Spark Plugs

The spark plugs in your vehicle are a special platinum-tipped design for
longer life. They only need to be
replaced every 7 years or 105,000
miles (168,000 km), whichever
comes first.
Replacement

1. Remove the four nuts, then remove the plug wire cover.
2. Clean up any dirt and oil around the spark plug caps. 3. Remove the spark plug cap by
pulling it straight out.
4. Remove the spark plug with a five-eighths inch (16 mm) spark
plug socket.

5. Put the new spark plug into the socket; then screw it into the hole.
Screw it in by hand so you do not

crossthread it.
6. Torque the spark plug. (If you do
not have a torque wrench, tighten
the spark plug two-thirds of a turn
after it contacts the cylinder head.)
Tightening torque:

Tighten the spark plugs carefully. A
spark plug that is too loose can
overheat and damage the engine. Overtightening can cause damage to
the threads in the cylinder head.

7. Install the spark plug cap.
8. Repeat this procedure for the other three spark plugs.
Reinstall the plug wire cover and
tighten the four nuts.
