The coolant expansion bottle is located in the engine compart-

ment" on page 172.
– Check the level of coolant in the coolant expansion bottle
⇒ page 177, fig.
129. 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.
A drop in coolant level in the bottle to too low will be indicated by the
warning light in the instrument cluster
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. Pne should not merely top up the coolant in the reservoir. It is also
important to have the cooling system inspected without delay by a Škoda
dealer.
Losses can only occur through the pressure relief in the cap of the coolant
expansion bottle which is completely free of leaks if the coolant boils as a
result of overheating and is forced out of the cooling system.
One should contact a Skoda dealer as soon as possible if the source of
overheating itself cannot be determined and removed, since there may be
grave damage to the engine.

Replenishing the coolant
– Switch the engine off.
– Allow the engine to cool down.
– Place a cloth over the cap of the coolant expansion reservoir
⇒ page 177, fig. 129
and unscrew the cap carefully by
turning it to the left ⇒
.
– Top up the coolant.
– Screw the cap on tight.
The coolant which you use for replenishing the system, must comply with
certain specifications ⇒ page 177, "Coolant". Do not use an alternative
additive if the coolant additive G12PLUS is not available in exceptional
cases. Just top up the system with water and as soon as possible arrange
adjustment to correct the mixing ratio of water and coolant additive again
by a Škoda dealer.
Only use fresh coolant for topping up the system.
Do not fill up over the "MAX" mark! Excess coolant which is heated up is
forced out of the cooling system through the pressure relief valve in the
cap of the coolant compensation bottle.
Wait until the engine has cooled down for a system which has suffered a
major loss of coolant before pouring in coolant. This is necessary to avoid
engine damage.
Do not continue your journey if for some reason it is not possible under
the conditions prevailing to top up with coolant. Switch off the engine
and obtain professional assistance from a Škoda dealer.
