17-4 COOLING - COOLING SYSTEM

ON-VEHICLE INSPECTION

1 . If the coolant decreases quickly, check whether there is any leakage in the
cooling system:
(a) Switch off the ignition.
(b) Open the engine hood.

(c) Unscrew the coolant filler cap.
CAUTION

Do not open the coolant filler cap when the
vehicle is hot. It can only be opened when the
engine cools down to the ambient temperature.

Otherwise the hot coolant or steam may lead to
personal injury.

(d) Install a testing tool on the opening of the
coolant reservoir and pressurize the cooling
system.
(e) Observe the pressure measurement. If the
pressure remains stable over time, it means
the system is properly sealed. If the pressure
drops quickly, it means the system is poorly
sealed, with possible leakage. It is necessary
to carefully check all parts of the cooling
system.

2 . Check the electronic fan:
(a) Switch off the ignition.
(b) Open the engine hood.
