Four bolts on that big plastic thing - 10mm, if I recall - and the cover over the engine comes off. Two are obvious, the other two are covered by coil assemblies. Not hard - though a tiny bit more work than older cars.

Gap plugs


spark plugs must be removed from the engine to ck or set the gap
you will need the correct size spark plug socket wrench (spark plug sockets are special as they have padding inside them to grip the plug after you unscrew them )

locate spark plugs on engine I believe your car has 4 of them

locate soft protection boot at end of wire and twist it 1/4 way around then back now grasp protection boot (NOT WIRE) and twist and pull away from spark plug till it seperates

wipe plug well out with clean rag (prevents dirt from falling into open hole)

put plug socket over over plug and remove CCW

locate emmisions sticker just infront of cooling fan and ck for plug gap

using plug gap tool slide wire of tool between the hammer and anvil on botton of plug (flat thing and curved thing )

if wire from tool slides thru with ease and even wiggles a bit
plug is in need of replacement

obtain new plug ck gap same method if new one is a one size fits all type you may need to use alignment tool part of gap checker tool (TEE looking thing) by sliding tee opening over hammer arm and gently bending down to tighten or away to loosten it

reinstall plug in engine torque to mfg specs(about 20to 30 ftlbs) and apply dilectric boot grease to boot protection sleeve and push down firmly over plug you;ll feel it snap on

do same for all spark plugs

How can i change my own spark plugs on my kia optima 2006


If it's a 4 cylinder then you have to remove the "coil pack" from the top of each spark plug. Should be a 10mm socket. then using a long reach spark plug socket, remove the spark plugs. Make sure to set the "gap" of the new ones before you install. Then re install the coil packs and secure them.

If it's a 6 Cylinder then remove the plug wires from the top of the plugs, then smae as above but you will probably use a spark lug socket and a short extension with the rachet, Once again be sure to "gap" the plugs before you install. best to do the plugs ONE AT A TIME, so that you don't mix up the wires.

I own a 2006 kia optima LX. I need to know the location of the spark plugs and the gap size.


Hello gray1139. My name is Roger and I will help. You did not say which engine was in your car so i looked up both. The 2.4 -4L.with a vin. of 3 or 6 and the 2.7L with a vin.of4 or 8. Both gap at (0.039 to 0.043 in.) The plugs are located in the middle of the valve covers. They are under the coil packs. Each plug has its own coil. They should be held in by a 10 mm headed bolt. Remove the bolt unplug the wire pack.Twist and pull up on the coil. Should yon need further help please just ask. Please rate the answer. Thank You for using Fix Ya. Roger

2004 KIA OPTIMA WON'T START AFTER SPARK PLUGS WERE CHANGES


HI. There are several areas of concern here. I will list them below. Check all areas stated in the list for faults.

Possible cuases:

1. Incorrect firing order set. On the 2.0, 2.4 and 2.7 engines. These engines are equipped with a distributor-less ignition system. This system incorporates a coil pack assembly, along with wire sets. In order for the assembly to fire correctly, the order of the wires must be set to the proper sequence. if not, the engine will not turn over, or start correctly. Make sure your firing order is correct, and make sure you have not placed a particular wire set into the wrong cylinder. I will post a picture of the correct firing order for your engine, below this list, shortly.


2. Incorrect spark plug gapping procedure. If the new spark plugs were gapped incorrectly, this will not allow for proper spark, thus, preventing optimal combustion, due to lack of fire. Check the spark plug gap using a wire gap gauge, and adjust if necessary. The gap should be 0.039-0.043 in. (1.0-1.1mm)

3. Failed coil pack assembly. This will be the worst case scenario. The coil pack supplies the necessary current that fuels each plug. The current is transferred, via wire sets.This will be the culprit if all the above areas are proven to be operational, and in good shape.

4. Failed wire sets. Replace the wire sets if faults are found at the connector at the ignition coil pack, or at the plug boot.



NOTE*
In order to provide the correct firing order for your engine, i will need the engine size and liter information, if possible. Please post this information, asap. Thanks..
