Mark ALL your spark plug wires!!

Or, transfer one at a time from the old cap to the new cap.

It's a real pain in the %26quot;neck%26quot; to figure out where they go after the get switched around.How to change a distributor cap and rotor on a 99 jimmy 4.3?
Easy. Use a Sharpie to mark each spark plug wire's position on the distributor. Then unplug the electrical connector at the base of the distributor and loosen the 2 cap screws. Remove the cap. Now pull off the old rotor. It should come off easily.



Install the new rotor, place the cap into position and install the 2 screws. Put the spark plug wires back in the exact same positions and you're good to go.
