Need Spark plug change instructions?

I would like to change the Sparks plug by myself but I don't know how because I don't have the instruction. My car is Honda Civic 2005.

How about going to you tube and punching in your info about changing spark plugs. You can do it, its easy!

It's not really that complicated.

First (optional) you should measure/adjust the gaps on the spark plugs. There's a gage that consists of a round thing, like a half-dollar coin, with a sort of blade that goes around it and increases in thickness. They're really cheap, and there's probably a little box of them next to the cash register at your local auto supply store. The guy in the store will happily show you how to use it.

But plugs come already gapped from the factory so if you want you can skip that step.

Now find the spark plugs on your engine (hint: they're usually on top!) Get the right sized socket (might have to buy that too) and take them out, one at a time. Screw the new ones in just finger-tight, then turn them half a turn with a wrench to crush the gaskets. Reconnect the wires.

Don't take off all 4 wires at once and get them mixed up! Pull off one at a time, put it back after you've changed the spark plug, and put it back on.

I'm sure there are vids on YouTube showing how to do this! A visual demonstration is usually more help than just a text explanation.

If this is your first time to hold tools, get someone to show you how to change the plugs. You can easily break the engine overtorquing the plugs and breaking everything else.

If the plugs are on top near the intake manifold, you need to blow off the loose debris first! Using compressed air is the best way. If you fail to do this, dirt can drop in the cylinders and cause damage.

1. Put the car in park if you have and automatic transmission or 1st gear if you have a manual transmission. Apply the parking brake.

2. Open the hood and locate the negative battery terminal and disconnect it from the battery. In the picture, this is the cable going to the battery that doesn't have a red protector covering the terminal. Tuck it away from the battery so that it can't accidentally touch the battery terminal.

3. Remove the COPs (coils over plug) off the top of the valve cover. The COPs are the 4 grey round things plugged into the black part that says "Honda VTEC". Mark each one with a white paint marker so as to not mix them up so you can put them back in the same order.

4. Under each COP is a spark plug. Using an appropriate extension and spark plug socket, remove each spark plug. CAUTION! Do not let anything fall into the spark plug hole including any dirt. It will ruin the engine.

5. Before installing the new spark plugs check and gap them to the specifications in the owners manual. They should come pre-gapped. But I think they should be 1 - 1.1mm (0.039-0.043in).

6. Apply an anti-seize compound to the spark plug threads an a dielectric grease to the part the COP plugs into the back of the spark plug before installing them.

7. Push a spark plug into the spark plug socket. Then carefully screw in the spark plug by hand. Once the spark plug is screwed in, tighten it with the ratchet with firm pressure. Repeat for the other three plugs. Do not over-tighten the spark plugs. Do not unde- tighten them either.

8. Reinstall the COPs.

9. Reconnect the negative battery terminal. Make sure you haven't left any tools in the engine before closing the hood.

10. Listen to the engine and look at the gauges for any problems when you first start the engine.

Spark plugs are a bad thing to learn mechanics skills with. They can be broken if the tools are improperly used. If overtightened, can make serious problems. You need an experienced person THERE, where YOU are, to be your mentor/helper. You also need some proper tools.

You need to check/set the gap on the new spark plugs.

Check whether your city library or local college library has an online subscription to Alldata. Look up you exact car and read about how to change your spark plugs.
