I've written these instructions before on this site.... *sigh* let me find them... *Sourced from: http://www.answerbag.com/q_view/174096 Note that these instructions are for changing both the plugs AND wires, so ignore the irrelevant parts as you wish. -- As Darryl points out, why exactly are you changing the plugs on a 2006 model year vehicle? If there is a problem with one plug, then just change that one. There should be no reason to have to change every plug on a (basically) new vehicle. Could you provide some symptoms or the reasons you have for believing this procedure is required? -- ---- You will need many tools. I think I already answered a question like this and I could copy/paste it, but I'm too lazy to find it. Tools: -Ratchet with spark plug socket (there are two sizes of these sockets so be sure to get the correct one) -Gloves (optional yet recommended) -New plugs -Spark plug gapping tool -New wires -book with proper spark plug gap information -2 containers - one for new parts one for old parts -Masking tape Method: 1. Find proper spark plug gap in manual/online 2. Using gapping tool, gap all plugs correctly. (double-check after doing so) 3. Start engine, and remember the noise it makes. Shut off engine. Then, open the hood 4. Remove any shrouding, etc that blocks access to plugs 5. Remove ONE wire and set into old parts bin 6. Remove the exposed spark plug using ratchet and SP socket 7. Place old plug into old parts bin 8. Hand-start new spark plug into exposed hole, tightening to a stop with ratchet. Then, once it stops turning, give it a very slight extra push (a few mm extra) 9. Install new wire exactly as old one was installed. 10. Mark installed wire with a piece of tape (this is so you can tell the new ones from the old ones) 11. Repeat steps 5-10 for all additional plugs and wires. 12. When finished, double (or triple) check all connections, making sure they are correct and tight. Then remove all tape (all wires should have tape on them - if they don't then make sure you didn't forget one) 13. Replace any shrouding that was removed before install. 14. Close hood, dispose of old parts (although I suggest storing them for a bit in case the new ones have a problem) and start engine. Listen for any odd noises - it should sound exactly as it did before, or better. You're done! *Remember to take your time - a rushed job could come back to bite you. Hope this helps, Good luck

How do you take out an appendix? (SIGH)...put the patient to sleep, cut open over the appendix; take out appendix, close wound, wake patient. You're done!!

its a good idea to know the firing order of your trucks engine i've had a lot of wanna be mechanic ask me to rewire there engine because they thought they took off the right wire from the rite plug

Find the spark plugs, located in a row along one side of the engine (on an in-line 4-cylinder engine) and attached to thick wires, called spark plug wires. Cars with V-shaped engines (which can have 4, 6 or 8 cylinders) will have spark plugs and spark plug wires on both sides of the engine. Change 1 spark plug at a time, always putting the plug wire back on before changing the next spark plug. Pull off one spark plug wire where it attaches to the plug. There is a little rubber boot at the plug end of the wire; pull on this part. Pulling higher up on the wire can damage the spark plug wire and cause it to separate. Blow or wipe away any dirt or debris around the spark plug. You do not want anything to fall into the cylinder while the spark plug is out. With the spark plug socket and a ratchet, remove the spark plug by turning it in a counterclockwise direction. You may need an extension for your ratchet if the spark plugs are deep-set or not directly accessible. Ratchets with flexible heads are especially helpful for hard-to-reach spark plugs. Check the spark plug to make sure it needs replacing. A good spark plug should be lightly coated with greyish brown deposits. If heavy deposits are present, if the spark plug is black or if the electrode or core nose are damaged, the plug needs to be replaced. ***Gapping the New Spark Plugs Step 1: Find the chart listing the proper "gap" for your plugs in your car's repair manual. The spark plug gap may also be on the sticker on the inside of the car's hood. The parts store can provide you with this specification as well. Step 2: Insert the spark plug gapping tool in the gap between the metal center electrode and the metal side electrode of the plug's tip. Step 3: Look at the tool's ruled edge and find the gap's measurement. If it is too big, bend the spark plug's end with the tool to widen the gap. To make the gap smaller, push the side electrode (the metal part at the very top) against a hard service. Step 4: After adjusting, measure again. Repeat this procedure until the gap matches the specification listed in your car's manual. Step 5: Repeat with each plug. ***Installing the New Spark Plugs Step 1: Hand-tighten each spark plug in place. If you feel any resistance, stop and start over to prevent cross-threading. Step 2: Tighten the plugs with a socket wrench until snug. Do not overtighten. Step 3: Replace the spark plug wires. Usually, you will hear a soft pop when the plug wire snaps onto the plug. Step 4: Start the engine. Listen. If the engine runs roughly or doesn't start, make sure the wires are pushed all the way onto the new plugs.
