Depending on weather its a V6 or 4cyl the are in the center of the engine cover(s) in a row, if its a 4cyl pull the 4 plug leads out and a long spark plug wrench will go down the hole to unscrew the sparkplugs, if its a V6 then unscrew the 6 screw and the pull out the 6 coils from the center of the engine covers to reveal the spark plugs

How do you change spark plugs


Hi Gary!

If you got a CAR and not a truck, there are a few things you need to pay attention to when replacing spark plugs.

You need to make sure your spark plugs are the issue for whatever the problem is.
Take a 16mm SPARKPLUGS spanner (it's a special sort of tool that you buy in the shop, unless you have it, don't bother to try with anything else, or your could do some damage), unplug one of the cables attached to one of the sparkplugs (make sure you don't unplug more that one, so you won't mess the order), take your magic tool (sparkplug socket spanner or whatever it is called) fit it on top of the sparkplug, (listen for the clicking) and then twist it left until the sparkplug is out.

Have a look to your sparkplug, and see if there is any carbon on it (if it's black, it has to be replaced/sandpapered)

repeat the operation to the other (alledgedly 3) sparkplugs, naking sure you DO NOT MESS UP the order of the cables that connect to the sparkplugs.

If finally you've decided it is time to replace the sparkplugs, under NO circumstances, replace less than ALL of them. (unless you replace them on the car of someone you don't like)

I drive a 95 toyota 4 runner.I would like to know the right way to check my sparkplug wires if working p roper.


You can fabricate a tester from a 6 inch long mongol pencil. Sharpen one end and drill a 1/8" hole in the middle. Now remove the sparkplug wire from each sparkplug and insert the pencil onto the sparkplug wire with the dsharpened end connected or touching the ground or any metal part of the engine. Start your engine and you should see sparks jumping on the drilled hole on the pencil which indicates that your spark plug wire is okay.

Whats behind spark plugs on a 4.3 liters gmc pick up


Directly behind your sparkplugs are the pistons. If the sparkplug is damaged, it was either the wrong plug and was too long (the piston was hitting the plug), or there is foreign debris in the engine chamber!

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!

How do I remove the rear three spark plugs on a toyota avalon 1998


Hi, to change spark plug first remove coil over connecting clip ensuring to depress connector release. Next remove coil over retaining bolts. Remove coil over carefully directing coil toward driver side until rubber end able to flex out of sparkplug access tube. Remove sparkplug using sparkplug socket with rubber insert. Had to remove ratchet to gain enough clearance. At this point you should be able to remove sparkplug by tilting extension & socket toward drivers side of car. Then lay horizontal & remove toward passenger side of car. If unable to gain access in this manner you probably have too long an extension. Take care as not to damage spark plug coil over as they are considerably expensive.

How to replace spark plugs for 1999 ford contour


to replace spark plugs remove spark plug wire boots. use special sparkplug socket or else you can break the sparkplug. to remove turn ratchet counterclockwise remove all four one at a time, make sure that the sparkplug gap is correct. most plugs come pregapped...read the box it will tell.you. do not overtigheten plug once it has fully seated give it a good snug....if you do one at a time you dont need to mark the spark plug wires. if you mix up the wires your car will back fire which could cause severe internal damage.

I HAD #3 SPARK PLUG BLOW OUT OF CYLINDER. HAD IT REPAIRED AND ALL NEW PLUGS, FUEL FILTERAND PCV PUT IN NOW TRUCK HAS A VERY FAINT ROUGH IDLE. ANY IDEAS


#3 sparkplug is not firing at peak performance.
The engine block sparkplug hole had to be re-threaded in order to accept an adapter for the replacement spark plug. The sparkplug is sitting "higher" in the cylinder than the others (not as efficient).
It may even be a different sparkplug altogether in order to accommodate the adapter.

Add a silicone insulator gel (AutoZone $2) inside both boot ends of the sparkplug wires and re-seat them all.
