1. If the type/oil capacity of the oil pan is
not known:
• Contact a Cummins® Distributor/
Dealer
• Determine the capacity of the oil
pan option for the engine being
serviced. Use QuickServe™
Online and the engine serial
number
• For the first oil drain interval, use
the 15 qt [14.2 liter] oil drain
interval. When filling the engine
with oil, determine the oil capacity
of the oil pan
Cooling System
Maintenance
Information about concentration and
condition of coolant, including filter.
The cooling system in your vehicle was
factory filled with extended life coolant that
meets or exceeds all ASTM D6210 and
Caterpillar EC-1 requirements. PACCAR
recommends only using a 50/50 mixture of
distilled water and ELC when cooling
system service is required. A 50/50 mixture
of ELC and distilled water will provide
freeze protection down to –34°F (–37°C),
which is adequate for most locations in
North America. For extremely cold
operating conditions, a 60/40 mixture
(coolant/water ratio) can be used to
provide freeze protection down to -62°F
(-52°C).
Unless otherwise optioned, factory fill
coolant is an ethylene glycol, nitrited
organic acid technology (NOAT) extended
life coolant (ELC) formulation at a 50/50
coolant-to-distilled water mixture. The
factory fill exceeds ASTM D6210 and
Caterpillar EC-1 requirements. Maintaining
coolant chemistry and freeze protection is
critical to engine and cooling system
component health and longevity.
