How to Check Your Spark Plugs

For the engine of any car to operate optimally, it requires good spark plugs and these plugs need to be replaced after approximately every twenty thousand miles. However, their condition needs to be checked after about ten thousand miles. This is normally done when the car goes for a tune up. It is also recommended by the manufacturer that the spark plugs are checked regularly incase of any splits, corrosion, cracks or any other damage that would interfere with the car’s performance. Checking the condition of the sparks does not require a qualified mechanic and the procedure for checking spark plugs is as follows.

First, pull the release lever for the hood which is located below the dash board. This will enable the hood to open. Move to the front of the vehicle and open up the hood with the latch underneath it. The spark plugs in four cylinder engines are found on a row that is on one side of the engine and cars which V-shaped engines have the plugs are on two sides of the engine. They need to be removed one at a time and thereafter; the plug wire should be replaced before checking another plug. The plug wire should then be pulled at the point where it connects to the plug. A rubber boot at the wire’s end is then pulled gently so as not to damage the plug.

Remove the plug with a ratchet and socket by twisting it counterclockwise. An extension of the ratchet and socket may be needed if the plugs are in a deep set and not easily accessible. Any dirt on the spark plug should be wiped or blown away to prevent anything getting in the cylinder. A spark plug in good condition should have a light coating of brown grayish deposits. If the plug happens to have a black coating or the core nose looks damaged then replacement is needed.

To carry out gapping of the spark plug, the correct gap should be determined from the car’s manual. It may also be indicated on the hood of the car. Put the gapping tool in the space that is between the centre electrode and the side electrode of the plug tip. Study the ruled edge of the tool and do a gap measurement. The gap can be adjusted by bending the tip of the spark plug to make the right size. This should be done for every plug. When putting in the new plugs, hand tighten them, and if resistance is felt then begin again to avoid cross threading. Socket wrenches are used to tighten them until they are securely in. The plug wires also require regular replacement. If gapping is not done appropriately, a car may not run properly and the right model of plugs should be bought for effective performance. The final step is to start the engine to find out whether the engine runs smoothly. Regular checking of spark plugs is vital to ensure that overall car safety is maintained.

What is the most handy tool to own?

I am a mechanic, but I have always wondered what single one tool is the most commonly used and handy to have? A socket does not count because you need a ratchet to make it work. And no choosing vice grips because that is my answer. I am just curious to see your opinion. Thanks

Oddly enough...a leatherman. For some reason it always get's used.
