Start with a cool/cold engine.
Four cylinder: Remove spark plug wire boots (four in a row on top of
the engine). DO NOT PULL ON THE WIRE only the rubber top. Make sure the
wires are numbered, if not, number them. They MUST go back to the same
hole they came out of after the new plugs are installed. Remove
the spark
plugs
with a 16mm spark plug wrench. Install new plugs (any auto parts store
can tell you what your options are here): Start threading the new plugs by
hand so you don't cross thread the engine head by accident. Then
complete tightening them gently. Spark plugs are supposed to be
tightened to a specific torque: 13ftlbs in this case. If you choose to
not use a torque wrench do not overtighten the plugs. Reinstall boots
securely.
6-Cylinder: Remove engine cover, if present. Disconnect the six
connectors on each of the ignition coils. Remove each of the six
ignition coil bolts and then remove the coils by pulling straight up --
arrange them so that you know which goes back where. Remove and install
the six plugs
as described above. Reinstall the ignition coils with their bolts
(torque: 69 in-lbs), then wires. Replace the cover.
I would never answer a moron who writes "U" instead of "you."
