How to Install a Honda Spark Plug
Is your spark plug not doing its job of delivering electric current from the ignition system to the combustion chamber of a spark-ignition engine? Is it busted to the point that you can't start your car? Then keep on reading. It could be compromised, detonated, under-torqued, or over-torqued. On that note, here's how you go about installing a new Honda spark plug or two to replace your compromised plugs. You should replace your damaged plugs post-haste to prevent engine damage.
What You'll Need
- Wrench set
- New spark plugs
- Spark plug puller
Step 1:Aside from the owner's manual and this guide, you can also read service books about your Honda model to help you out. You want to understand and gather as much knowledge as possible about spark plugs before doing any DIY installation.
Step 2:If your car's spark plugs have gotten a mileage of 100,000 miles, then they should definitely be changed. You'll save yourself a lot of money and trouble by changing the plugs at the first sign of trouble or even before they fail.
Step 3:Locate your spark plugs by referring to your user manual for help then inspect their current state or condition. Worn out spark plugs can result in low gas mileage, decreased overall performance, and, even worse, your engine misfiring.
Step 4:Before removing the inoperative spark plugs in question, wait until your engine has cooled down. Repairs and replacements should be avoided while your car and engine is extremely hot from use, especially with electrical items like your spark plugs.
Step 5:Take off the plug's spark plug wire. Grab it by the plug boot if you're doing this by hand (to avoid electrocution). Don't pull on the wire. Actually, it's better to have a spark plug wire puller available to avoid ripping the wire in question.
Step 6:Completely clean any debris and dirt that can be found inside the spark plug hole by blowing it off with compressed air or wiping it away (the former method is safer and more efficient than the latter method).
Step 7:Use a socket or ratchet wrench to remove the plug. Usually, the plug requires wrenches with the size of ? or of an inch. An extension might be handy too. Remove the plug by turning it to the left or counterclockwise.
Step 8:Install the new spark plug. Twist it to the right or clockwise then tighten it with the wrench you used to remove the stock plug. Connect the wire back in place; you should hear a snap once it connects.
Step 9:Torque is an important aspect of your plug installation. Your plugs should have the right torque to them as established in the user manual. Under-torqued plugs slow down heat transfer and over-torqued plugs can suffer from severe metal shell stress, resulting in distortion.
Step 10:Repeat the same steps when removing and replacing other spark plugs. You should change them one at a time instead of all at the same time so that you could keep everything in perfect order without confusion.
A spark plug is the car component that assists in igniting the compressed fuel and air mixture through the use of an electrical spark. It's also responsible for containing combustion pressure within the engine. This plug also contains a metal threaded shell that's electrically isolated with a porcelain insulator from the central electrode.
