Removal Procedure

1998 GMC Envoy 2WD V6-4.3L VIN WSECTION Removal Procedure



REMOVAL PROCEDURE

NOTICE: There are two procedures available to install the distributor.

Use Installation Procedure 1 when the crankshaft has NOT been rotated from the original position.

Use Installation Procedure 2 when any of the following components are removed:
^ The intake manifold.
^ The cylinder head.
^ The camshaft.
^ The timing chain or sprockets.
^ The complete engine.
If the Malfunction Indicator Lamp turns on, and a DTC code P1345 sets after installing the distributor, this indicates an incorrectly installed distributor.

Engine damage or distributor damage may occur. Use Procedure 2 in order to install the distributor.
1. Turn OFF the ignition switch.
2. Remove the spark plug wires from the distributor cap.
3. Remove the electrical connector from the base of the distributor.
4. Remove the two screws that hold the distributor cap to the housing.
5. Discard the screws.
6. Remove the distributor cap from the housing.
7. Use a grease pencil in order to note the position of the rotor in relation to the distributor housing. The mark is identified in the graphic with the number 1.
8. Mark the distributor housing and the intake manifold with a grease pencil.




9. Remove the mounting clamp hold down bolt.
10. Remove the distributor.




11. As the distributor is being removed from the engine, watch the rotor move in a counter-clockwise direction about 42 degrees. This will appear as slightly more than one clock position.
12. Note the position of the rotor segment.
12.1. Place a second mark on the base of the distributor.
This will aid in achieving proper rotor alignment during the distributor installation.
