Cooling system
Coolant
The job of the coolant is to cool the engine.
The cooling system does not require any maintenance under normal oper-
ating conditions. The coolant consists of water with a concentration of
antifreeze agent of 40 %. This mixture not only provides antifreeze protec-
tion down to -25°C but 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.
You must therefore not reduce the concentration of antifreeze agent in the
coolant by adding water, also not during the summer months or in coun-
tries with a warm climate. The concentration of antifreeze agent in the
coolant must be at least 40%.
You can increase the amount of antifreeze in the coolant iIf 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.
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.
Coolant
The cooling system is factory-filled with TL 774-F (G12 PLUS) coolant -
colour purple - .
We recommend that you use the same antifreeze agent - G12 PLUS
(purple in colour).
Please contact your Škoda dealer if you have any questions regarding the
coolant or if you wish to fill up with a different coolant.
Your Škoda dealer can also supply you with the correct coolant additives.
Caution
•
Other coolant additives may cause operational problems which,
in particular, 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
The coolant expansion bottle is located in the engine compart-
ment on the left.
– Switch the engine off.
