Charge Air Cooler and Radiator Core Inspection and
Cleaning
Inspection and Cleaning
With the engine off, visually inspect the charge air cooler core
and radiator core assembly for debris and clogging of external
fins. Prior to engine operation, remove any debris blocking the
core.
The cores may be cleaned by externally backflushing them
with compressed air and / or water. Use high-pressure air or
water Thexton radiator cleaning wand with 90-degree tip P/N
4106-NAV, available from your International dealer, for best
results.
Cooling System
Coolant Level Check
WARNING
To prevent property damage, personal injury, and
/ or death, and to prevent hot coolant or steam,
use only the following procedure to remove the
pressure cap from the radiator or expansion
tank. Allow the engine to cool first. Wrap a thick,
heavy cloth around the cap. Unscrew the cap
slowly to allow pressure to release from under
the cap. After the pressure has been released,
the pressure cap may be removed.
WARNING
To prevent property damage, personal injury, and
/ or death, do not exceed the pressure rating on
the deaeration tank cap. Ensure that the pressure
rating of the deaeration tank cap matches that
listed on the side of the tank, or the tank may
burst.
CAUTION
To prevent property damage, if the coolant should
get extremely low and the engine very hot, let the
engine cool for approximately 15 minutes before
adding coolant; then, with the engine running,
add coolant slowly. Adding cold coolant to a hot
engine may crack the cylinder head or crankcase.
Never use water alone.
Filling Instructions
NOTE: If system has been drained, fill with fresh 50/50
diluted concentrate coolant or 50/50 pre-mixed coolant.
If the system has been flushed with water, a significant
amount of the freshwater flush will remain in the system. In
this case, refilling with a mixture with a higher percentage
(75%) of coolant concentrate is advised in order to achieve
a final mixture close to 50/50.
For vehicles with MaxxForce
®
and Navistar
