COOLING SYSTEM
RADIATOR
Removal
1. Drain coolant from radiator and engine. Be pre-
pared to catch approximately 200 gallons (757
liters) of coolant. If the coolant is to be reused, it
must be stored in clean containers.
2. If radiator is being removed without the removal
of the complete power module, remove grille and
hood according to “Removal” instructions in Sec-
tion “B”.
Federal regulations prohibit venting air condition-
ing system refrigerants into the atmosphere. An
approved recovery/recycle station must be used
to remove the refrigerant from the air conditioning
system.
3. Refer to instructions in Section “M” and discharge
the refrigerant from the system with a recovery/re-
cycle station. The system is charged with HFC-
134A refrigerant.
a. Remove refrigerant hose clamps and remove
the receiver/drier (7, Figure 3-1) mounted on
rear, left side of the radiator shroud. Discon-
nect wiring from low pressure switch.
b. Remove clamp and disconnect inlet and outlet
hoses (4 & 5, Figure 3-2) at the condenser.
Remove mounting capscrews (3) and remove
condenser.
c. Cap all hoses to prevent contamination. Re-
move any remaining clamps attaching hoses
and wiring to radiator shroud and reposition to
allow removal of the radiator and shroud as-
sembly.
