CAUTION:If the malfunction indicator lamp is turned on after installing the distributor, and a DTC P1345 is found, the distributor has been installed incorrectly.
1. Position No. 1 cylinder to Top Dead Center (TDC) of the compression stroke.
2. Align white paint mark on the bottom stem of the distributor, and the pre-drilled indent hole in the bottom of the gear (3 in illustration). See Fig. 9.
3. With the gear in this position, the rotor segment should be positioned as shown (2 in illustration). See Fig. 9. The alignment will not be exact. If the driven gear is installed incorrectly, the dimple will be approximately 180 degrees opposite the rotor segment when it is installed in the distributor.
The OBD II ignition system distributor driven gear and rotor can be installed in multiple positions. In order to avoid mistakes, make sure to mark the distributor in the following positions:
The distributor driven gear.
The distributor shaft.
The rotor holes for the same mounting position upon reassembly.
Installing the driven gear 180 degrees out of alignment, or locating the rotor in the wrong holes, will cause a no-start condition. Premature engine wear or damage may result.
4. Using a long screw driver, align the oil pump drive shaft to the drive tab of the distributor.
5. Guide the distributor into the engine. Ensure the spark plug towers are perpendicular to the centerline of the engine.
6. Once the distributor is properly seated, the rotor segment should be aligned with the pointer cast into the distributor base. The pointer must have an "8" cast onto it (a "6" indicates a V6 engine component). See Fig. 10. If the segment does not come within a few degrees of the pointer, the gear mesh between the distributor and the camshaft may be off a tooth or more. If this is the case, repeat the procedure again in order to achieve proper alignment.
7. Install the distributor mounting clamp. Tighten the distributor clamp bolt to 18 ft. Lbs. (25 N.M). Install the distributor cap.
8. Install the New distributor cap screws. Tighten the screws to 21 INCH lbs. (2.4 N.M). See Fig. 8.
9. Install the electrical connector to the distributor. Install the spark plug wires to the distributor.
