To replace spark plugs, locate them in the center of the valve cover(s). For V6 models, accessing the rear cylinder bank plugs may require removing the upper intake manifold. Tools needed include a spark plug socket, extensions, a gap gauge, and a torque wrench. Purchase new plugs in advance, adjust gaps, and replace them one at a time. Ensure correct plug type. Allow engine to cool completely before removal. Check new plugs for defects and gap adjustments. Use a gauge to check and adjust gap as specified on label. Remove ignition coils to access plugs, clean around plug hole with compressed air. Remove and replace each plug, applying anti-seize compound and using torque wrench or ratchet for proper tightening. Use rubber hose to thread plugs without damaging threads. Repeat for all plugs.

On these vehicles, the spark plugs are placed at the top of the engine. Usually, tools required for spark plug replacement include a ratchet-fitted spark plug socket (spark plug sockets are padded on the inside to avoid damage to new plugs' porcelain insulators), different extensions, and a gap gauge to verify and modify gaps of new plugs. The new plugs should be tightened with a torque wrench. Adjust new ones in advance and replace them one by one is suggested when replacing the spark plugs. When buying new spark plugs, make sure you get the correct type for your engine; this can be found in the factory owner's manual. Wait until the engine has cooled off entirely before attempting to remove any of its plugs; these engines have aluminum cylinder heads that can be destroyed if they are taken out while still hot. While waiting for it to cool down completely check over each of your new ones for defects and adjust their gaps accordingly: insert proper thickness gauge between electrodes at tip of plug-gauge should just slide between electrodes with slight drag-if gap is wrong use adjuster on body of gauge to bend curved side electrode slightly until proper gap obtained-only bend side electrode not center or else risk cracking or chipping surrounding porcelain insulator around center electrode-if side electrode isn't directly above center then bend it with adjuster until directly so-look carefully at insulator if cracked don't use this particular plug-only wire-type gauges should ever be used on platinum or iridium type sparkplugs as other types will scrape thin coating from electrodes thereby significantly shortening life span On V6 engines remove engine cover & intake manifold; some engines have individual ignition coils which must first be removed in order access plugs-disconnect electrical connector & pull straight up/outward from coilpack mounting bracket; on remaining motors remove one wire but do not yank cable itself out (use tool); compressed air may also blow debris away from hole around plug so nothing falls into cylinder while removing it-place socket over top of plug & remove by turning counterclockwise; use ratchet+extension to take them out; compare with pictures shown for general running condition Apply small amount of anti-seize compound to threads before installing new one-put in until no more turning can be done by hand then tighten with torque wrench or ratchet (if torquing is not possible) but remember to thread first few turns gently using short length rubber hose slipped over end of plug as tool because hose grips enough but starts slipping if plug starts cross-threading which protects against damaged threads requiring costly repairs On V6 engines check ignition coil before pushing onto end inspect when four cylinder spark plugs Repeat steps for other plugs.

Remove the spark plug wire or ignition coil, then use a spark plug socket and ratchet to remove the spark plug by turning it counterclockwise. Apply a small amount of anti-seize compound to the spark plug threads before installing the new plug.
