Where r the spark plugs located?

On the internet Google it

Hi Carol,here's a link on how to replace your spark plugs.

Locate the spark plug wires in the Cherokee cylinder head. In the 4.0 liter engine, the spark plugs are below the coil rail assembly. On the 4.7 liter engine, the spark plugs are located under each corresponding engine coil.

they are located on the side of the engine under the ignition coil rail. see pic of coil rail below

Here's a link that will help you. I've included the info that you need to locate the plugs below. Good luck!

To gain access to the spark plugs and spark plug wires do the following. In a 2.4 liter engine, remove the ignition coil and module assembly from the top of the engine to gain access. In this Alero model's engine, the spark plugs run down the center of the engine. In a 3.1 liter engine, remove the air cleaner to gain access. The spark plugs are located next to the engine oil reservoir. For a 3.4 liter engine, remove the windshield wiper module cover and rotate the engine for service access. For a 2.2 liter engine, the spark plug wires are located across the top of the engine and require no components to be removed for access to the spark plugs.

Your spark plugs can be located in 2 different locations.
1 if your engine is sitting front to back of the vehicle your plugs will be located on the drivers side and the passengers side of the vehicle.
2 if your engine is set from one wheel well to the other than your spark plugs will be located on the front of the engine ( front towards the bumper/grill.) and next to the firewall.

4.6L, 5.4L & 6.8L Engines

1. Disconnect the negative battery cable.
   
2. Remove the coil on plugs as outlined under Ignition Coil in this section.
   
3. 
   
4. Remove the spark plugs.
   
5. Inspect the spark plugs
   
6. Adjust the spark plug gap as necessary. Proper gap is 0.52–0.56 in. (1.32–1.42mm).
   
7. 
   

installation.

1. Install the spark plugs and tighten them to 13 ft. lbs. (18 Nm) for 4.6L and 5.4L SOHC engines. For 5.4L DOHC and 6.8L engines, tighten the spark plugs to 15 ft. lbs. (20 Nm).
   
2. Install the coil on plugs.
   
3. Connect the negative battery cable.
   

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

The 2003 Kia Sorento with V6 has the spark plugs located under black plastic covers in the center channel of each cylinder head. Several brackets, cables, and hoses must be moved out of the way to access them. The manifold air intake tube needs to be removed on the right bank.
The left cylinder bank has coil-on-plug assemblies while the right bank has more conventional spark plug caps with sealing assemblies. The coil-packs are held with two 10mm bolts each and are difficult to get to. Use universal-joint sockets and an extension.

To change the sparks on a 2005 4.7L Dodge Dakota you will need the following:

• Spark plug socket
• Ratchet
• Torque wrench
• Extension
• Flat-tip screwdriver
• Make sure the truck is cold!!!

Note you will have to remove the air intake located at the top of the engine, and will have to move some of the coolant lines out of the way.

At the top of the engine there are 4 sparks on each side. The coils are held in place with a 10mm bolt. Undo the 10mm bolt and unclip the coil. Next pull out the coil.

Insert the socket, with extension into the spark plug hole.

Remove spark plug.

Check the gap on new spark plug, it should match stock.

tighten to approximately 25ft.lbs. (check spark-plug packaging for exact torque requirements).

repeat this process with all other sparks.

be sure that no dirt gets into the spark plug holes.
