The 4.0L engine has an ignition system which does not use a distributor.
REMOVAL & INSTALLATION
See Figures 1, 2 and 3
- Disconnect the negative battery cable.
- Tag all spark plug wires and distributor cap terminals with a piece of tape according to cylinder number for reference when installing the wires, then remove them from the distributor cap. Note the position of No. 1 spark plug tower.
- Unclip the distributor cap and lift it straight up and off the distributor.
- Using a screwdriver, loosen the adapter attaching screws and remove.
- Loosen the screws attaching the rotor to the distributor and remove the rotor.
- Wipe the distributor cap and rotor with a clean, damp cloth. Inspect the cap.
- Position the distributor rotor with the square and round locator pins matched to the rotor mounting plate. Tighten the screws to 24-36 inch lbs. (2-4 Nm).
- Install the adapter and tighten the attaching screws to 18-23 inch lbs. (2-3 Nm).
- Install the cap, noting the square alignment locator, then tighten the hold-down screws to 18-23 inch lbs. (2-3 Nm).
- Install the spark plug wires in firing order, starting from No. 1 tower and working in sequence around the cap. Refer to the firing order illustrations in Engine Performance & Tune-up , if necessary. Make sure the ignition wires are installed correctly and are firmly seated in the distributor cap towers.
- Connect the negative battery cable.
With the rotor and or distributor cap removed, inspect all the surfaces of the components for sign of cracking, corrosion or possible water leakage, and replace if any of these conditions are found.
Inspect the metal contact surfaces of both the rotor and distributor cap for burning, grooves or pieces of metal missing. If any of these examples exist, replace the component.
