REMOVAL (1) Remove air cleaner duct or air cleaner assem- bly. (2) Remove battery. PCM. (5) Remove PCM. INSTALLATION (1) Connect 60-Way electrical connector to PCM (Fig. 1). (2) Install PCM. Tighten mounting screws. COOLANT TEMPERATURE SENSOR On 2.2L TBI, 2.5L TBI and 2.5L MPI (flexible fuel AA-Body) engines, the coolant temperature sensor is REMOVAL (1) Drain cooling system until coolant level is below coolant sensor. Refer to Group 7, Cooling System. (2) Disconnect electrical connector from sensor. INSTALLATION (1) Install coolant sensor. Tighten 2.2L TBI, 2.5L TBI or 2.5L MPI engine coolant sensor to 28 N Im (20 ft. lbs.) torque. Tighten the 3.0L engine coolant sensor Im (60 in. lbs.) torque. (2) Connect electrical connector to sensor. System. IGNITION COIL—2.2L TBI, 2.5L TBI AND 2.5L MPI The ignition coil mounts to the thermostat housing (Fig. 4).
