Hesitating on a 2006 Buick Lacrosse


this is for a 3.6L engine, should be the same either way. doesnt seem extremely difficult

  1. Turn the ignition OFF.
  2. Remove the ignition coil.
  3. Use compressed air in order to remove debris from the spark plug cavity.
CAUTION: Refer to Safety Glasses and Compressed Air Caution in Service Precautions .

NOTE: Clean the spark plug recess area before removing the spark plug. Failure to do so could result in engine damage because of dirt or foreign material entering the cylinder head, or by the contamination of the cylinder head threads. The contaminated threads may prevent the proper seating of the new plug. Use a thread chaser to clean the threads of any contamination.
  1. Remove the spark plug.
NOTE: Allow the engine to cool before removing the spark plugs. Attempting to remove the spark plugs from a hot engine may cause the plug threads to seize, causing damage to cylinder head threads.

INSTALLATION PROCEDURE
  1. Ensure that the spark plug gap is equivalent to the spark plug gap specification. Refer to Ignition System Specifications.
NOTE:
  • Use only the spark plugs specified for use in the vehicle. Do not install spark plugs that are either hotter or colder than those specified for the vehicle. Installing spark plugs of another type can severely damage the engine.
  • Check the gap of all new and reconditioned spark plugs before installation. The pre-set gaps may have changed during handling. Use a round feeler gage to ensure an accurate check. Installing the spark plugs with the wrong gap can cause poor engine performance and may even damage the engine.
  1. Install the spark plug.
NOTE: Be sure that the spark plug threads smoothly into the cylinder head and the spark plug is fully seated. Use a thread chaser, if necessary, to clean threads in the cylinder head. Cross-threading or failing to fully seat the spark plug can cause overheating of the plug, exhaust blow-by, or thread damage.

Tighten the spark plug to 20 N.m (15 lb ft) .
  1. Install the ignition coil.

What should the spark plug gap for a 2004 chevy malibu be?


The spark plug gap for this application is 0.60 Although, the spark plugs are Iridium plugs and are pre set by the manufacuter and should not be tampered with due to damaging the diode on the plug. The correct application for this vehicle should be AC DELC0 IRRIDIUM SPARK PLUGS.
