Maintenance Instructions
Coolant and Optional Coolant Filter
The cooling system in vehicles with MaxxForce® 11, 13 and 15
engines, is filled at the factory with Nitrite-free Shell Rotella®
Ultra ELC (Yellow) coolant.
International Truck recommends
using only the approved coolant with the 2010 cooling packages,
and will not warrant these cooling systems that have not utilized
the recommended coolant.
The label on the deaeration tank provides additional
coolant/antifreeze information. Consult the Engine Operation
and Maintenance Manual for coolant service life details.
Some engines are ordered with an optional coolant filter that
should be replaced periodically.
For Ultra ELC equipped vehicles use only water filters without
Supplemental Coolant Additives (SCA’s) as SCA’s are not
necessary with Ultra ELC. Any time a silicone gasket/seal
exposed to the coolant is replaced while using Ultra ELC, a
fresh charge of silicates must be added to the coolant to protect
the new gasket/seal.
International® truck recommends Ultra ELC due to its ease of
maintenance and lower long-term cost of operation. Any system
using or contaminated with more than 10% conventional coolant
must be maintained like conventional coolant and receive regular
tests for Supplemental Coolant Additive (SCA) levels.
Coolant Concentration Freeze Point
Cooling systems should be checked twice a year to assure
proper coolant water concentrations.
A 53/47 coolant/water
mixture from the factory provides freeze protection down to
minus -40° F (-40° C) as well as excellent corrosion protection.
A 50/50 mixture can be easily created in the shop using
undiluted coolant and water and will provide freeze protection
down to -34° F (-36.7° C) if no further dilution is experienced
during installation.
Concentrations greater than 67% are not recommended. The
use of Shell Rotella® Ultra ELC pre-mixed to make up for coolant
loss will assure the glycol/water concentrations stay in balance.
CAUTION
Always use Shell Rotella® Ultra ELC to top-off
ELC-equipped cooling systems. Failure to do so
may result in the loss of extended life properties
and will require periodic testing for SCA levels.
Should top-off occur with conventional coolant(s)
exceeding 10% of the total cooling system
capacity, either drain and refill with Shell Rotella®
Ultra ELC or maintain as a conventional coolant
system using SCA’s at the recommended levels.
Antifreeze
For cooling system capacities, coolant part numbers, and
other information refer to SECTION 8 — MAINTENANCE
INTERVALS AND SPECIFICATIONS of this manual.
Fan Clutch
Inspect for proper operation, secure electrical connections, and
air supply as appropriate. See the Service Manual for details.
