Cooling System Refill Capacities
Cooling system capacities vary greatly due to variations in bus
length, number of heaters and engine model. Total capacity may
range from 9 - 15 gallons.
• For vehicles equipped with Navistar
®
N9 or N10 engines,
fill with a 50/50 mixture of Shell Rotella ® Extended Life
Coolant (ELC) (RED) concentrate and demineralized
or distilled water, Shell Rotella
® ELC 50/50 Premix
(RED), Fleetrite ® NOAT ELC (RED) concentrate and
demineralized or distilled water, or Fleetrite ® NOAT ELC
50/50 Premix (RED).
• For vehicles equipped with Cummins ® B6.7 engines,
fill with a 50/50 mixture of Shell Rotella ® Extended Life
Coolant (ELC) (RED) concentrate and demineralized or
distilled water, or Shell Rotella
® ELC 50/50 Premix (RED).
If the system has been flushed with water or cleaner, a significant
amount of the rinse water will remain in the system. In this
case refilling with a mixture with a higher percentage (60 to
66%) of coolant concentrate is advised in order to achieve
a final mixture closer to 50/50.
Fill the system and run the
vehicle until the thermostat opens. Before adding any fluid,
check the coolant concentration and add additional water or
concentrated undiluted coolant to adjust the concentration. Run
the vehicle and retest for coolant volume level (set to MAX line)
and concentration level.
