rate until the surge tank is full (to
the base of the ll neck). It may be
necessary to pause for 1 minute
and then re-ll if the uid level
dropped.
5. Close any
drain valves that were
opened in Step 1.
6. Start the
engine and idle at low
RPM.
7. During low
rpm idle, air will purge
from the cooling system which will
lower the coolant level in the surge
tank. Continue to ll the surge
tank until the coolant level remains
approximately ½ in. above the
"MIN" line. This may take up to 2
minutes, depending on the outside
temperature.
8. Operate the
engine throttle
until the operating temperature
stabilizes (when the thermostat
opens).
9. Fill the
surge tank as necessary
to raise the coolant level to ½ in.
above the “MIN” level.
10. Operate the
engine at high idle for
another 10 minutes and then ll
the surge tank again to ½" above
the “MIN” level.
11.
Replace the surge tank ll cap.
Check the
coolant level after each trip.
Add coolant as necessary. You may
nd your coolant level is not up to the
correct level soon after you have lled
the radiator. This may be because all
the trapped air in the system has not
yet been purged. It takes a little time
for all of the air to leave the system
after you ll your radiator.
