Default Complest pictorial for Spark Plug change.

Even with most of the stories of quick and easy success that most of the memebers have had with changing plugs, I was stil very nervous about changing my own. With some guts and encouragement form Peaty, I finally took the plunge and did it myself. I am glad that I did as well. It is as easy as they say. It did take well over an hour though. Of course I was taking pics, chasing down more batteries for more pics, going in for a coke, and chaning the plug wires as well. I will shnow some basic pics here, but if you want the professional hit: http://www.azscooby.com/ for Peaty's step by step.

Anyway, Here is what you will need:
1- 8" extension
1- 5/8 spark plug socket (crucial)
1- Swival head socket wrench
note: You can of course use a straight wrench but in order to get around a couple of the angles you will eithe need a swival socket extension or an addtional 2-1/2" extension.
1- tube of anti-seize
1- tube of dialectric grease/silicon lube don't buy hte little packets. Waste of money. Buy the tubes. The total for what you see below was like $6. In retrospect I wish I had gotten the bigger tube of silicon grease. Oh well.
4- plugs. (duh ) note:use whatever plugs you want. I like my NGK's (see review at bottom) but there is also, bosche +4 and some others. After doing a lot of research I went with what most people have been happiest with; NGK. I will not get into what is the right plug for your car, because it has been debated a million times, and I will not add to the confusion with my own part#'s. My suggestion? Go here and find out exactly form the plug manufacturer what plugs go into your car. That is what I did and am very pleased with the results.

Take out the windshield washer resovior. I have been planning this and ran myself out of fluid to make things easier for me. I took out the 2 top screws, and unhooked the pump's electrical connection. simply pinch the plug as will most automotive connections.

Since I was out of fluid I did not force the issue with the small rubber house that was attached to the tank. It was being a pain and could see that it would be a pain to get it re-attached, so I simply left it attached and laid it out of the way.

Once you get the resovior out the the way, it is fairly simple to get at the plug wires. Of course pull on the boot and not the wire. Pictured below is the forward most plug on the drivers side. The most challenging of all of them to get to. Without the wrench take the 8" extension and the plug socket and slid it into the hole. It was well designed, and has a tight tollerence. The socket slides onto the plug easily.gently push the socket onto the plug and twist untill you feel it "lock". Then attache your wrench and get it out of there. It came out pretty easily.

To put the new plug in, use only the extension and socket with the plug in the socket. Put some silicon grease on the tip and some anti-sieze on th threads. I was liberal with both and found no ill effects so far. This being my first plug change I found it was pretty neat to see that the plug was snug in the socket. It was like one long piece. Easy to work with.

Hand thread it without the wrench. It threaded very easily for me on all the plugs. Like I said earlier, they made it fool proof and make it hard for you to mess it up. It lined up percectly. Once you feel decent resistance, Put the ratchet on. And tighten her down. I liken it to a smilar resistance of a soda bottle. You want to tighten it down the same amount as a soda bottle you would leave out where kids could get at it. (I'm a parent, gimme a break ) Tighten it down tight, but not so tight that you will have problems when you change them again latter.

BTW, after the first 2 plugs I started the car up briefly to make sure I wasn't screwing it up. That did not appear to affect anything as far as getting the other plugs out.

I also put in the plug wires that I got from a fellow memeber for a big time bargain. (I would give thanks and shout out, but I do not rember his name )

Anyway, I noticed a considerable difference afterwards. It seems to rev a little freeer (sp? :P), sound and run smoother and I lost that slight misfire/hiccup it had at idle. I am very pleased and happy I did it myself.

Peaty, or anyone else, feel free to grab these pics and use them for your site.

Thumbs up thanks

wow! thanks! I'm planning on doing my plugs sometime this summer. I've already got the page bookmarked and printed out. Thanks for taking the time to do this for everyone.

You should also be checking the gap on the new plugs before putting in.
