Heater Hose Connection Revisions —
Beginning second quarter of 2004, a cooling
system revision was phased into production that
affects the ASET™ AC engine to move the cab
heater and optional fuel heater coolant return
hose connection point. This change relocates the
heater coolant return hoses from the thermostat
housing bypass area to a new location on the
radiator lower tube.
