Engine Overheating - HOLDEN WN CAPRICE 2014 Owner's Handbook Manual

10-10 Vehicle Care
For engine coolant specifications
and water-to-coolant ratio, see
Recommended Fluids and
Lubricants on page 11-2. Always
use the specified ratio.
1. Mix a solution of Holden coolant
and clean fresh water.
2. Add coolant into the coolant
dipstick tube (where the dipstick
is stored).
3. Check the level on the dipstick
and add further coolant if
necessary.
4. Replace the dipstick.
5. Rotate the cap one-eighth of a
turn clockwise until secure and
the word DEXCOOL can be read
from the front of the vehicle.
In emergency situations, plain clean
fresh water may be used temporarily
until the correct Holden coolant is
obtained. Replace as soon as
possible from the nearest Holden
Dealer.
If the coolant requires regular
topping up, contact a Holden
Dealer.
How the engine coolant works
The coolant contains special
corrosion inhibitors.
Coolant helps the cooling
system in hot weather by
increasing the boiling point.
Coolant protects against freezing
down to 37 °C, provided the
specified concentration is
maintained.
Warning
Corrosion inhibitors and
antifreeze fluids are poisonous.
Use extreme care when handling.
If swallowed, seek medical
attention. Do not remove the
coolant reservoir cap if the engine
and radiator are still hot. Scalding
fluid and steam can be blown out
under pressure which could
cause serious burns.
If the engine overheats or loses
coolant, see Engine Overheating on
page 10-10.
