a worn sparkplug can cost you big-time
avoid these expensive repairs by
replacing them every 30,000 miles turn
off the engine and let it cool before
getting the work pull the hood release
lever located under the dashboard at the
front of the car reach under the hood
squeeze the latch to open located in a
row along the engine and attach two
thick wires the plugs are screwed
directly into the engine one per
cylinder look for the indentation along
the engines tuff each wire connects a
specific plug to a specific wire so
always change the spark plugs one by one
as follows pull the l-shaped rubber boot
that is attached to the plug wire to
uncover the spark plugs terminal wipe
off any dirt from around the plug fit a
ratchet wrench to the socket fitting it
squarely over the head of the spark plug
you may need an extension for your
ratchet if the spark plugs are deep set
or hard to reach a ratchet with a
flexible head can come especially in
handy work close to the core as yanking
from higher can damage the spark plug
and cause it to separate turn
counterclockwise to loosen then pull the
plug out of the engine block decide
whether or not to replace the spark plug
a healthy tip looks gray as your tan
heavy deposits or a black appearance
signal and engine problem any signs of
physical damage to the electrode or core
nose also means the spark plug needs to
be replaced but first you need to gap
the new spark plug refer to your car’s
repair manual for gap size information
insert the spark plug gapping tool in
the gap between the metal center
electrode and the metal side electrode
of the plugs tip look at the tools ruled
edge to read the measurement if the gap
is too large
tap down on one side of the electrode
with a tool to widen it if it’s too
small
bend the side electrode up slightly with
the gapping tool repeat for each plug
and tighten the new spark plugs into
place
complete the process using the socket
and ratchet wrench under tightening the
plugs may lead to engine damage and over
tightening them can strip the threads on
both the plugs and the cylinders get the
plug snug without locking them replace
the spark plug wire firmly start the
ignition and listen if it sounds rough
turn it off let it cool and double check
that the wires are well pushed onto the
new plugs otherwise you’re finished
