Spark Plug: Installation: 2.4L
CAUTION:
Spark plug tightening on the 2.4L is torque critical. The plugs are equipped with tapered seats. Do not exceed 15 ft. lbs. torque.
Special care should be taken when installing spark plugs into the cylinder head spark plug wells. Be sure the plugs do not drop into the plug wells as electrodes can be damaged.
Always tighten spark plugs to the specified torque. Over tightening can cause distortion resulting in a change in the spark plug gap or a cracked porcelain insulator.
- Start the spark plug into the cylinder head by hand to avoid cross threading.
- Tighten spark plugs. Refer to torque specifications.
- Install throttle body (if necessary). See FUEL SYSTEM article.
- Install air cleaner tube and housing.
