Car Maintenance 101: How To Replace Your Vehicle Spark Plugs? Knowpia

When it comes to candidates for DIY replacements in a vehicle, spark
plugs are one of them. Over time, spark plugs get worn out and
thereby need replacements, so that your car continues to perform
great. Worn-out spark plugs if not replaced within a stipulated period
leads to scenarios such as poor mileage or weak acceleration.

Learning to replace your vehicle's spark plug all by yourself will not
only help you to conserve your car in the best possible manner but
also save on labour costs. Thus, to assist you with the same, we have
formulated this guide containing all the essential steps that you need
to perform in replacing your vehicle spark plug.

Pro Tip: If you have a car that comes with a standard engine, then the
process of replacement will be relatively easy. But, if your vehicle is
using a more advanced engine, such as V6 or above, then the procedure
can become challenging. During times such as this, it’s better to consult
a professional.

Method To Replace The Spark Plug In Your Vehicle

1. Clear The Place

According to professional services for cash for cars in Adelaide,
before you decide to replace the spark plug, you must clean the area
around it. You can use a painting brush or a compressed air can for
the same. Loose dirt or debris can easily get into your car engine
interiors when you proceed to change the spark plug. So, ensure that
the place is neat & tidy. After that, remove the air cleaner assembly &
vanity cover.

2. Remove The Coil For Ignition

Once you've cleaned the surrounding area of your vehicle engine
where the spark plug is located, it's time to disconnect the electrical
connector by either pulling up or depressing the locking tab. Only
then, you'll be able to unfasten the connector off the coil. After that,
you have to remove the entire coil as well as the boot assembly.

Some car systems might have a detachable spring & rubber boot. In
case your car has one, then you have to use a pair of pliers that are
needle-nose in nature.

3. Unscrewing The Main Plug

After you've removed the ignition coil, it's time to remove the main
plug. But, first, you have to clean its surrounding area and get rid of
any dirt or debris that might be present. Once done, you have to slide
the ideal spark plug socket over the plug and then proceed to rotate
the plug, in a counter-clockwise direction to loosen the plug. It can be
possible that you might require an extension arm, especially if the
spark plug is located deep inside your car's engine compartment.

4. Measuring The Gap

To ensure that you’ve got the right size, you have to use a wire-style
gap gauge for the measurement. Once the measurement is deemed to
be correct, you then have to slide the wire gauge in-between the two
electrodes.

5. Using The New Plug

One of the most critical things about a spark plug is getting the
correct amount of torque. And that's why we suggest always using a
torque wrench while also sticking close to the recommendations of
the car manufacturer. If the torque doesn't reach sufficient levels,
then the spark plug can get blown up and destroy the threads. On
the other hand, employing too much can make the spark plug
distorted.

6. Lubing The Spark Plug Boot

It’s suggested that you apply a very thin coating of dielectric grease
around the insides of the spark plug before you proceed to re-install
the coil. Using the grease means that you’ll be able to cut down on the
misfires and it’ll make it easier to disconnect the spark plug boot
later on.
