If you replace the plugs one at a time, you will eliminate the possibility of mixing up the wires--usually not a problem, but an ounce of caution...
Buy your plugs at a parts place that will gap them for you or, better yet, show you how. It's not hard, but the gap determines the temperature at which they fire and improperly gapped plugs will either burn the plugs out prematurely or cause them to form carbon deposits, neither of which will keep your engine running smoothly.
Before you put the plugs in, put a little oil on the threads.
When you put the plugs in, begin by slowly turning each one counter-clockwise until you feel the plug drop down one thread. The will prevent cross-treading. Then turn it clockwise until you feel the %26quot;stop%26quot; point. Tighten it from there--no more than a quarter turn-- until it feels snug. Be careful not to crank them in too tight--you can damage the threads that way. Very bad. Again, you could get a buddy or one of the guys at the parts place to show to how tight they should be.
Finally, make sure that the plugs make good contact with the conductors when you put the wires back on. They're spark plugs, and they need juice.
First time's the hardest, mostly because you'll be nervous about screwing it up. But it's really pretty simple and you'll be a pro before you know it!
Can anybody guide me through changing my spark plugs in a 99 Chevy Tracker step-by-step?
the easiest thing to do would be to pick up a repair manual from a local auto supply store.
but basically remove that black cover on the top of your engine. now you will see the coil.take off the individual coil then pull up - this is the wire to the plug. Stick in the wrench (spark plug wrench) and screw out the plug. do this process for all plugs. then work in revese order to replace the wires, than the cover.
