  Q:

  What special care should be taken when installing Spark Plug(s) into the cylinder head spark plug wells on Dodge Nitro?

  A:

  When inserting spark plugs in the spark plug wells of the cylinder head, care should be taken to avoid dropping the plugs and damaging the electrodes. It is important to tighten the spark plugs to the specified torque. Over-tightening can cause distortion, resulting in alteration of the spark plug gap, or cracking the porcelain insulator. Start the spark plug into the cylinder head by hand to avoid cross-threading, and then tighten the spark plugs. Examine the condition of the coil O-ring before installation of ignition coil(s) and change it if necessary; applying a small amount of silicone to the coil O-ring can prevent overlaps during installation. Complete the assembly with the ignition coil.

  Q:

  How to remove a Spark Plug and inspect the ignition coil on Dodge Nitro?

  A:

  To access each spark plug, first remove the ignition coil above it, which in turn will involve removing the required air filter tubing at the throttle body. Before pulling the ignition coil off the engine, spray compressed air around the coil base at the cylinder head, and then spray compressed air into the cylinder head opening to prevent foreign material from getting into the combustion chamber. Using a good socket, which should have a rubber or foam insert, remove the spark plug from the cylinder head and check the ignition coil O-ring for damage and replace it if necessary. Finally, check the character of the spark plugs.
