How to change spark plugs

You will need a 12 mm wrench and socket, a 10 mm socket , an extension and the socket for your spark plugs, and an intake plenum gasket. Start by pulling the positive cable from your battery. Next pull the intake cover off the top of the motor. On the drivers side you will see 3 coil packs or "cops" ( coil on plugs) those have two 10mm bolts, one on each side. Remove those , pull the coil, unscrew your spark plug with your socket, and replace.
On huge passenger side you will have to remove the upper intake arch (plenum) to get to the remaining three plugs. Repeat process from the drivers side. !!!!replace your intake gasket when you remove the upper plenum or you will have a vacuum leak.

How u change spark plugs

Hi there:

First I suggest purchase the spark plugs from your local auto parts dealer. Make sure to indicate the year, make and model of your vehicle to make sure you get the proper spark plugs. Locate the spark plug wires that run from the distributor cap to the cylinders on the left side of the engine. Use an 8 mm socket to remove the bolt that holds the coil pack on the cylinder, put the bolt in a safe place and pull the coil off. You only want to work on one spark plug at a time so you don't get the wires mixed up.

Insert the 3/8 or 5/16 inch hexagon socket and extension into the spark plug cavity and turn counterclockwise very carefully. Once the spark plug is free, bring it out of the cavity and put it to the side.
Place a new spark plug in the cavity threads pointing up and tighten until snug in a clockwise direction. Repeat for the other two spark plugs in this area.

Rear Spark Plugs
Position yourself so you can see the throttle body. There will be an Exhaust Gas Recirculation (EGR) valve on the front part of the plenum, which is right behind the throttle body.
Use a 10 mm socket to remove the two EGR valve bolts and nuts. Turn these in a counterclockwise direction and put them in a safe place. This will help release the EGR tube. If it does not release the tube, pull the tube to disconnect it.
Grab the gasket that is located between the two bolts, remove it, and put it to the side. Replace the gasket when you put things back together.
Move to the passenger side of the plenum and find the vacuum switch. Pull the hoses off and disconnect the electrical wiring by pulling it away from this area.
Find the eight bolts that hold the upper intake plenum on the back two cylinders and remove them in a counterclockwise direction. Grab the sides of the plenum and rotate up and towards the driver's side of the vehicle. This will give you access to the rear spark plugs. The gasket on the plenum is reusable unless it is damaged.
Use a 3/8 or 5/16 inch socket and extension to remove the spark plugs. Insert the socket and extension into the cavity and rotate in a counterclockwise direction. Be careful while removing and replacing the spark plugs as they are delicate and you don't want them to break, especially while in the spark plug cavity.
Replace with new spark plugs, with the thread side up. Put the plenum back in the reverse order.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

How do you access the rear spark plugs on a 2004 Sante Fe 6cyl?

You have to remove the intake plenum to access the spark plugs. That's the piece that sticks up and completely covers the back side when looking from the front. If you have fairly average car repair skills, it isn't all that hard but does take a lot longer than a normal spark plug change-out. If you remove the plenum and do this job yourself, you MUST replace the intake plenum gasket or you will end up with a bad vacuum leak. I strongly recommend you refer to a maintenance manual if you attempt this procedure. There is a lot of stuff attached to the plenum that has to be removed.

2000 Sportage: where is the spark plugs located on a 2000 Kia Sp...

They are under the black plastic cover that is in the middle of your valve cover gasket. Remove the intake hose from the aluminum intake plenum on top of the valve cover and the silencer box against the firewall. Remove all the connectors from the sensors which should be 2 on the plenum and the 2 large vacuum hoses on the plenum. Then remove the 3 12mm bolts from the plenum at the throttle body and remove the plenum. You can reuse the throttle body gasket at the plenum so don't destroy it. All the other bolts are 10mm and use a screwdriver to loosen the clamps on the hose. The sensors have clips that you need to remove with a small screwdriver, then disconnect them. Remove the bolts on the cover and the cover. Then remove the bolts holding the coil packs down. Do one plug at a time. 2 of them are connected to the 2 plug wires and 2 are underneath the 2 coil packs. The connectors on the coil packs are fragile so remove them carefully. Reverse the steps to reinstall the plenum, etc.

How do you change the spark plugs on a 6 cylider when 3 of the spark plugs are hidden?

You have to remove the plenum to get to them and have an extension to attach to the socket...Expect to have some bloody knuckles by the time you are all done. Don't forget to buy a new gasket to put the plenum back on.

The plenum is the silver or black colored thing on top of the engine. It covers most of the top of it. It is also known as the intake manifold.

How do i get the back 3 spark plugs out of the firewall side of the motor?

You have to remove the intake plenum, the plugs are under it...Just take you time and watch what you are doing.. If needed, go to library and look in a repair manual for the vehicle as to how to R&R intake plenum.. Is this a 2.5 liter or 2.7 liter?

The 2.5 liter is the one with the plenum removal necessary...2.7 liter just has the plugs in the rear head but up under the windshield cowl.

2.5 liter, Remove the air plenum on that one to get to the back plugs,and when you do you,ll need to replace the gasket for it,those are hard to get to,use a really good socket because those are close and if the socket slips there's plenty of things to bust a knuckle on ,it takes a while to do those ,but be sure and don't hit the plug on anything when your installing it,that will throw the gap off and it wont run right,take your time with it,good luck.

2.7 liter, you do not have to remove the plenum. If you look under the wiper cowl area on the back head you will see the 3 coils just like on the Front bank. Remove the coils and the plugs are underneath. you will need a spark plug socket, 3 in extension, and a 1 in extension to get these out because of the clearance. Your car is the same as any 2.7 from 2001 until 2006.

Good luck

Gettting the intake plenum off a 02 freelander

My 2002 Land Rover Freelander V6 thermostat crapped out as well and I decided to replace it myself.

The plenum is deceptive, but after 3 hours of looking and trying I finally got it off. Of course there are many hoses and electrical connections that need to be removed, but that's the easy part because you can see them all. The bolts that hold on the plenum are what your worried about and I will now tell you where they are. Read this and you should take about 30min to remove the plenum.

There are a total of 6 bolts to be removed that secure the intake plenum to the intake manifolds.

First remove the 4, 10mm large and obvious bolts at the top of the plenum. Now here is the tricky part, there are 2 bolts that are at the back of the plenum near the fire wall. As you are looking at the intake plenum from the front of the car, they are on the back side of the plenum near the fire wall on the passenger and driver side of the intake plenum.

Both bolts your looking for are 8mm bolts. If you remove a 10mm bolt, your removing the bolts that secure the rear spark plug coils.

The driver side rear intake plenum 8mm bolt is secured to the plenum itself. Fell with your hand about the back of the plenum on the right side for a lone bolt that is in the plenum with a metal tab that goes down to the back of the rear cylinder head. Remove the bolt that is attached to the intake plenum, not on the rear cylinder head

The passenger side one is a bit different. Feel on the back of the intake plenum about the passenger side for a metal support tab that comes down from the intake plenum and secures to the rear cylinder head. Where the support tab attaches to the head is a 8mm bolt that you remove.

Now here come the leap of faith. If you have the 4, 10mm obvious bolts removed and the 2, 8mm from the rear of the plenum removed, and if you can rock the plenum up and down about 2-3 inches,but it still feels like its attached to the intake manifolds in the middle of the engine, then you have removed all the bolts that secure the intake plenum to the engine. This is good.

The intake plenum is now being held on by the rear intake manifold by 3 O-ring gaskets. Push onto the back of the intake plenum near the firewall to expose a gap at the front of the intake plenum at the front intake manifold. Put 2-3 long flat screwdrivers into the gap or a small pry bar, and ever so gently but forcefully, apply prying force as to not damage the mating surface of the aluminum intake manifold, until the intake plenum pops off. It will just POP off.

Now that the intake plenum is popped off, take careful note of all the electrical plugs and hoses as to where they attach. You will not need any tools to disconnect the electrical plugs or hoses. To remove the hoses, push down the red ring with you fingers that the hose goes into and pull on the hose, it should come out very easily. The electrical connectors, push on the metal clip down and pull the connector loose. The electrical connectors only plug into their own plug, so you cant mess them up.

Tools you will need to replace the thermostat;

1. 8mm combo wrench. Make sure its not too long, shorter is better.
2. 10mm socket, shallow. 10mm combo wrench
3. 2-3 flat screwdrivers, for prying off the intake plenum
4. Ratchet wrench
5. 1 foot long worth of socket extensions. 2 6inch extensions will work as well
6. Universal socket joint
7. Angled needle nose pliers make it easier for hose clap removal, but straight needle nose pliers will work
8. Diagonal cutters to cut securing zip ties for the wiring harness

Take you time, once the plenum is off it goes pretty smooth after that. We removed just the forward intake manifold and that was more than enough clearance to remove the thermostat. You do not need to remove the fuel rail or spark plug coils from the manifold but you will need to disconnect the electrical connections to move the intake manifold out of the way.

Take pictures, there's a lot of hoses that go all over the place. The electrical connectors are only long enough to go where their supposed to go.

Then take that UK piece of **** to the dealer and trade it in for anything made in the USA or Japan. Changing a thermostat in any of those will only take 10 min and require 1 tool.
