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.

and anti-freeze approved for the

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.
Note
If the engine operates without
coolant, your vehicle may be
seriously damaged. In this case, the
repairs will not be covered by
warranty.
Engine Overheating without
Steam
If you note the overheating advise
and there are no signs of steam, the
problem may not be that serious.
The engine may overheat when:
.
The vehicle is driven in abrupt
climb at high ambient
temperatures.
.
The vehicle is stopped after
driving at high speeds.
.
The vehicle has to be driven with
the engine operating at idle
speed for a long time.
If the overheating warning remains
and still no steam is visible, observe
the following procedure for
approximately 1 minute:
1. Switch off the air conditioning
system (if equipped)
2. Try to keep the engine running
(use a gear in which the engine
rotates slowly).
If the warning of overheating
disappears, you can continue
driving. For safety reasons, drive
slowly for approximately 10 minutes.
If the temperature gauge indicator
drops to normal position, continue
driving.
If the coolant temperature does not
drop, turn off the engine and park
the vehicle immediately.
If no steam is visible, switch on the
engine at idle speed for
approximately 2 or 3 minutes with
the vehicle stopped and observe if
the overheating warning lights
go off.
If the overheating warning still
appears, switch off the engine, ask
the passengers to leave the vehicle
and wait for it to cool down. Look for
technical assistance immediately.
