The housing has the coils inside it. THe spark plugs are on the engine and not inside the housing. ull see metal tips protruding form the housing..those tips make contacts with rubber boots on the top of the engine and the plugs are under those rubber boots. So basically once u move the housing (usually looks white underneath, ull need to look at the spot where it fit on the engine. Use a flashlight and ull see 4 rubber boots and under those boots are the spark plugs...the rubber boots also have a plastic insulator on them..when u want to remove it, just pull on the rubber with pliers or something without pressing on the hard plastic as it will crack. THe plugs are under the boots and ull need an 6 inch extension and socket to get them out. Spark plug gap on it should be .06..confirm on the manual.

WHERE ARE THE SPARK PLUGS LOCATED ON MY 1999 PONTIAC GRAND AM


Hi. here's the procedure on how to replace your spark plugs. Spark plug location is in this procedure.

  • Park the car in cool, shady area and allow the engine to cool.
  • Step 2 Remove the parts of the Grand Am engine that hinder access to the spark plugs. For a 2.2 L engine, remove the ignition coil housing. For a 2.4 L engine, remove the bolts that hold the retaining ignition coil and disconnect the electrical connector. Pull the assembly straight up and away from the engine to remove it. For a 3.1 L engine, remove the air cleaner. For a 3.4 L engine, remove the windshield wiper module cover and rotate the engine for service access to the rear spark plugs.
  • Step 3 Locate the spark plug wire and grab it by the spark plug boot. Twist the boot in both directions and pull back to remove the wire.
  • Step 4 Insert the spark plug socket over the old spark pull and unscrew it from the cylinder well. Remove the old spark plug.
  • Step 5 Lubricate the threads of the new spark plug and screw it into the cylinder well.
  • Step 6 Test the tension and adjust it to the required setting. It needs to be 15 ft-lbs. for a 2.2 L engine, 16 ft-lbs. for a 2.4 L engine, 13 ft-lbs. for a 3.1 L engine, and 11 ft-lbs. for a 3.L engine.
  • Step 7 Reconnect the spark plug wire and twist it to lock the plug in place.
  • Step 8 Repeat Steps 3 through 7 for the remaining spark plugs.
  • Step 9 Replace all of the parts that were removed from the Grand Am in Step 2 to reach to the spark plugs.

    How do you remove the ignition coil


    Each ignition control module (ICM) has the following circuits:
    An ignition 1 voltage circuit A chassis ground An ignition control circuit for each cylinder A low reference circuit
    The PCM controls spark by pulsing the ignition control circuits to the ICM to trigger the coils and fire the spark plugs. The PCM and ICM are internally protected against shorts to power and ground on the ignition control circuits.

    The spark plugs are connected to each coil by a short boot. The boot contains a spring that conducts the spark energy from the coil to the spark plug. The spark plugs are tipped with platinum for long wear and higher efficiency.


    Ignition Control Module (ICM) Connectors

    Where are the spark plugs located on the 2004 alero?


    is located over the cylinder head.theres no difficultyto replace them your self. recommend replacing them when the engine is cooled down because you could damage the spark plug thread when the engine is hot. all you have to remove is the ignition coil housing to replace them and there you will see the spark plugs.

    Replace Spark Plugs


    What size engine have your behicle?

    2.2L Engine
    1. Remove the ignition coil housing.
      NOTE Remove any water and debris from the spark plug holes before spark plug removal with compressed air. Remove the spark plugs with a spark plug socket.
    2. Inspect the spark plugs.
    To install:
    1. Gap the spark plug, using round wire type spark plug gap gauge. Adjust the spark plug gap to 0.045 in. (1.14mm).
      WARNING DO NOT coat the spark plugs with anti seize compound. Over torquing could occur and damage to the cylinder head threads may result.
    2. Install the spark plugs with a spark plug socket. Tighten to 15 ft. lbs. (20 Nm).
    3. Install the ignition coil housing.


    2.4L Engine
    The spark plugs on this engine are located under the ignition coil and module assembly. To gain access to the spark plugs, the coil and module assembly must be removed. On the 2.4L (VIN T) engines, the spark plugs are platinum and require replacement every 100,000 miles (160,900 km) or 60 months which ever comes first.

    1. Disconnect the negative battery cable.
    2. Remove the 4 bolts retaining the Electronic Ignition (EI) coil/module/cover assembly (depending upon vehicle application), then detach the electrical connector. Remove the assembly by pulling it straight up away from the engine.

      5cdc221.jpg

      Fig. To remove the cover, unfasten the four bolts, then pull the assembly straight up from the engine
    3. If the connector(s) sticks to the spark plug, use spark plug connector removing tool J-36011 or equivalent, and a twisting motion to detach the connector(s) from the plugs.
    4. Clean any dirt away from the spark plug recess area.
    5. Remove the spark plug using the proper size socket, extensions and universal joints, as necessary. Hold the socket or the extension close to the plug with your free hand, as this will help lessen the possibility of applying a shear force which might snap the plug in half.
    To install:
    1. Lubricate the threads lightly with an anti-seize compound, then start the four spark plugs by hand. Tighten the plugs to 14 ft. lbs. (19 Nm).
    2. If removed, install any the plug boot connectors that may have stuck to a spark plug to the EI assembly.
      NOTE Check to make sure the spring terminal is inside the boot.
    3. Install the EI coil/module/cover assembly to the engine, while carefully aligning the boots with the spark plug terminals, by pushing the assembly straight down.
    4. Apply Loctite®thread locking compound, or equivalent to the cover bolts. Install the bolts and tighten to 16 ft. lbs. (22 Nm).
    5. If removed, engage the ignition cover electrical connectors.
    6. Connect the negative battery cable.

    I really hope helped with this (remember rated this help) Good luck.

    I keep getting a notice that the #2 and #4 cyclinder is misfiring. I went to change the plugs, but could not locate them from the top of the engine. Where are the plugs located at?


    Need to remove upper intake manifold to reach valve cover close to firewall. 1) The location of spark plugs 456 are under the plastic shield in front of the engine. It takes an 8mm socket to remove the three bolts holding the shield once the shield is removed you will see a coil for each spark plug. Use the 8mm socket and remove the coil and rubber boots. You will now see the spark plug (note there are not any spark plug wires). 2) The location of spark plugs 123 are located to the rear of the eng. You have to remove the air intake manifold in order to get to the spark plus. Remove the throttle wire then remove the other items on top of the intake manifold. 3) Loosen all the bolts holding the manfold. 8mm socket-- I think three in front and three in the middle. Remove the EGR valve mounts so you can slide the manifold out. Disconnet all vacuum lines from manifold and the air filter inlet closet to manifold. Just take a general look and ensure you have all wiring and tubing disconnected then slide the manifold off the eng and EGR valve. NOW MAKE SURE you cover all intake holes (leading into the engine) with paper towels to prevent droping screws etc into the engine. Then follow step 1 above

    Remove the securing bolt for the spark generator--each plug has one--I think it is 10mm-then withdraw the unit and the spark plug is way down there--you may have to remove the cross brace to access No 3 I think it is.

    1989 tOYOTA CRESSIDA sAPRK PLUGS WELLS. OIL IN THE SPARK WELL


    The 7MGE has 2 separate valve covers/gaskets with 8 screws holding each cover that will loosen over time.
    Find the phillips screws holding on the covers and retighten snugly by hand do not overtighten!
    Pull plug boots/wires by the boot not the wire and use paper towels or rags on a long screwdriver etc to absorb the oil from the wells.
    Carefully clean plug boots with spray brake cleaner (avoid spraying anything but the boot) and let dry.
    Apply 100% silicone grease to inner boot before reinstalling to allow future removal without damage.
    If your engine is particularly dirty you may need to remove the covers first and clean all mating surfaces then reinstall.
