3. Insert the cone adapter with vacuum gun into
the radiator filler neck (no loss tank) or
coolant aux tank; make sure the refill hose
valve is closed.
4. Turn on the air supply and Press the knob,
allow the vacuum level to reach approximately
20-25 in Hg (50-60 cm Hg) and release the
knob (The gauge reading may be slightly less
in higher elevations but a proper vacuum
should still be reached within 3 minutes). Let
the system hold for 20 seconds to observe for
a drop in vacuum.
CAUTION
A drop in the gauge reading within 20
seconds indicates a vacuum leak in the
system, which will require locating and
rectifying the leakage before proceeding
further.
NOTE
During this procedure the radiator hoses will
collapse under the vacuum being generated
- this is normal.
