Cooling System - Paccar PX-9 Operator's Manual

NOTE
If the type/oil capacity of each lubri-
cating oil pan is not known:
• Contact a PACCAR®
Authorized Repair Location.
• Determine the capacity of
the oil pan option for the
engine being serviced by using
QuickServe™ Online and the
engine serial number.
• Fill the lubricating oil pan to
the smallest oil pan capacity
listed for the engine being
serviced. Then add 1 qt (0.95
liters) of oil at a time until it
reaches the high mark on the
dipstick. Record the number
of liters/quarts added, so the
capacity is known the next
time the oil is drained.
