 Subject: Spark Plug Installation
IP: Logged
Message:
I've worked on cars for many years, but have never replaced plugs
with individual, attached coils. I have a 2001, 4.7 liter. Can
someone provide me step-by-step directions? What about
antisieze and torque specs?
Any help is greatly appreciated

Spark plugs are easy to change. You need to remove the air cleaner box where it is attached to the throttle body. there are two pipes that run across the top of the engine. They are water pipes for the heater. They are held in place with a plastic mount that just clips in place.If you look carefully you can see that it unclips on one side.Open up the clip and you will be able to move the hoses/pipe over so you can access the spark plug under the hose/pipe. The coils have one nut that holds them in place. Remove the plug connection to the coil and then the nut, pull up on the coil and remove it. Use an air hose to blow out the hole where the spark plug is. Remove the spark plug. Gap the new plug at 40 thousands. You need to use some antisieze on the threads and some silicone grease inside the spark plug boot. Check to make sure the O ring on the coil is not damaged.torque the plugs to 20 ft pounds. Do not over tighten the plugs it will make them very hard to remove the next time and can also damage the threads.Reinstall the coil/spark plug boot and put the nut that holds the coil in place back on. Snug the nut down be careful not to over tighten and brake the plastic on the coil. You are done with one plug now do the other 7. MAKE SURE YOU USE THE SAME TYPE PLUG THAT IT CAME WITH. DO NOT USE A PLATINUM PLUG THE ORIGINAL PLUGS ARE COPPER CLAD TO DISSIPATE HEAT.You MAY GET SOME DETONATION IF YOU USE SOME THING OTHER THAT A COPPER CLAD PLUG. I ALWAYS USE THE CHAMPION PLUGS THEY WORK GOOD IN THE 4.7. If you need any more help or get stuck email me and I can help. I have done 3 plug changes on my 02 Dakota quad cab 4x4 with the 4.7. Hope this helps.

Jim -- thanks a bunch for the detailed instructions. Sounds pretty
straight forward. Before I start, I have to get a new torque wrench
since mine was "borrowed".
Also thanks for the advice on plug type. Are those Champions
#439?

Jim - I finally got around to changing the plugs today. It took me
about an hour. You were right -- EASY job. I can't believe how
much smoother it is idling now.
Thanks again for your EXCELLENT instructions.
