    How do you remove a stuck spark plug in a 2006 saturn vue

    The damage might have been done already. If the spark plug was over-torqued when it was installed or replaced while the engine was hot, some of the threads from the cylinder head may have gotten sheared off and stuck to the spark plug. Options are kind of limited. With a cool engine, spray the spark plug with penetrating oil, put the spark plug socket on the plug and tap it (vibration helps the stuff penetrate sometimes), let it sit for half an hour and try removing it again. Try to use the shortest extension you have and try not to use a swivel. You wanna apply as much torque as you can to the plug without snapping off the porcelain insulator so use two hands, one to apply torque and the other to hold the tool straight. When you get it out, check the threads on the plug and the cylinder head carefully. If any metal had crumbled off, you don't want that stuff getting into the cylinder. If it does get in there, you'll have to get creative with a vacuum because that stuff will scar the cylinder wall. If you did shear off some threads, most auto parts places have thread repair kits but you gotta follow the instructions carefully because those tend to be a one-shot deal. If you mess up, you might be talking to a machine shop or junkyard soon after. Good luck.

    I have a 2006 saturn vue 6 cylinder and a plug is stuck. How do you get it out wiyhput breaking it off in the head#?

    Don't worry about it breaking up. The base is all metal, not likely to break up. What is of concern is that the spark plug threads in the cylinder head don't get messed up when removing a stuck plug.
    Use some liquid wrench or penetrant around the spark plug, and let it sit for about 20 minutes. Then put socket on the plug and wrench it out. Sometimes the upper part of plug, the ceramic top, will break off, but you can still remove the base part. Buy a tube of anti-seize compound, and use it on the threads of new plugs. You will never have a stuck plug again.

    How do I locate and change the spark plugs on the 1998 Oldsmobile 88?

    There will be 6 spark plugs. 3 at the front of the car between the engine and the radiator. 3 on the other side of the engine close to the firewall. You can follow the spark plug wires to locate each plug. The engine is transverse mounted, or sideways. It can be difficult to plugs on this type of engine because of clearance problems. I use a special spark plug socket that is extra long. Instead of using a ratchet wrench, I use a 7/8 inch ratcheting box end wrench on the socket. The socket has a rubber insert to hold on to the plugs after they have been removed from the engine. Be careful when removing the spark plug wire. They get stuck on the plugs, and pulling on the wire will damage it. If you don't have a tool designed for removing spark plug wires, twist the boot, or the big end of the plug wire that slips over the end of the spark plug. Once is is loosened up, you can pull it off the spark plug. Pull on the boot, never the wire. Only remove one wire at a time to avoid getting the wires crossed. To install the plugs, get a 6 inch length of rubber vacuum hose that will fit tightly on the end of the spark plug. Use this as a handle to install the spark plug into the engine. Once the spark plug is threaded in to the engine, pull the hose off the end of the plug and use the socket and ratcheting wrench to finish tightening.

    Difficulity removing spark plug caps to replace spark plugs in 2002 GMC Yukon

    This is normal for the boots to be stuck on it is a very tight fit to begin with and the heat that is generated around them cause them to stick. Try rotating the boots back and forth twisting action as you pull up.If this doesn't work there is a tool available to remove spark plug boots at most autoparts stores.

    How to change spark plug and tools to used

    You will need a 5/8" spark plug socket, a 3/8" ratchet, a 2" X 3/8" extension, a 6"X 3/8" extension, a 3/8" universal joint, and a lot of patience. The spark plugs on an Express are very hard to get to.
    First, remove the glove box bezel (the trim around the glove box) by gently prying it off. You may need a small flat-tip screwdriver to do this.
    Second, remove the glove box (located underneath the drink holders in the center console beneath the radio), it just snaps in at top.
    Third, remove the engine cover. There are four bolts behind the glove box, remove them. Remove the left and right side lower dash panels (they snap in). Release the four clamps, and wiggle and rock the engine cover away from the dash.
    Now you get to try to remove the spark plug wires, which will be stuck quite firmly due to the many hours of engine heat. Once you have a wire off, you then have to finagle the spark plug socket onto the plug. You will have to try various combinations of universal/extension/ratchet to accomplish this, and the plugs will be stuck quite firmly as well. Do this one wire/plug at a time.
    Gap your replacement plugs to the spec in the owner's manual, usually .060".
    Installation is the reverse of removal.
    Good luck, and if this helped, please remember to vote/comment.

    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.


      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.

    The best way to check for spark is to remove a sparkplug wire from one of the sparkplugs on you engine and then take one of the spark plugs that you replaced and connect it to that plug wire. Make sure the plug is touching bare metal and have someone crank your engine. You should see a spark at the end of the plug. As far as a stuck injector you need to see if your getting spark first. Let me know what you find.
