which will lower the coolant level in
the surge tank. Continue to fill the
surge tank until the coolant level
remains approximately 1/2 in. (13
mm) above the "MIN" line. This
may take up to 2 minutes,
depending on the outside
temperature.
9.
Maintain a low idle until the
thermostat opens and the
operating temperature stabilizes. A
sign that the thermostat has
opened is when the upper coolant
pipe gets hot on the bottom side
indicating hot coolant is now
running through it.
10.
Add coolant to the surge tank until
the coolant remains 1/2 in. (13 mm)
above the "MIN" level.
11.
Operate the engine at high idle for
10 minutes. Afterward, add coolant
to the surge tank until the coolant
remains 1/2 in. (13 mm) above the
"COLD FULL" line.
12.
Reinstall the surge tank fill cap.
Check the coolant level before and after
each trip. Add coolant as necessary.
Coolant may not immediately appear at the
correct level after the radiator has been
filled. Air may be trapped in the cooling
system, which will affect the coolant level
until the air is purged.
After servicing the cooling system,
continue monitoring it for 3-5 days. The
coolant level in the surge tank will lower
when air trapped in the cooling system is
purged. During each pre-trip inspection you
should inspect recently serviced
components of the cooling system for signs
of coolant leaks.
NOTE
If the coolant frequently needs top-
ping-up or there are any signs of cool-
ant leakage, consult a PACCAR Serv-
ice dealer.
