Starter - Removal & Installation

The starter motor on some models is very difficult to see from the top of engine compartment as it is covered by the intake manifold. On these models, without removing the intake manifold, the starter motor must be removed from underneath the vehicle. Because the starter motor mounting bolts are not easy to access, a long extension with a universal joint mounted on a proper sized socket could be used. A three foot transmission extension is commercially available from tool vendors that has a 3 / 8 inch drive of the driven end and 1 / 2 inch drive on the drive end. If used with a non-binding impact universal joint and a proper fitting impact socket, the starter motor fasteners can be removed from underneath the vehicle.
Once the starter motor fasteners are removed, the starter motor may have to be moved side-to-side several times to loosen the dowel pin if it has corroded in place.

NOTE When the battery is disconnected, the radio code, on-board computer and clock settings will be lost. The radio code should be obtained before disconnecting the battery or radio. Once the battery has been reconnected, the radio will not function unless the code is keyed in.

Automatic Transmission Models

1. Before servicing the vehicle, refer to the Precautions section.
2. Set the ignition switch to the OFF position.
3. Disconnect the negative battery cable.
4. Remove the climate control air intake duct at the rear of the engine compartment as follows:
   1. Release the grille clips at the rear and lift the grille upward from the rubber seal, then remove the seal.
   2. Remove the two self tapping Phillips screws from inside the duct to release the electrical harness housing.
   3. Press the electrical housing downward to expose and remove the two hex head self tapping screws on each side of the duct and lift the duct up and out of the engine compartment.
5. Remove the intake manifold trim and valve cover trim covers.
6. Disconnect the ignition coil electrical connectors and ground straps, label for reinstallation and place aside.
7. Remove the two fasteners that secure the fuel injection electrical connector harness to the rail. Remove the harness and carefully place aside toward the back of the engine compartment behind the right side strut tower.
8. Remove the intake manifold.
9. Remove the electrical leads from the starter motor and place aside.
10. Remove the starter motor mounting fasteners at the transmission bell housing, then remove the two mounting nuts at the L-shaped mounting bracket.
11. Loosen the L-shaped bracket to engine block mounting bolt slightly, then remove the bolt while supporting the starter motor.
12. Remove the bracket, then lift the starter motor upward away from the engine.
13. Visually inspect the starter pinion and ring gears for any signs of damage.
14. Installation is in reverse order of removal.

Manual Transmission Models

1. Before servicing the vehicle, refer to the Precautions section.
2. Set the ignition switch to the OFF position.
3. Disconnect the negative battery cable.
4. Raise and safely support the vehicle.
5. Remove the fasteners for the reinforcement mounted between the frame rails just behind the rear lower control arm bushing brackets. Mark the bar-s direction for proper reinstallation and remove the bar.
6. Remove the fuel line cover located near the left side rear lower control arm bushing bracket.
7. Release the fuel lines and reverse light wiring from their routing brackets.
8. Note the routing of the starter motor electrical wires, remove the wire mounting nuts, and place the wires aside.
9. Remove the top and bottom starter motor to engine-transmission mounting fasteners.
10. Remove the two mounting nuts at the L-shaped mounting bracket.
11. Loosen the L-shaped bracket to engine block mounting bolt slightly, then remove the bolt while supporting the starter motor.
12. Remove the bracket and carefully lower the starter motor downward away from the engine.
13. Visually inspect the starter pinion and ring gears for any signs of damage.
14. Installation is in reverse order of removal.
