Thanks.How do I change SPARK PLUGS?a 5/8 or 9/16 socket an rachet extstionHow do I change SPARK PLUGS?A ranch and an 3h socket.How do I change SPARK PLUGS?Depending on the spark plug itself, you will need a screw driver, a socket wrench and some gloves (if you dont want your hands to get dirty or irritated by cold/hot metal)



1) Take the plug out of the package (Be sure it fits correctly into the required position)

2) Be sure your car is not running while you are doing the exchange/replacement

3) Remove the old plug from its socket

4) Put in the new one and screw it in tightly with your hand before using the socket wrench and/or screw driver to tighten it further.

5) Once its tight, close the spark plug box (If it has one) and make sure its secure..



ALL DONE

You need a sparkplug socket to remove and replace the spark plug. It is tight enough to keep it from working its way loose. You have the plugs. You should put antiseize compound on the threads of the new plugs before you put them in, but I use a couple of drops of clean motor oil. You should have a gap tool to make sure the gap on the sparkplug electrode is the right size. If you're using platinum plugs they say don't try and adjust their gap. They're usually right, but I always check to make sure.



Remove the spark plugs only one at a time to make sure you don't have a chance of mixing the wires up. Do the job with the engine cold, if you can.



Take off the first wire from the first sparkplug by twisting its rubber cover to make sure it doesn't stick to the plug, then pull the connector loose from the sparkplug. Next, carefully slip the socket down onto the sparkplug and loosen it. If it seems like it doesn't want to turn freely, turn it back and forth a bit, then unscrew it all the way out, taking care to not drop it while you lift it out of its hole. Take time to look at the condition of the plug. It should be dry, not oily or wet with fuel. If there is any water on it you have a serious problem with the engine. It should be brown like light coffee, or grey, but not black and sooty. Take a new sparkplug out of its box and look at it to make sure its gasket is on it and all the way off the threads. Look at the electrode and make sure it is straight. Is some clumsy clerk dropped it in the store it could be bent. That doesn't happen often, but this is your chance to be sure. Measure the gap to make sure it's not open too much or closed too much. Standard plugs can be bent open or closed as necessary. Put a drop of antiseize compund on the threads, wipe off the excess .Here's where you need to be careful: Slowly start the new plug screwing into the hole by hand to make sure it goes in straight. Make certain this is straight. Easy is right. Hard is always if it's crooked. Never force it. Screw the sparkplug all the way down with the socket, then tighten it a half to 3/4 turn more. I use a torque wrench to get it to 14 foot pounds, but that's just being very cautious. As long as its tight enough to stay in will do. Try and remember how hard the old one was to lossen and that's how tight to put the new one in. Replace the wire to the new plug, making sure it is firmly attached and you're done. Do the next plug now, the same way. You'll be glad you don't have two loose wires and wonder which plug they came off off. There is only one right way to put them, so the one-by-one method is foolproof.



If a sparkplug won't come out with your hand tools, there is a real problem you'll need an experienced person to assay. The last thing you want to do is start out with a simple job and end up having to take off the head to have it repaired. Think of the last time you opened a real tight jar. It shouldn't be harder than that. You can learn everything you need to know about doing this basic job in a Chiltons Auto Repair manual. There is very little else you would need to do with that particular engine to keep it running well. Replace the air filter and change the oil and oil filter next chance you have time, unless that's been done in the last 6 months. A good investment, however, is to buy an OBD II code reader so you can tell what's wrong anytime the check engine light comes on. It'll cost you about $100 and it just about costs double that anytime you go to the service dept to have work done. You're saving over $100 changing your own spark plugs. Reward yourself.
