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 su mmer 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 an tifreeze protection tails off above that concentration.
Vehicles exported to countries with a co ld climate (e.g. Sweden, Norway, Finland) are already factory-filled with a coolant wh ich offers antifreeze protection down to about -35°C. In these countries the concentr ation 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 antifreeze agent - G12 PLUS (purple in colour).
We recommend that you contact your Škod a Service Partner if you have any ques- tions regarding the coolant or if you wish to fill up with a different coolant.
Your Škoda Service Partner can also suppl y 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 th is, result in major engine damage.
Inspecting the coolant level
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 173.
– Check the level of coolant in the coolant expansion bottle ⇒fig. 149.
The coolant level when the engine is cold must lie between the “MIN”
and “MAX” markings. The level may also rise slightly above 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 in the instrument cluster ⇒page 24. We nevertheless recommend inspecting 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.
