Refilling coolant
Coolant helps keep the combustion engine at
the right operating temperature. The heat
transferred from the engine to the coolant
can be used to warm the passenger compart-
ment.
When refilling coolant, follow the instructions
on the package. Never fill the cooling system
with only water. The risk of freezing is
increased with too low or too high amounts of
coolant.
If there is coolant under the vehicle, smoke
from the cooling system, or if more than
2 liters (about 2 quarts) of coolant has been
added to the system, there could be some-
thing wrong with the cooling system and star-
ting the vehicle could damage the engine. Call
a tow truck and do not attempt to start the
engine.
WARNING
The coolant may be very hot. Never
unscrew the cap when the coolant is hot. If
coolant must be filled, unscrew the expan-
sion tank cap slowly to relieve overpres-
sure.
