Cooling System Leakage Check; Checking Expansion Tank Cap - MV Agusta Brutale 675 Workshop Manual

COOLING SYSTEM LEAKAGE CHECK

Before removing the radiator and discharging the
engine coolant, check that the cooling system does not
have leakages.
Remove the fuel tank, the seat and the underseat pan-
els (see chap. C "Upper structures").
Remove the water radiator cap and connect the tester
(of the type shown in the diagram) to the filler hole.
Do not open the radiator cap whilst 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, wrap a cloth around the filler hole to
avoid spurts of engine coolant.
Do not exceed the recommended pressure
to avoid damaging the radiator.
