    I have tried to purchase a repair manual. I was told the automotive makers do not make them available to the public anymore.

    I have the same problem and cant seem to get to my back 3 spark plugs. I need to know how to remove the black manifold on top of the engine. Looks like it is plastic. I have loosened each bolt and it will only move an inch, how do I move it more?

How many spark plugs are in a 2005 Kia Sedona


There are six plugs in the Sedona. The motor is turned 90 degrees from which way we are accustomed to seeing one in a vehicle..
First remove the six bolts (10mm) that hold the engine cover on. You also have to remove the oil cap to take this cover off.
The front three plugs and their corresponding coils are in the front and fairly accessible as you can follow the spark plug wires to them. It is best to disconnect the battery before doing this work.

You will have to remove the three corresponding coils to the front three sparkplugs. You use a 16mm spark plug socket to remove the spark plugs.

The back three plugs are under the intake manifold cover. This is a difficult and awkward removal to get the cover off, because the back bolts are very difficult to access. Please watch the video to follow the details to get it off. The next three sparkplugs are under this cover.

This video was a good example what to do with the plug and coil once removed for maintenance.

And, another girl mechanic!

How To Change The Spark Plugs On A 2002-2005 Kia Sedona 3.5 Liter


You'll need to remove the oil cap and the 6 bolts holding on the engine cover. The front 3 spark plugs are pretty easy to replace. You'll need to unplug the spark plug wire from the coil and disconnect the electrical connector. Unbolt the 2 10mm bolts holding the coil to the valve cover. Twist the coil and boot back and forth and pull it out of the cylinder head. The spark plug is down in the head, you'll need at least a 6 inch extension with a 5/8" spark plug socket, a telescopic magnet will help get the spark plug out of the head. The back 3 spark plugs involve removing the upper intake and throttle body, unbolt the bracket to the throttle body, and the bracket bolted to the upper intake manifold. on the back side of the engine. Remove the tubing from the throttle body to the air cleaner box. Unbolt anything else bolted to the upper intake. Unplug electrical connectors to the throttle body and any other electrical connectors on the upper intake and remove the upper intake bolts. And move the upper intake out of the way, there are only spark plug wires on the back 3 plugs. Twist and turn each boot to aid in removing the boot from the plug. I would get a new upper intake gasket and consider replacing the wires at this time also. There are actually only 3 spark plug wires, so for what is involved to get to them, I would replace them. I have found alot of the wires will arc to the upper intake manifold.

Replacing spark plugs and coils on Mazda Tribute V6


Here are DIY step by step instructions for replacing the spark plugs and / or coils in a Mazda Tribute V6 (based on a 2001 Tribute).

This is a lengthy procedure, but don't be frightened, it works...I have done it a few times. This will save you a few hundred $$$ if you do it yourself. Make sure to read all of these instructions, preferably while looking at your engine, before you get started. You will need 2-3 hours to do this job.

NOTE 1: IF YOU HAVE A SPECIFIC ISSUE WITH CYLINDERS/COILS 4, 5, OR 6, YOU ARE IN LUCK, YOU ONLY HAVE TO REMOVE A PLASTIC ENGINE COVER. IF YOUR ISSUE IS WITH CYLINDERS/COILS 1, 2 OR 3, OR YOU ARE CHANGING ALL OF THE SPARK PLUGS, YOU WILL HAVE TO REMOVE THE INTAKE MANIFOLD. THESE INSTRUCTIONS COVER CHANGING ALL OF THE SPARK PLUGS AND CAN BE USED TO REPLACE ANY OF THE COILS.

NOTE 2: IF YOU ARE THINKING OF REPLACING YOUR SPARKPLUGS BECAUSE YOUR ENGINE IS RUNNING ROUGH, PLEASE DO YOURSELF A FAVOR AND GET THE ENGINE SCANNED FIRST TO MAKE SURE THAT A COIL IS NOT THE ISSUE. YOU CAN REPLACE YOUR PLUGS AND BAD COILS AT THE SAME TIME WITH THIS PROCEDURE. YOU WILL BE UPSET IF YOU DO THIS WORK TO REPLACE ONLY YOUR SPARKPLUGS, THEN YOU FIND OUT AFTERWARDS THAT A COIL WAS BAD AND YOU HAVE TO DO IT AGAIN LIKE I DID.

1. Tools: Pliers, ratchet wrench, ratchet wrench socket extension, 8 mm socket, 10 mm socket, Spark plug socket, flat head screw driver, plastic zip tie, plastic cup or bowl. Not necessary, but very helpful: Magnet on an antenna to pick up dropped nuts/bolts.

2. All directions are given from a point of reference as if standing in front of the car, except for removing the coils and plugs from firewall (back) side of the engine.

3. Using flat head screwdriver, loosen band clamp on large rubber air intake hose where it connects to the intake manifold on the right side of the engine. Slowly work rubber intake hose off of intake manifold.

4. Unplug wires from back side of air idler valve - small unpainted metal part mounted on top of air intake on manifold (close to where the air intake hose connects to intake manifold).

5. Disconnect small rubber hose from top of the ERG valve (black metal disk near back right side of manifold.

6. Remove the two bolts that hold ERG valve to manifold bracket. Use the 10 mm socket and ratchet to remove these. If you are trying to remove the 8 mm bolts, you are removing the wrong bracket. Be careful, there is a gasket between the manifold and the ERG valve, make sure it does not fall out when removing bolts. Place bolts and gasket in cup.

7. There is a small plastic sensor just to the left of the ERG valve towards the back of the engine. If you look at how the sensor is attached to the manifold, you will see that the back left side bolt that holds this sensor, also connects the intake manifold to a plastic wiring harness at the firewall. You will need to remove the 8 mm nut from this bolt to free up the intake manifold in a later step. Now remove 8 mm bolt from other side of sensor. Might need the socket extension to remove these. Place nut and bolt in cup.

8. Unplug wires from the back of the sensor discussed in the previous step (7).

9. There are 3 hoses of different sizes plugged into the back of the manifold. Unplug all three hoses from manifold. Remove zip ties if needed to slide hoses off. Left hose may have a compression clamp, use pliers to loosen clamp while sliding hose off.

10 There are two large black plastic wiring connectors supported by the back left side of the manifold. They are supported by plastic clips with plastic barbs. Use the flat head screw driver to pry off the support clips from the manifold - don't worry, you won't break them. You will be able to plug them back in later.

11. There are still a few things attached to the intake manifold, but there will be enough flexibility now to lift up the manifold and replace the spark plugs.

12. Remove the plastic engine cover - there are three 8 mm nuts to remove. You will need the socket extension. One the nuts are removed, you will have to wiggle the cover off especially on right side. Place nuts in cup.

13. The plastic intake manifold on top of the engine is now exposed. If you look down at the front side of the engine, you will see the coils for cylinders 4, 5 and 6 (going from left to right). The tops of the coils will probably say "Motorcraft" on them. Also, there are two cables attached to the top of the manifold - leave them alone.

14. There are 8 bolts that hold the intake manifold down. The bolts are located in two rows of 4 across the top of the manifold. Loosen them all using the 8 mm socket with extension. Note: these bolts do not come completely out when fully loosened.

15. Slowly work the intake manifold loose by lifting up on each side. NOTE: Work the manifold off of the bolt discussed in step 7 (back right side of manifold), NOTE: Work slowly watching for anything that might be hanging up. You should eventually be able to get about 4" of clearance between the back right side of the manifold and engine, and 8-10" of clearance on the back left side. Move around to the passenger side to help lift off the manifold. While working on the back side plugs, you will stand on the passenger side of the car.

16. Once you are able to lift up the manifold, get a cup, block of wood, anything suitable approx. 5" tall to prop up the manifold (place under center of manifold). This will keep the manifold off your hands while you are working.

17. The three coils on the back side of the engine are now visible if you are standing on the passenger side of the car (cylinders 1, 2 and 3) Cylinder 1 is closest to you - passenger side, cylinder 3 is furthest from you - driver side.

18. Each coil has one 8 mm bolt holding it down. Take the 8 mm socket and ratchet and remove the bolts from the 3 coils on the back side of the engine. Place bolts in cup.

19. Lift each coil away from engine (do not pull on wires plugged into the coil). Pull each coil's silicon rubber tube out of spark plug hole, bend tube to get it out without pulling on the coil wiring. Leave coils plugged in and lay them to the side. NOTE: If you are looking to replace a coil (or coils) simply unplug the coil wires from the old coil, and plug into new coil at this stage.

20. Using sparkplug socket and socket extension, remove each of the back 3 spark plugs.

21. Install the new spark plugs (gap them first if they are gap type).

22. Slide each coil rubber tube back into sparkplug hole and bolt down coil (8 mm bolt). Congratulations! The hard part is over with!

23. Make sure the rectangular intake port gaskets are clean on the engine (before lowering the intake manifold back down).

24. Slowly work the intake manifold back down to the top of the engine - make sure that the manifold is back on the bold discussed in step 7, and that nothing is binding.

25. Bolt the manifold back down (eight bolts, 8 mm, still attached to the manifold). Use 8 mm socket with extension. Gradually tighten the bolts going from bolt to bolt until they are all tight (don't fully tighten one bolt first).

26. Remove coils and spark plugs on front side of engine. Replace spark plugs and re-install coils. Same procedure as back side of engine, but much easier. Replace coil(s) if desired.

27. Re-install the two plastic wiring connector support clips to the left side of the manifold - push barbed clips into manifold.

28. Reconnect 3 hoses to back side of manifold. Place new plastic zip tie on hose that had zip tie.

29. Reinstall plastic sensor on back right side of manifold (8 mm nut and 8 mm bolt).

30. Plug in wires back into back side of plastic sensor.

31. Reinstall 10 mm bolts and gasket on ERG valve and tighten to manifold.

32. Reconnect small rubber hose to top of ERG valve.

33. Reconnect large air intake hose to intake manifold and tighten hose clamp using flathead screwdriver.

34. Plug wires back into back of idle air control valve (this was uplugged in step 4).

35. Leave the plastic engine cover off for now. Check all around the manifold and make sure everything is reconnected.

36. Start engine - should start and run normally (or better). If not, go to trouble shooting at the end.

37. Reinstall plastic engine cover (three 8 mm nuts). Make sure engine is not running when reinstalling plastic cover.

TROUBLE SHOOTING: If engine light comes on (and wasn't on before changing plugs), or if engine runs rough, stop engine and double check that all wires and hoses are plugged back in. If you find wires or hose left disconnected, reconnect them. Disconnect car battery for a few minutes then reconnect (to clear out engine alarm). Restart car, engine should run well, engine light should be cleared.

How do change spark plugs on a 1998 xj8


Remove plastic cover over the engine ( three screws).
You then have access to the front three spark plugs (cylinders 1,3,5) remove the nut which holds down the independant coils and remove the spark plugs, fit new spark plugs and fit coils on the three front cylinders.
Now it gets a little tricky, you will only be able to access number 2 back cylinder so you have to remove the induction manifold (12 bolts I think) to access the back three cylinders (2,3,6,) properly.
Then proceed as with the front three spark plugs, refit manifold and plastic cover,

Change sparks plugs on 06 hyundai sonata v6


You didn't specify whether you have the (4) cylinder or the (6) cylinder engine..... I have a 2004 Hyundai Sonata 2.4L 4 cylinder and I just changed the spark plugs in it. I believe that the 2005 2.4L engine is the same. To locate and change the (4) spark plugs on a 2004 Hyundai 2.4L 4 cylinder engine: Remove the (4) 12mm bolts from the decorative plastic engine cover. Remove plastic cover from engine and place it off to the side out of your way. Standing in front of the car, the (4) spark plugs are located laterally (left to right) in the recessed area underneath where the plastic engine cover was removed. Note: This engine has (2) coils....They are located above spark plugs number (2) and (3) from left to right. Starting with the fist spark plug on the left: Remove the spark plug cable by pulling straight up on the insulated connector. Using a spark plug socket, remove the old spark plug and install a new one in it's place. To access the second spark plug from the left, remove the electrical connector and the spark plug cable wire from coil number (1) and then remove the (2) 12mm bolts that secure the coil to the engine. Spark plug number (2) is located directly under the coil. Lift the coil straight up removing the insulated connector from spark plug number (2). Using a spark plug socket, remove old spark and install a new one in it's place. Repeat same procedures for spark plugs number (3) and (4). Note: If you have the (6) cylinder engine, the front (3) sparks pluge are readilly accessible but in order to access the (3) rear spark plugs, you will have to remove the intake manifold

Changing back spark plugs underneath engine cover


I'm fairly certain those motors require the upper intake manifold be removed to gain access to the rear spark plugs. You might be better off bringing it to a qualified technician as it gets fairly involved. If i remember correctly it's about a 2 hour job and requires a few gaskets.
