Removal & Installation



3.7L & 4.7L Engines
  1. Disconnect the negative battery cable.
  2.  
  3. Raise and safely support the vehicle.
  4.  
  5. If equipped with 4WD, remove the front driveshaft.
  6.  
  7. Note: If equipped with 4WD and certain transmissions, a support bracket is used between front axle and side of transmission. Remove 2 support bracket bolts at transmission. Pry support bracket slightly to gain access to lower starter mounting bolt.
  8.  
  9. Remove the two mounting bolts.
  10.  
  11. Move the starter towards front of vehicle far enough for nose of starter pinion housing to clear the housing. Always support the starter during this process, do not let it hang from the wiring harness.
  12.  
  13. Tilt the nose downwards and lower the starter far enough to access and remove the nut that secures the positive battery cable wiring harness connector eyelet to the solenoid battery terminal stud. Do not let starter hang from the wiring harness.
  14.  
  15. Remove the positive battery cable wire harness connector eyelet from the solenoid battery terminal stud.
  16.  
  17. Disconnect the positive battery cable wire harness connector from solenoid terminal connector receptacle.
  18.

Testing & Troubleshooting



Correct starter motor operation can be confirmed by performing the following free running bench test. This test can only be performed with starter motor removed from vehicle. Refer to Specifications for starter motor specifications.

  1. Remove starter motor from vehicle. Refer to Starter Motor Removal and Installation.
  2.  
  3. Mount starter motor securely in a soft-jawed bench vise. The vise jaws should be clamped on the mounting flange of starter motor. Never clamp on starter motor by field frame.
  4.  
  5. Connect a suitable volt-ampere tester and a 12-volt battery to starter motor in series, and set ammeter to 100 ampere scale. See instructions provided by manufacturer of volt-ampere tester being used.
  6.  
  7. Install jumper wire from solenoid terminal to solenoid battery terminal. The starter motor should operate. If starter motor fails to operate, replace faulty starter motor assembly.
  8.  
  9. Adjust carbon pile load of tester to obtain free running test voltage. Refer to Specifications for starter motor free running test voltage specifications.
  10.  
  11. Note reading on ammeter and compare reading to free running test maximum amperage draw. Refer to Specifications for starter motor free running test maximum amperage draw specifications.
  12.  
  13. If ammeter reading exceeds maximum amperage draw specification, replace faulty starter motor assembly.
