    I assume that you sprayed a penetrating oil to help? Try Winzer TSM750 spray and allow to soak, then reapply.

    Spark plug cable is broken. The wire in the cable is still attached to the spark plug. I've tried pulling it but it is very tightly attached to the spark plug. I cannot find the appropriate socket...

    Get a suitable pair of plyers, grip the plug wire where it is thick, on the jacket that is on the plug, and pull hard. Maybe twist a little, but not sideways, as you risk breaking the plug. It should come off.
    What may happen is that you will get all the rubber, and the metal locking tap will stay on the plug. Then use a pair of needlenose plyers to remove it.

    The plug size is usually a 13/16 or a 5/8.

    Don't really worry if you break the ceramic part of the plug, you can just remove what is left with the socket, and put in a new plug.

    Trying to change spark plugs. Cannot remove spark plug wire. How can I do this?

    go to a parts store, they sell two different types of puller tools which pull the boot off the plug, instead of ripping the wire out of the boot. it is 7 and if your mileage is near 100k you may want to do the plug wires also. get a real set made for the engine, not cheap universal wires.

    How to change spark plugs

    Those are as easy as they come these days. Mark each spark plug wire with a piece of tape with the cylinder # written on it, so as not to mix up the wires. Remove each spark plug wire by firmly grasping the wire by the boot (do not pull on the wire) and twist it back and forth a few times while pulling slowly. It should pop off without a great deal of effort. If it is seized and it breaks, you will have to replace the wire, or at the very least replace the terminals (if you can get some). Use an air hose and blow around the base of each spark plug to dislodge any loose dirt that could fall into the cylinders (not absolutely necessary, but a good idea). Remove each spark plug with a spark plug socket and extension and ratchet (I forget which size socket, it's either 5/8 or 13/16). Check the gaps of each new spark plug (typically around 0.035 in). re-install each new spark plug by hand (do not cross-thread them) and once you have ensured that the plug is threaded in properly, tighten the plug until it seats, and then tighten an additional 1/16 of a turn. Repeat this for the remaining plugs. Re-install wires to the corresponding spark plugs. You're done!

    I need to know how to change the back three spark plugs on my 2008 ford edge , do i remove the get to them, is it safe

    Yes, you will have to remove the intake manifold. If you are mechanically inclined, it's not that hard. Looks complicated because of all the wires and hoses. Just take your time, keep track of everything you do, take notes if you have to, so everything goes back together the same way it came apart. Since you are going to all this trouble be sure you buy a premium spark plug. I wouldn't use Champion or Ford products. NGK Iridium would be my choice if they are available.

    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.

    How do you change the spark plugs on a 1996 jeep grand cherokee

    You have the item in front of you .
    Find the spark plug wires do the replacement one at a time. Yep clean if you can. You need the correct tools a a 5/8 socket a 12 inch or better extention a btraker bar or/and a ratchet,
    Pull the plug wire and try to work around or remove any obstruction for the time being also for sparkplugs that are located in a well use a magnetic grabing tool these rest is a counter clockwise removal and a clockwise install. Be sure not to over torque the installation
    use a 6 inch ratchet and went the plug is snug cup your one hand over the crnter of the ratchet and tighten it as tight as you would a pickle jar cap. You shall feel the seating of the sparkplug washer.
    If you are a real strong fellow use t fingers technically this is where specifications can come in handy from the library in foot pounds

    Spark plugs

    Have u ever changed plugs before? Do u have any tools? You will need a spark plug socket, which is especially designed for this purpose, it will help to prevent damage to the plugs when u remove and install them. Also a ratchet wrench for the socket, and depending on your vehicle, u may need an extension. Purchase manufacturer recommended plugs (check your owners manual), you have to check the 'gap' of the plugs before installation, so u need a 'feeler gauge' or spark plug gap tool available at parts stores. Plug gap is set at the factory, but sometimes during shipping and handling they get banged around, so u have to check to make sure the gap is correct. 1st remove one plug at a time (so u don't mix up the order). To remove grab the spark plug wires, grab the 'boot' (the area of the wire that fits over the spark plug), push in, twist (does'nt matter which direction)and then pull out to remove. U don't want to yank on the wire, u can damage the the wire, so make sure u r twisting/pulling as close to the plug as possible. Once the wire is disconnected, remove the spark plug. Insert a new plug, by putting it in the socket, then by hand (not attached to your ratchet wrench yet) carefully screw it in (do not force it!). Once it's hand tightened, put the ratchet on and tighten snuggly (don't use brute force!) check the tightening instructions on the spark plug box. Reattach wire, proceed to the next plug. Aren't glad u don't have a 12 cylinder engine? How many miles on your Passat? If it's approaching 100k, u should also change your spark plug wires. Good Luck! Let me know how it goes. countrycurt0
