use just a little anti-seize on threads
Anti seize on the threads, and dielectric grease on the plug wire end. Check manufacturer reccomendations as some are against using anti-seize grease. Also anti-seize grease which contains copper could be not compatible(corrosion) with aluminium alloy engine head.
no
My guess is that it is a 3.1L motor correct?? If so, you remove the spark plug wires from the engine bank closest to the front ( left bank ) then remove the plugs...the rear ( right bank ) is not acessable unless you remove the "dog bones" from the left bank. there should be a small bolt hole under the dog bones to put the bolt that you had removed into it to pull the engine closer to the front. then remove the wires from the right bank and remove the plugs. make sure all the spark plugs are properly gapped using a spark plug gapper.. highly recommend that you use dielectric grease on the insides of the spark plug wire boots to prevent seizing and corrosion, then on the spark plugs use a small amount of anti-seize grease on the threads of the plugs also to prevent seizing and corrosion
why do my spark plugs smell like gas but the conductor is dry just the threads smell like gas and are also wet
sounds like you have stripped the threads, if so you need a " heli coil " thread repair..and follow directions. those threads will need to be repaired or retapped,and always start the threads on your spark plugs by hand and not with a wrench.
You do not have to but it will be very good if you place a die-electric grease on points where ignition wires contact spark plugs and distributor/coil pack.
Adding a small amount of copper grease to spark plug threads primarily prevents the plug from rusting to the cylinder head and in Aluminium head cases, prevents 'cold welding'. The copper content also allows for greater earthing properties and contributes a very small amount to create an air tight seal.
If you have oil pooling in the spark plug wells from a leaking valve cover gasket or sloppy top-up, before you pull the old plugs use an engine cleaner such as Foamy Engine Brite(R). Hose the engine off while it is cool then start it up and run it to boil off the water. Any little bit of oil left after that is not a concern. You should put a little anti-seize grease on the threads of the spark plugs going into an aluminum head, anyhow. A little oil in the threads will serve a similar purpose.
Remove the engine covers and carefully remove the ignition wires from the spark plugs, there are 12 of them, then remove the spark plugs with a 5/8 plug socket. Make sure the gap is correct on new plugs put a bit of anti seize on the threads then install the new plugs...
Use AC / Delco Platinum or Iridium long life spark plugs & use a "anti-seize" compound on the threads on installation. Best of luck!
I would recommend the OEM spark plugs, AC/Delco. Excellent plugs.
Spark plugsfor a 98' explorer, if you remove the wheels there is a panel that can be removed behind the rotors that gives you acces to all of the spark plugs. i was changing the brake pads on my 98' explorer and it needed spark plugs to, and i saw this panel, removes it curiously and whala, there were all of the spark plugs! Carefulbe very careful with this one, apparently these have a ton of troubles with the spark plugs BLOWING from the heads.. apparently the Alum. head where the spark plug screws into only has 3 threads for the plug to seat in, which is not sufficient for holding these plugs in very well..The reason I am bringing this up is if you try to replace these plugs yourself and if you OVER TIGHTEN the plugs, you can strip the threads very easily.The end result of strippen the threads on the heads is a very expensive head replacement @ $3KAlso, I looked on my '98 expedition and I don't know how it is possible to reach some of these spark plugs. (the spark plugs are located above the valve covers and UNDER a "COP", which instead of a typical spark plug wire you will have a Coil with a couple of wires coming from it.)Better YetTry this sitehttp://www.mattstruck.com/sparkplugs/sparkplugs.HTML
