This requires a special plug boot removal tool so you don't ruin the plug wires, any auto parts store will have one, about $8

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.

Location of Spark plugs on Engine block?


The plugs arent in the block, they're in the cylinder heads. Follow the spark plug wires to them.

How do you replace spark plugs.


One spark plug at a time. Use a 3/8 extension and a spark plug socket, the socket should have a piece of rubber in it to hold the spark plug in it. Remove the spark plug wire to gain access to the plug, then using the socket and rachet with the extension, turning to the left untill spark plug is all the way out. Looking at a spark plug can tell you several things about each cylinder they come from, so get a manual for your car, anyways replace new spark plug in the socket, be sure to double check the right gap, then replace by turning to the right/clockwise direction untill it is snug in the hole. Do not over tighten or under tighten. Replace the sparkplug wire and move to next plug. Good luck

Easiest access to replace #1,3 ,5 spark plugs on 3.4 lit v-6?


There really is not easy access. You will have to climb on the car motor and follow the wires down to the plugs. Use a 3/8" socket with a spark plug boot and swivel. It will make things easier.

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 change spark plugs and coil connector wires on 2000 Ford Crown Victoria with 4.6 engine. First time on this type of system.


Each coil mounts on top of the spark plug and is bolted down to the intake manifold with a 8mm bolt. You'll need to unplug the electrical connector to the coil, remove the 8mm bolt and pull the coil and boot up off the plug and out of the motor. You'll need a 5/8 inch spark plug socket, a ratchet and a 6 inch extension. Also a telescoping magnet with help getting the plug up out of the hole.

Replace Spark Plugs


What size engine have your behicle?

2.2L Engine
  1. Remove the ignition coil housing.
    NOTE Remove any water and debris from the spark plug holes before spark plug removal with compressed air. Remove the spark plugs with a spark plug socket.
  2. Inspect the spark plugs.
To install:
  1. Gap the spark plug, using round wire type spark plug gap gauge. Adjust the spark plug gap to 0.045 in. (1.14mm).
    WARNING DO NOT coat the spark plugs with anti seize compound. Over torquing could occur and damage to the cylinder head threads may result.
  2. Install the spark plugs with a spark plug socket. Tighten to 15 ft. lbs. (20 Nm).
  3. Install the ignition coil housing.


2.4L Engine
The spark plugs on this engine are located under the ignition coil and module assembly. To gain access to the spark plugs, the coil and module assembly must be removed. On the 2.4L (VIN T) engines, the spark plugs are platinum and require replacement every 100,000 miles (160,900 km) or 60 months which ever comes first.

  1. Disconnect the negative battery cable.
  2. Remove the 4 bolts retaining the Electronic Ignition (EI) coil/module/cover assembly (depending upon vehicle application), then detach the electrical connector. Remove the assembly by pulling it straight up away from the engine.

    Fig. To remove the cover, unfasten the four bolts, then pull the assembly straight up from the engine
  3. If the connector(s) sticks to the spark plug, use spark plug connector removing tool J-36011 or equivalent, and a twisting motion to detach the connector(s) from the plugs.
  4. Clean any dirt away from the spark plug recess area.
  5. Remove the spark plug using the proper size socket, extensions and universal joints, as necessary. Hold the socket or the extension close to the plug with your free hand, as this will help lessen the possibility of applying a shear force which might snap the plug in half.
To install:
  1. Lubricate the threads lightly with an anti-seize compound, then start the four spark plugs by hand. Tighten the plugs to 14 ft. lbs. (19 Nm).
  2. If removed, install any the plug boot connectors that may have stuck to a spark plug to the EI assembly.
    NOTE Check to make sure the spring terminal is inside the boot.
  3. Install the EI coil/module/cover assembly to the engine, while carefully aligning the boots with the spark plug terminals, by pushing the assembly straight down.
  4. Apply Loctite®thread locking compound, or equivalent to the cover bolts. Install the bolts and tighten to 16 ft. lbs. (22 Nm).
  5. If removed, engage the ignition cover electrical connectors.
  6. Connect the negative battery cable.

I really hope helped with this (remember rated this help) Good luck.

Plug replace


This is a outstanding question!!! The plugs or wires are not visible from the top or sides of the moter. You just can't see em'!!! You have to remove the large black plastic air intake. Then remove the intake manafold(not too hard to do) to access the spark plugs and wires.
Also: After removing all the black plastic air intake stuff, you'll have to remove the coil pack (long black plastic thing that says "Ecotek" on top). The coil pack is removed by disconnecting the wire connector on the driver's side end and then removing four bolts. To lift off the coil pack, you'll have to pull upwards firmly and evenly from both sides, because the spark plug boots or wires are holding onto the spark plugs as well as the coil. With the coil pack removed, look down into the silver channels - there's the plugs. To remove, you'll need a plug socket head and a socket wrench with long extension. To replace the plugs, I use an extra or old spark plug boot to hold the plug and get it started turning into the engine threads. Good Luck!
