> Remove the battery cover.
> To begin, take the cap off the bleed hole situated between
the engine block and the engine-driven fan.
> Inject air into the cooling system, in bursts of 2 to 3
seconds, in order to part the walls of the hoses and draw
up the coolant into the expansion tank. Wait for the
pressure to go back down under -0.7 bar before giving
another burst of air.
III. Testing the safety valve on the cap
09
PLACE THE CAP ON THE TEST DEVICE ON THE MACHINE
> Check the safety valve is working properly and set at the right pressure. To do this, screw the cap onto the adapter provided,
and turn the control to the left to position "T". The valve must trigger at between 1.6 bar and 1.8 bar, pressure which can be
checked using the pressure gauge on the right.
IV. Testing the vacuum tightness circuit
10
CHECK THE TIGHTNESS OF THE SYSTEM
> Once the cooling system is empty, let the pressure stabilise at between -0.75 bar and -0.8 bar, the close the drainer valves,
check that the pressure does not go up over 0 seconds.
V. Filling the cooling system with new coolant
11
FILL THE SYSTEM

> Can be done at any time during the coolant draining and
cooling system filling procedure.
