The 5 Mistakes to Avoid When Replacing Spark Plugs

Model: (Various brands) Various
Part: Warning light – error code

When performing maintenance on your car yourself, it's easy to make mistakes, especially if you're a DIY enthusiast just starting to work on your vehicle. This brief guide reveals the 5 mistakes to avoid when replacing spark plugs: - The first mistake is replacing the spark plugs while the engine is hot; doing so risks damaging the threads, leading to much more expensive repairs later. It's better to wait until the engine cools down. - The second mistake is not cleaning the spark plug wells; dirt can enter the cylinders, damaging the internal surfaces. - The third mistake is replacing only one spark plug; spark plugs should always be replaced in pairs. - The fourth mistake is using unsuitable tools; if a spark plug is handled improperly, the gap between the centre and side electrode may be compromised. - The fifth mistake is using an incorrect torque setting during the installation of the spark plugs. Always read the manufacturer's specifications.
