How to Change Spark Plugs Ford F150 4.6L Engine?

Changing spark plugs on your Ford F150 4.6L engine can be a relatively simple task. The spark plugs are located in various places throughout the engine, but the process is the same. Start by inserting the spark plug deep into the spark plug well. The spark plug is then connected to a coil on the other end. After inserting the spark plug into the correct hole, tighten it until it is seated properly.

Before removing spark plugs from a hot engine, make sure you use a carburetor cleaner. This will loosen up carbon deposits in the carburetor. Then, unscrew the spark plugs from the cylinder head by alternately tightening and loosening them. The porcelain insulator is still attached in the cylinder. If the spark plugs are stuck, apply more penetrating oil to loosen them.

Next, remove the spark plug. The porcelain shell is typically covered with carbon, rust, and corrosion. This makes it difficult to remove spark plugs, and the lower shell of the plug may break off. You may need a special Ford plug extractor tool to safely remove the spark plug. If this is your first time changing the spark plugs on your F150, you will want to consult a manual to ensure you follow the instructions carefully.
