Special tooling required Mot. 1732 Tool for removing and re?tting the alternator pulley Tightening torquesm the alternator decou- pling pulley I – PARTS AND CONSUMABLES FOR THE REPAIRS Parts always to be replaced: – the alternator belt, – the tensioning roller, – the mechanic tension wheel mounting bolts. II – PRECAUTIONS DURING REPAIR It is essential to replace an alternator decoupling pulley with a decoupling pulley. III – EQUIPMENT REQUIRED – Torque wrench capable of tightening a left-hand thread. IV – REMOVAL Remove the vehicle alternator (see 16A, Starting – charging, Alternator 110276 110268 Position adapter (2) from the tool kit (Mot. 1732) (corresponding to the alternator rotor recess) in the hexagon socket (1). 110267 Position the hexagon socket (1) from the tool box (Mot. 1732) in the alternator pulley. 110269 Position the adapter holder (3) in socket (2). 110270 Hold the hexagon socket (1) using an open-jawed spanner (4). Loosen the decoupling pulley (5) using a ratchet, (6) (turning it in the clockwise direction.). Remove the decoupling pulley. V – REFITTING Position: – the hexagon socket in the alternator (1), – the adapter (2) (corresponding to the alternator ro- tor mark), – the adapter holder (3) on the adapter(2). Note: Check that the torque wrench is capable of tigh- tening in an anticlockwise direction. 110266 Screw the new decoupling pulley onto the alternator rotor. Tighten to torque the alternator decoupling pulley (80 Nm) using a torque wrench(7). Refit the vehicle alternator (see 16A, Starting – charging, Alternator).

CHRYSLER ALTERNATOR See Figures 1, 2, 3, 4 and 5 Fig. 1: Alternator mounting-2.2L and 2.5L engines Fig. 2: Disconnecting alternator wiring-2.2L and 2.5L engines Fig. 3: Disconnecting alternator wiring Fig. 4: Removing the pivot bolt and nut Fig. 5: Removing the alternator from the vehicle Disconnect the negative battery cable. Label and disconnect the wiring (for easy installation). Remove the air conditioning compressor drive belt, if equipped. Loosen the alternator adjusting bracket bolt and adjusting bolt. Remove the alternator belt. 5. Remove the bracket and mounting bolts. 6. Remove the pivot bolt and nut. 7. Lift the alternator from the vehicle. When lifting the alternator out of the vehicle on some years with A/C, clearance may be restricted by the condenser cooling fan assembly or the A/C compressor and mounting bracket assembly, if so, removal of one of these items will be necessary. 8. Position the alternator against the engine. 9. Install the pivot bolt and nut. 10. Install the mounting bracket bolts, and adjusting bolt. 11. Install drive belts and adjust to specification. 12. Tighten all the mounting bolts and nuts. 13. Connect all alternator terminals. 14. Connect the negative battery cable. Disconnect the negative battery cable. Disconnect the wiring and label for easy installation. Remove the air conditioning compressor drive belt. Loosen the alternator adjusting bracket locknut and adjusting screw. Remove the alternator belt. 5. Remove the bracket locknut and mounting bolt. 6. Remove the pivot bolt and nut. 7. Remove the alternator from the engine. 8. Position the alternator against the engine. 9. Install pivot bolt and nut. 10. Set the mounting bracket in place and install the bracket mounting bolt and locknut. 11. Install the drive belts and adjust to specification. 12. Tighten all the mounting bolts and nuts. 13. Connect all alternator terminals. 14. Connect the negative battery cable.

1. Use a scan tool to monitor the fuel trim numbers and the Mass Air Flow (MAF) sensor data stream grams/sec readings. Nominal
values are 5 grams/sec at idle in Park, and >150 at Wide Open Throttle (WOT) and 5000 RPM, in gear. Some scan tools have a freeze frame feature, which is useful in trouble shooting if the problem is set at idle versus at cruise. Vacuum leaks and crankcase breather problems generally show up at idle. Voltage at the airflow meter should be .7-.9V at idle and increase from there with more airflow. 2. Monitor the crankcase vacuum with a vacuum gauge, which can be adapted onto the tube for the oil dipstick. Specification for the crank case vacuum is 8 to 15 millibar, this equals about 1/4 to 1/2 PSI or pounds per square. So, 1 PSI of vacuum would be twice as much as there should be at idle. The proper method, per BMW, is to use a slack tube manometer which can be made easily with clear tubing and making it into a U shape and have it marked in inch increments then half fill it with water. When crankcase vacuum is applied to one side of the tubing it should displace 4 to 6 inches of water if the crankcase breather is working correctly. 3. Monitor the fuel pressure. It should be a constant 50 – 53 PSI.

Switch off ignition. Follow instructions for disconnecting and connecting battery. See: Battery/Service and Repair Disconnect and cover battery negative lead. WARNING: Danger of scalding! Only perform these tasks on an engine that has cooled down. Remove alternator drive belt. Remove fan cowl. Drain coolant. Release bolts (1) on alternator. Release nut (1). Disconnect battery positive lead (2) from alternator. Disconnect plug (3). Release screw (4) and remove roller. Release screws (5) on alternator. Recycling A residual quantity of coolant emerges when the alternator is removed from the housing. Catch and dispose of escaping coolant. Observe country-specific waste-disposal regulations.
