How do you change the plugs and wires on a 2002 Chevy Silverado?

I want to change the plugs and wires on my 2002 Chevy Silverado. It alomost has 100,000 on it. I don't want to pay 400.00 to let someone do it when I can change them myself for under $50.00.|||There are short wires that go from each coil assembly to each plug, they are replaceable, just pop the old one off and the new one on. Spark plugs are no different than ever, except that if you use the wrong style of gapper, or are careless, you could destroy the platinum or iridium electrode. Get a wire style gapper, and bend the electrode with a gapping tool, not by forcing the gapper wire into the gap. You don't have a cap or rotor on your vehicle, so don't worry about that. the coil over plug ignition your vehicle is equipped with uses the signal from the crank sensor and the computer to determine spark timing, not an ancient distributor. Be sure to use a small amount of dielectric compound in both ends of the plug wires to seal them from water, and keep them from sticking to the plug or coil.|||If you can buy decent platinum plugs and good wires for fifty bucks then all the power to you. Sounds like the ones you're going to buy are cheap things. Remember you get what you pay for.





All you have to do is remove the plug wires from the spark plug and on the same cylinders coil assembly. Remove the spark plug and discard after inspecting it as this can tell you what's going on inside there. Then align the electrodes and gap it to the spec. Install into the hole and spin it in with your fingers or a vacuum hose until it bottoms. Then torque it in with the special spark plug socket you've already purchased. Redo for the other seven. Done except for the fuel filter.|||Its easy to strip the threads on a warm engine (most are aluminum now), not to mention the discomfort of touching warm metal. I usually buy plugs a day before I'm off for work and change it the next morning.|||One at a time on a cold motor. don't forget the cap and rotor aka: first air gap.
