Changing spark plugs in any car

the best method is one at a time.pull the wire by the boot and remove.then remove other end in same fashion. measure the length of the old wire the the replacement and install making sure that the boots are well seated, you will normally hear a click or feel the boot seat.continue in this fashion until all wires are replaced,then proceed to change plugs one by one making sure that the air gap is to specifications.
do not overtighten plugs ,snug is fine.

change one spark wire at a time on the distributor.buy new set of spark plugs wires remove them from box.match old wires with new wires to use the correct length to each cylinder.now if you need to change distributor cap.mark location distributor cap.number tag plug wires on the distributor cap so you can remove plug wires on distributor cap so you can replace cap and rotor and put wires back on the distributor cap in correct place.remember change one plug wire at a time so you wont get confuse.

· Open the hood and remove the bolts that hold the engine cover in place, if your Dodge comes with an engine cover (depending on model and year). If so equipped, pull the cover off the engine.

· 2

Grab a spark plug wire by the base of the wire and pull the wire up and out of the engine. (You may need to wiggle it back and forth while pulling up on it to get it out of the engine.)

· 3

Trace the wire back to the power distributor and pull the spark plug wire off the distributor. Make a note of the plug orientation.

· 4

Install the new plug wire in the place of the removed one. Match the new wire with the old one to make sure they have the same size. Press the plug wire over the distributor electrode and onto the spark plug firmly, so that the ends are secure. Installation is the reverse of removal procedure.

· 5

Repeat the above procedure for all the other spark plug wires. It is best to change all the spark plug wires at the same time.

remove the bettery on the left side of car on the right side of car remove washer bottle remove spark plug wires and take of your spark plugs ( not an easy process hard to get to frame rail in the way)

Hi Glloyd806

the spark plug gap is .054
This is at best difficult and if not done right can destroy your heads ( about $2700.00). My advice is to have the dealership take the risk. However, If you decide to change the spark plugs yourself you'll need to know a few critical things first.
The 5.4L has aluminium heads, there is a design flaw in that the thread depth is to shallow, only 4 or 5 threads. because of this it is EXTREMELY IMPORTANT to apply anti-sieze on the threads of each spark plug and torque the plugs to NO MORE THAN 14 LBS. Also, if the plugs have been improperly changed before, it is to late, and you will rip the threads out when removing the old plugs.
Still wanting to do it yourself? OK here is how it is done;
Each spark plug has it's own coil, you will need a 8mm socket to remove the retaining bolt. Then disconect the coil wires on the coil. pull out the coil assembly (coil and boot). they may be stuck a little so you may need to wiggle it out. Now you are ready to remove the spark plug. You will need a THIN WALLED 5/8in spark plug socket, at least one extension, and on the #3,4,7, and 8 spark plugs you'll need a universal joint. the holes that the spark plugs are in are machined very thght and I found that I needed to try several different sockets before I found one that would fit inside the hole. Remove the old plug. apply anti-sieze on the threads of the new plug and install. DON'T CROSS THREAD, THERE IS ON SECOND CHANCE! TIP.. replace the old rubber boot with a new one and apply a liberal amount of spark plug moisture protectant gel inside the boot, spark plug end, this will save you from spark plug mis-fire due to moisture in the future. Place the new boot back on the coil and place the coil/boot back into the spark plug hole, it may need some wiggeling. Replace the coil retaining bolt (anti-sieze), reconnect the coil wires. Now do this 7 more times.

In all honesty, take it to a Mechanic, because this is a real pain in the....

Best of luck, and I'm not responsible for any damages you do :(
