Cooling System - Skoda YETI - 11-2009 Owner's Manual

For the sake of the environment
•
You must on no account pour oil into the ground or into the sewage system.
•
In view of the problems involved in properly disposing of old oil, the necessary
special tools and the knowledge required for such work, we recommend that you have
the oil and oil filter change carried out by an authorised Škoda Service Partner.
Note
After your skin has come in contact with the oil, you must thoroughly wash your skin.

Cooling system

Coolant
The job of the coolant is to cool the engine.
The cooling system does not require any maintenance under normal operating condi-
tions. 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.
Using the system Safety
We recommend that you use the same coolant additive - G12 PLUS-PLUS (purple in
colour) for topping up the system.
Please contact an authorised Škoda Service Partner if you have any questions
regarding the coolant or if you wish to fill up with a different coolant.
An authorised Škoda Service Partner can also supply you with the correct coolant addi-
tives.

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 ⇒ page 203.
– Check the level of coolant in the coolant expansion bottle
If the coolant level in the reservoir is too low, this is indicated by the warning light in
the instrument cluster ⇒ page 34, "Coolant temperature/ Coolant quantity ". We
