CONNECT THE "BOOST" BLOWER TO THE BLEED PORTS
Once the hoses are flattened and the negative pressure has

stabilised at less than -0.7 bar, use the boost blower starting
from the bleed port closest to the expansion tank going to
the one furthest away.

Connect the boost blower and its bleed extension hose
>
to the female connector on the front of the equipment.
Use this device only, because the blower's pressure
is regulated. To begin with, remove the cap from the
bleed port located between the engine block and the
fan motor unit.
Inject air into the cooling circuit in 2- to 3-second bursts
>
in order to inject the coolant into the expansion tank.
Wait for the pressure to fall below -0.7 bar before giving
another burst.
Lhe coolant starts to be sucked out; you can check the
>
level by means of the gauge on the equipment.
Connect the blower to the bleed port.
>
Tip to help bleed the coolant : if the vehicle
has an expansion tank return, disconnect it
to create a suction effect, then block the hole
in the tank. Let the negative pressure rise
back and block the expansion tank return
hole. The coolant is sucked out. Repeat the
operation if necessary.
