Distributor Assembly Replacement
Removal Procedure
NOTICE: If the distributor is removed from the engine, It can be re-installed using "procedure A" as long as the crankshaft has not rotated
from the original position. If the intake manifold, cylinder head, crankshaft, camshaft, timing gear or complete engine was removed or
replaced, "Procedure B" must be followed in order to correctly install the distributor. A DTC code may also indicate an incorrectly installed
distributor and engine or distributor damage may occur. Procedure B must then be used.
1. Turn OFF the ignition switch.
2. Remove the spark plug and the ignition coil wires from distributor cap.
3. Remove the three-wire hall effect switch connector from the base of the distributor.
4. Remove the two screws holding the distributor cap to the housing.
5. Remove the distributor cap.
A. Use a grease pencil in order to note the position of the rotor in relation to the distributor housing. Identify the mark with the number 1.
B. Mark the distributor housing and the intake manifold with a grease pencil for proper alignment when reinstalling.
6. Remove the mounting clamp hold down bolt.
7. Remove the distributor.
8. As the distributor is being removed from the engine, you will notice the rotor move in a counter-clockwise direction about 42 degrees. This will
appear as slightly more than one clock position. Noting the position of the rotor segment by placing a second mark on the base of the distributor
will aid in achieving proper rotor alignment during the distributor installation. Identify the second mark on the distributor housing at number 2.
Installation Procedure A
1. Remove the new distributor cap.
