To start a car, an electric current is delivered to the ignition by the spark plugs. If they were not functioning correctly, your car would not start.
In comparison to most other car parts, they require very little maintenance. Honda says spark plugs should be changed every 30,000 to 40,000 miles.
Your Honda model and make, as well as your driving habits and average driving conditions, will determine how often your Honda should be serviced. If you’re unsure, you can find this information in your Honda Civic’s owner’s manual.
You can have trouble starting your car if your spark plugs are faulty, as faulty spark plugs compromise the entire ignition system. In order to keep this crucial system functioning correctly, every Honda driver should ask: When should I change my spark plugs?
Check the spark plugs regularly to ensure there is no obstruction and your engine is running smoothly. If the plugs are fouled or worn, replace them immediately.
How To Change Spark Plugs 2012 Honda Civic?
The HT leads on the spark plugs should be removed from their housings. Taking them out shouldn’t require much force. Grab them as close to the casing as possible and lift them out without pulling them by the leads.
Pro Tip: Replace your spark plugs one by one. As a result, you can tell which lead goes to which spark plug without getting confused. Misfiring can occur if you make a mistake here. It would be helpful if you put a sticker on each HT lead so you will know where each one sits if you remove them all at once.
Step 1
Removing the old spark plugs from the engine requires using the 5/8 socket head. Please don’t force them, as this could damage their threads or cause them to break.
Get a flashlight and check around the plug base for dirt and debris before you remove it. If you find anything, clean it up. None of this gunk must fall into the engine when removing the plug. All it takes is a little compressed air to throw out any gunk.
Step 2
After removing the spark plug, measure the distance between its points. By doing so, you can determine how badly worn they are. Your car’s manual will tell you the ideal distance between the two points; if not, search online.
It’s always better to replace them if the gap is okay, but it’s not always necessary. Spark plug-gap tools can be purchased online cheaply, and I recommend that everyone own one.
Step 3
Put some copper grease or anti-seize on the threads of the new spark plugs before installing them. The next time you need to change them, you will find it much easier to get them out this way. Wipe away any excess on the plugs and be sparing with it.
Step 4
The new plugs should be inserted into their housings and tightened. Be careful not to tighten them over. It can also lead to their breaking or make it impossible to remove them in the future.
Step 5
The HT leads should be reattached in the correct order. You should only need to press them into place with minimum force. To prevent any misfires, ensure they are in contact with one another.
Final Step
Check if the car fires correctly by starting it.
Check the Spark Plugs
If your car has recently been serviced or you have replaced the spark plugs, now is an excellent time to check them. Use a plug wrench to remove the old plugs and replace them with new ones.
Ensure the gap between each plug is about .025 inches (6 millimeters). Reconnect the wires by following their colors from left to right and putting them in the correct positions on the plug connector block.
Replace any damaged electrical connectors and tighten any screws.
Change If Worn or Fouled
If the spark plugs look worn or fouled, it is time to change them. Use a replacement tool that fits your car and remove the old ones. Clean off all the electrode deposits with a wire brush before re-installing them into your engine chamber.
Make sure you use new electrode wires if installing new spark plugs, as these can heat up and cause arcing during combustion. Follow the instructions for installing new spark plugs to achieve the best performance from your Honda Civic.
Disconnect the Battery Cable
To disconnect the battery cable, removing the negative (-) and positive (+) cables from the battery is necessary. Next, locate the two clips that hold each cable end in place.
Press down on each clip until it pops out of its hole, then pull both cable ends off the battery. Finally, reconnect each end of the new wires to their respective clips on either side of the battery and tighten them into place with a wrench or pliers.
Remove the Front Wheel Bearings and Hub Caps

Now, you can lift both bearings and retainers by gently pulling them straight from their sockets while holding onto one end of each bearing (the race).
Once everything has been removed, clean all parts thoroughly with soap and water before reassembling in reverse order.
