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.

how to change the spark plugs on the 3.0


1. Pull the hood release lever located under the dashboard.

2. Walk around to the front of the car, reach under the hood, find the latch and squeeze it. Open the hood.

3. Find the spark plugs, located in a row along one side of the engine (on an in-line four-cylinder engine) and attached to thick wires, called spark plug wires. Cars with V-shaped engines (which can have four, six or eight cylinders) will have spark plugs and spark plug wires on both sides of the engine.

4. Change one spark plug at a time, always putting the plug wire back on before changing the next spark plug.

5. Pull off one spark plug wire where it attaches to the plug. There is a little rubber boot at the plug end of the wire; pull on this part. Pulling higher up on the wire can damage the spark plug wire and cause it to separate.

6. Blow or wipe away any dirt or debris around the spark plug. You do not want anything to fall into the cylinder while the spark plug is out.

7. With the spark plug socket and a ratchet, remove the spark plug by turning it in a counterclockwise direction. You may need an extension for your ratchet if the spark plugs are deep-set or not directly accessible. Ratchets with flexible heads are especially helpful for hard-to-reach spark plugs.

8. Check the spark plug to make sure it needs replacing. A good spark plug should be lightly coated with greyish brown deposits. If heavy deposits are present, if the spark plug is black or if the electrode or core nose are damaged, the plug needs to be replaced.

how do i replace spark plugs on 2004 subary forester


Replace one at a time. Don't remove all the wires at once or the firing order will be messed up.
Make sure spark plug area is clean so no debris will fall inside the cylinder.
Remove plug wire by pulling it off by the boot and not the wire itself.
Then with extension(s) spark plug socket and socket wrench, turn them counter-clockwise until they are out, put new plug in and tighten clockwise. It may be easiest to start them by using your hand instead of the socket wrench itself. Make sure they start going in fairly easily. If they feel tight right away, the threads may not be seating right and they can get cross-threaded.
Tighten completely, don't over tighten but not loose, just snug. Then push boot from plug wire back on and move to the next one.
