Adding coolant
WARNINg
Do not spill coolant on the vehicle's exterior surfaces as it can damage the paint work.
If you do, wash it off immediately.
Refer to Specifications in chapter 8 for engine coolant specifications and water-to-
coolant ratio.
1. Mix a solution of Holden coolant and clean fresh water in a container as per the
ratio specified.
Note Failure to use the coolant or maintain the specified concentration may result
in voiding the New Vehicle Warranty.
2. Pour the fluid into the coolant dipstick tube (the same opening that the coolant
dipstick is stored in). Again check the level with the dipstick and add further fluid if
necessary.
3. When the level is correct, replace the dipstick and turn the cap one-eighth of a turn
clockwise to secure.
Note Only replace the dipstick one way. The word DEXCOOL on the cap should be
able to 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 (as soon as possible) from the nearest
Holden Dealer.
Note If the coolant requires regular topping up, it could indicate that there is a leak
or a fault. Contact your Holden Dealer as soon as possible.
How the engine coolant works
The specified coolant works in three ways:
•
It contains special corrosion inhibitors.
•
It helps the cooling system in hot weather by increasing the boiling point.
•
It 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.
Refer to Engine overheating in chapter 6 if the engine overheats or loses a lot
of coolant.
