Cooling System - Skoda FABIA Owner's Manual

Cooling system

Coolant
The job of the coolant is to cool the engine.
The cooling system does not require any maintenance under normal operating
conditions. The coolant consists of water with a concentration of coolant additive
of 40 %. This mixture not only provides antifreeze protection 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 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.
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 factory-filled with coolant (purple in colour), which complies
with the specification TL-VW 774 G.
We recommend that you use the antifreeze agent G12 PLUS - PLUS (purple in
colour) for topping up the system.
We recommend that you contact your Škoda Service Partner if you have any ques-
tions regarding the coolant or if you wish to fill up with a different coolant.
A specialist garage can also supply you with the correct coolant additives.
Using the system Safety Driving Tips General Maintenance
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
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 185.
– Check the level of coolant in the coolant expansion bottle
The coolant level when the engine is cold must lie between the "MIN"
A A
and "MAX" markings. The level may also rise slightly above the
B A
"MAX" marking when the engine is warm.
