Renault Clio 2003 Owner's Manual page 144

OPERATING FAULTS
On the open road
• Steering becomes hard (more effort
required to turn steering wheel).
• The engine overheats. The coolant
temperature warning light comes on
(or the gauge needle moves into the
red zone).
Radiator: never fill a hot radiator with cold coolant if a considerable quantity has been lost. After any operation
on the car which has involved even partial draining of the cooling system, it must be refilled with a new mixture
prepared in the correct proportions. Reminder: only products approved by RENAULT's Technical Department
may be used for this purpose.

CAUSES
Belt broken.
Lack of oil in pump.
Water pump: belt stretched or broken.
Faulty engine cooling fan.
Coolant leaks.
REMEDIAL ACTION
Have the belt replaced.
Top up the oil (see maintenance
section).
If the problem persists, consult a
RENAULT Dealer.
Stop the car and switch off the engine.
Consult a RENAULT Dealer.
Check the condition of hoses and
clips.
Check the expansion bottle: it should
contain coolant. If it does not, top it
up (after letting it cool down). Take
care not to scald yourself. This action
is only temporary, consult your
RENAULT Dealer as soon as possible.
