256 Vehicle Care
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, this should be
done at the dealer.

Engine Air Cleaner/Filter

To replace the engine air filter,
release the clamp and remove the
air cleaner outlet duct. Disconnect
the air sensor, unscrew the 3 screws
and remove the filter housing.
To inspect the air cleaner, remove
the element from the air filter
housing and lightly shake it to
release loose dust and dirt.

Engine Coolant

Cooling Liquid Change
The engine cooling system is filled
with a long-life additive (ethylene
glycol), whose properties provide a
proper protection against freezing,
boiling and corrosion.
Coolant Level
Caution
A low coolant level can cause
engine damage.
If the cooling system is cold, the
coolant level should be about
2,5 cm above the filling line mark.
Top up if the level is low.
Fill with a mixture of distilled water
and anti-freeze approved for the
vehicle. Install the cap tightly. Have
the antifreeze concentration
checked and have the cause of the
coolant loss repaired by a Chevrolet
dealer.
{
Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.

Engine Overheating

The coolant temperature indicator
message is displayed in the
instrument panel. This message
indicates the engine temperature
increasing.
