Spark Plug: Installation: 3.2L

CAUTION:

Handle the spark plugs with care. Do not drop or force the spark plugs into the wells, damage to the electrodes or porcelain body may occur. Always start each spark plug by hand in order to avoid cross-threading the spark plug in the cylinder head.

Always tighten spark plugs to the specified torque. Too much or not enough torque will cause damage to the cylinder head or spark plug and may lead to poor engine performance.

    CAUTION:

    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.

    CAUTION:

    The spark plug tubes (1) are a thin wall design. Avoid damaging the spark plug tubes. Damage to the spark plug tube can result in oil leaks.

  2. Start the spark plug into the cylinder head by hand to avoid cross threading.
    CAUTION:

    Spark plug torque is critical and must not exceed the specified value. Overtightening stretches the spark plug shell reducing its heat transfer capability resulting in possible catastrophic engine failure.

  3. Tighten the spark plugs to the proper specifications. Refer to SPARK PLUG SPECIFICATIONS  .
