SteP 1 :
Remove
the
original
radiator
cap
after
assuring
that
the
cooling
system
is
depressurized
and
cool,
.
Step 2:
Choose
the
correct radiator
cap
for
the
vehicle
being
tested
from
the
t€st
kit
and
install
on
cooling
system
opening.
.
Step
3: Remove
the
hand
pump
assembly
from
the
test
kit
and fasten
the
quick
coupler
at
the
end of
the hose
to the
radiator
cap securety.
Operate the
hand
pump
until
reaching
the
pressure
recommended
by the
vehiele
manufacturer.
(See
fig.
1
& 2) DO
Nor
exceed
vehicle
manufacturer's
recommended
pressure
or maximum
gauge
range
pressure
of
35psi (2.Sbar).
.
step
4:
Check
the
pressure
reading
on
the
gauge
immediately
after
reaching
the vehicle
manufacturer's
recommended
pressure.
lf
the
pressure
reading
drops,
there is
a
leak
in
the
cooling
system.
After
pressure
testing
is
completed,
press
the release
button
on
the
quick
coupler
until
the
reading
on the
gauge
reads
0. Remove
quick
coupler
from radiator
cap
and
then remove
radiator
cap
from
the
cooling
system
opening.

fasten
the
quick
coupler
at
the
end
of the
hose
to
the

hand
pump
until
reaching
the
pressure
recommended
by the
vehicle
manufacturer.

Do
not
exceed
vehicte
manufacturer,s
recommended
pressure

(2.5bar).
.
step
3:
check
the
pressure
reading
on
the
gauge
immediatety
after
reaching
the vehicle
manufacturer's
recommended
pressure.
lf
the
pressure
drops,
there
is
a feak
in
the
radiator
cap.
After
pressure
testing
is
completed'
press
the
refease
button
on
the
quick
coupler
until
the
reading
on
the
gauge
reads
0. Remove
quick
coupler
from
radiator
cap
and
then
remove
the original
radiator
cap from
the
radiator
cap
connector.
Discard
original
radiator
cap

Purge
Gooling
System
.
Step 1: Drain
coolant from
radiator
as
well
as
possible.
.
Step 2: Remove
the
purge
and
refill tool from
the test kit
and
hang the
tool
in
a convenient
location
under
the hood with the hook
provided.
.
Step 3: Choose
the
correct radiator
cap for the vehicle
being tested,
or
the
universal rubber
radiator
adapter
from the test
kit
and
install the one
of
your
choice
on the cooling
system
opening.
Fasten
the
quick
coupler
at the
end
of the hose
on the
purge
and refill
tool to the radiator
cap
securely.
(Seefig.4&5)
.
Step 4: Turn
valve No.
3 to the open
position
and
valve
No. 6 to
the
closed
position.
(See

.
Step 5: Connect
air
supply
to
the
purge
and refill
tool and
press
operating
button
untif the
pressure
reaches
20-25
Hg
(50-60cmHg),
