COOLING SYSTEM LEA AGE CHEC

Before removing the radiator and discharging the engi-
ne coolant, check that the cooling system does not
have leakages.
Remove the expansion tank cap and connect the
tester (of the type shown in the diagram) to the filler
hole.
Use the special tool to unscre
sion tank cap.
Do not open the cap of the expansion tank
hen the engine is hot.
Apply a pressure of approximately 120 kPa (1.2
kg/cm 2 ) and check that the system maintains the pres-
sure for at least 10 seconds.
If the pressure diminishes within ten seconds means
that there is a leak in the system.
If so, check the entire system and substitute the defec-
tive/damaged parts.
When removing the tester from the filler
hole rap a cloth around the filler hole to
avoid spurts of engine coolant.
Do not exceed the recommended pressure
to avoid damaging the radiator.

EXPANSION TAN CAP CHEC

Check the release pressure of the radiator cap by utili-
sing the appropriate tester as follows:
Apply the cap to the tester as indicated and slowly
create a pressure by activating the tester.
Ensure that the pressure increase is stopped at 110 ±
15 kPA (1.1±0.15 kg/cm 2 ) and check that with the
tester held steady, the pressure is maintained for at
least ten seconds. Substitute the cap if the pressure is
not maintained for ten seconds.
