Hi,
Things You'll Need: Spark plug socket and wrench
Twist
and pull the spark plug wire from the leftmost spark plug on the front
of the engine. Grasp the spark plug wire by the "boot" or the end of
the wire that cups the plug. Avoid pulling on the wire itself.
Place
the spark plug socket on the spark plug. Turn the wrench
counterclockwise to remove the spark plug. Unscrew the plug until it is
fully removed from the engine.
Install
the new spark plug by carefully placing it in the hole by hand. Turn
the spark plug clockwise, but do so only gently by hand. Ensure that
the spark plug screws in gently and naturally. Stop turning it at the
first sign of major resistance. Check to make sure that you have not
stripped the threads. Move on to the next step only when you're sure
that you've positioned the plug at the correct angle and have it
threaded most of the way in.
Position
the spark plug socket over the spark plug and tighten it with the
ratchet. Avoid tightening it too much. It will offer increased
resistance for about half a turn as the metal washer on the plug is
compressed. Once it is good and snug, stop there.
Replace the wire by handling the boot of the spark plug wire. Listen for a "click" that indicates correct installation.
Use
this procedure for the remaining two plugs on the front and the three
plugs on the back of the engine. Remove and replace one plug at a time,
to ensure that you don't mix up the wires.
Best regards.
