For more information on the Fast Idle Warm Up feature,
contact a PACCAR authorized repair location.
CAUTION: Do not operate the engine at low idle
for long periods with engine coolant tempera-
ture below the minimum specification in “
Cool-
ing System
” on page 57. This can result in the
following:
• Fuel dilution of the lubricating oil.
• Carbon build up in the cylinder.
• Cylinder head valve sticking.
• Reduced performance.
If an engine must idle for an extended period of
time, it should be done at fast idle (1,000 rpm or
greater) until the coolant temperature meets the
specification.
Cold Weather Starting
General Information
Follow the Normal Starting Procedure in this section. If
equipped with an intake air heater, the Wait-To-Start lamp
will stay on longer.
Refer to the vehicle operator's manual instructions for any
additional cold weather starting procedures.
