type spark plug with the same physical dimensions as the
original equipment spark plug.

3. Check the gaskets for damage and replace if

necessary.

4. Measure the spark plug gap. The specification is 1.05

mm (0.040”).

Spark Plug Cables

Spark Plug Cables

The cable contains a synthetic conductor which is easily
damaged. Never stretch or kink the cable. Disconnect the
cable from spark plug and the ignition coil.

The original equipment cables and the ignition coil are
marked to show correct location of the cables. If spark
plug cables or the ignition coil are replaced previously,
before cables are removed from the ignition coil, mark the
cables and the coil so they can be reconnected in the
same position.

014RX050

Inspection Procedure

NOTE: Never puncture the spark plug cable’s insulation
with a needle or the pointed end of a probe into the cable.
An increase in resistance would be created which would
cause the cable to become defective.

1. If the cable has broken or cracked insulation, it must

be replaced.

2. If the terminals are corroded or loose, the cable must

be replaced.

3. Check that the cable resistance does not exceed 10 k

W

 per foot.
