REMOVAL AND INSTALLATION (Continued)

INSTALLATION
For installation, reverse the above procedures.
Install screws to retain heater core in housing.
Replace heater core tube inlet O-rings. Tighten
heater core tube retaining plate to 361 N´m (276
9 in. lbs.) torque.
HEATER HOSES
REMOVAL
NOTE: Review Safety Precautions and Warnings
before proceeding with this operation.
(1) Drain engine cooling system. Refer to Group 7,
Engine Cooling.
(2) Loosen clamps at each end of heater hose to be
removed (Fig. 38) and (Fig. 39).
CAUTION: When removing hoses from heater core
inlet or outlet nipples, do not use excessive force.
Heater core may become damaged and leak engine
coolant.(3) Carefully rotate hose back and forth while tug-
ging slightly away from connector nipple. If the hose
will not come off, slice the hose at the connector nip-
ple and peel off heater hose. This method will require
heater hose replacement.
