Location of spark plugs in back of engine

I managed to get out all six spark plugs and replace 5 of them. I can't seem to find the hole for the last one. Is there a diagram that you might be able to show me for the location of the ones in the rear of engine?

How to replace spark plugs in a kia sorento


The 2006 KIA Sorento is a smaller SUV with a 3.5-liter V6 engine. This engine uses six spark plugs to run the engine properly. There will be three spark plugs on each side of the engine. All six spark plugs will need to be changed at the same time to ensure that all six are working equally. The spark plugs are in plain sight on the right and left side of the engine and have rubber wires connected to the top of each one.
  1. 1 Insert the edge of the spark-plug gapping tool under the meal arm in the center of the one of the new spark plugs and turn the gapper until the number .038 is in the center of the metal arm. Repeat this for all other new spark plugs.
  2. 2 Open the hood of the 2006 KIA Sorento and remove a rubber wire from one of the spark plugs. Use the ratchet and spark-plug socket to remove that spark plug from the engine.
  3. 3 Insert the new spark plug into the hole where the old plug was. Hand-tighten the new spark plug until you are certain it is seated properly, then tighten it further using the ratchet and spark-plug socket. Replace the rubber wire to the top of the new spark plug.
  4. 4 Repeat for all other new spark plugs. Once you have replaced all six spark plugs and replace the rubber wires to the tops of them, close the hood.

O-ring seal for spark plug are leaking. Located under valve cover.

How to change the spark plugs on the 3.0


1. Pull the hood release lever located under the dashboard.

2. Walk around to the front of the car, reach under the hood, find the latch and squeeze it. Open the hood.

3. Find the spark plugs, located in a row along one side of the engine (on an in-line four-cylinder engine) and attached to thick wires, called spark plug wires. Cars with V-shaped engines (which can have four, six or eight cylinders) will have spark plugs and spark plug wires on both sides of the engine.

4. Change one spark plug at a time, always putting the plug wire back on before changing the next spark plug.

5. Pull off one spark plug wire where it attaches to the plug. There is a little rubber boot at the plug end of the wire; pull on this part. Pulling higher up on the wire can damage the spark plug wire and cause it to separate.

6. Blow or wipe away any dirt or debris around the spark plug. You do not want anything to fall into the cylinder while the spark plug is out.

7. With the spark plug socket and a ratchet, remove the spark plug by turning it in a counterclockwise direction. You may need an extension for your ratchet if the spark plugs are deep-set or not directly accessible. Ratchets with flexible heads are especially helpful for hard-to-reach spark plugs.

8. Check the spark plug to make sure it needs replacing. A good spark plug should be lightly coated with greyish brown deposits. If heavy deposits are present, if the spark plug is black or if the electrode or core nose are damaged, the plug needs to be replaced.

How do u change the spark plugs on a 1994 toyota camry


Start with a cool/cold engine.

Four cylinder: Remove spark plug wire boots (four in a row on top of the engine). DO NOT PULL ON THE WIRE only the rubber top. Make sure the wires are numbered, if not, number them. They MUST go back to the same hole they came out of after the new plugs are installed. Remove the spark plugs with a 16mm spark plug wrench. Install new plugs (any auto parts store can tell you what your options are here): Start threading the new plugs by hand so you don't cross thread the engine head by accident. Then complete tightening them gently. Spark plugs are supposed to be tightened to a specific torque: 13ftlbs in this case. If you choose to not use a torque wrench do not overtighten the plugs. Reinstall boots securely.

6-Cylinder: Remove engine cover, if present. Disconnect the six connectors on each of the ignition coils. Remove each of the six ignition coil bolts and then remove the coils by pulling straight up -- arrange them so that you know which goes back where. Remove and install the six plugs as described above. Reinstall the ignition coils with their bolts (torque: 69 in-lbs), then wires. Replace the cover.

#8 coil pac, cylinder misfire...Need diagram The mechanic says I need a coil pack and spark plug replacement for the #8 ...Need diagram to figure out which one it is. it is


The #8 coil and spark plug are located on the drivers side rear of the engine. You will need a 7mm socket to remove the bolt that holds the coil down. After the bolt is out, pull the coil upwards and remove. Next you will need a 9/16" spark plug socket to remove the spark plug which is located in the hole that the coil came out of. The spark plugs in a 5.4L engine are sometimes frozen into the engine. If it is very hard to turn the plug, try spraying some WD-40 down the hole onto the plug and let it soak in for a while. Do not try to force the plug to turn, it will break and a special plug extractor will be needed to remove it.
Hope this helps you!

Distrbutor to spark plug wiring


Hey there janandshane,

I've got a 91 Wrangler, lots of fun. Here's your info.

Viewed from above, front of vehicle on the right side, cylinder locations are:
6 5 4 3 2 1 for a six cylinder and 4 3 2 1 for a four Cylinder

The firing order is:
1 5 3 6 2 4 for the six and 1 3 4 2 for the four.

The distributor rotation is clockwise.

To find Top dead center (for wire to cylinder #1 on distributor), look for and line up the timing marks on the crankshaft (front of the engine).

Or, pull the #1 spark plug, stuff the hole with a cork or a rag. Slowly crank the engine until the cork pops out.

Pull the distributor off. The rotor is pointing where the plug for cylinder #1 should go. The rest of the wires go in the firing order clockwise.

That about covers it.

Remember: Good things come to those who rate. How about a nice FixYa?
