir is too low, this is indicated by the warning light
in the instrument cluster ⇒ page 36, “Coolant temperature/ Coolant quantity ”.
We nevertheless recommend inspecting the coolant level directly at the reservoir
from time to time.
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.
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.
