  Q: How to install a new distributor cap and rotor?

  A: It's common practice to install a new distributor cap and rotor whenever new Spark Plug Wires are installed. Although the breakerless distributor used on these vehicles requires much less maintenance than a conventional distributor, periodic inspections should be performed at the intervals specified in the routine maintenance schedule and whenever any work is performed on the distributor. Disconnect the ignition coil wire from the coil, then unsnap the spring clips or loosen the screws that hold the cap to the distributor body. Release the two spring clips, then remove the distributor cap-the distributor cap will only fit on the distributor body one way, so make sure the new cap is in the same position as the old one when transferring the wires. Detach the distributor cap and wires. Place the cap, with the spark plug and coil wires still attached, out of the way. Use a length of wire or rope to secure it, if necessary. The rotor is now visible on the end of the distributor shaft. Check it carefully for cracks and carbon tracks. Make sure the center terminal spring tension is adequate (not all models) and look for corrosion and wear on the rotor tip. If in doubt about its condition, replace it with a new one. If replacement is required, detach the rotor from the shaft and install a new one. While the distributor cap is off, check the air gap. Check the distributor cap for carbon tracks, cracks and other damage. Closely examine the terminals on the inside of the cap for excessive corrosion and damage. Slight deposits are normal. Again, if in doubt about the condition of the cap, replace it with a new one. When replacing the cap, simply transfer the spark plug and coil wires, one at a time, from the old cap to the new cap. Be very careful not to mix up the wires! Reattach the cap to the distributor, then tighten the screws or reposition the spring clips to hold it in place.
