1997 Chrysler Concorde 6 cyl Automatic

We have a 1997 Chrysler Concorde, and our roommate is proficient to do most all basic repairs on our car, but he has run into a snag. We need to replace the spark plugs, and he cant figure out how to remove them. I looked and may have found a partial answer. Do we need to remove the ignition coil assembly on this model before removing the plugs themselves. If so how is this done. If not what is the proper procedure

TIP: Always keep plugs in the order they were removed. Any plug that looks different from other plugs indicates a problem in that cylinder.

NOTE: For further diagnosis by spark plug condition SEE Ignition System/Spark Plug/Testing and Inspection/Procedures

CAUTION: Note routing of secondary ignition cables before removing. Failure to route cables properly may result in radio interference, ignition cross fire, or ignition short to ground.

REMOVAL

1. Spray compressed air around spark plug to prevent foreign material from entering combustion chamber.
2. Remove spark plug wire by grasping boot and turning 1/2 turn while pulling boot back in a steady motion.
3. Remove spark plug using socket with foam insert.

INSPECT FOR:

* Color of Deposits
* Excessive Deposits
* Electrode wear
* Cracked or Damaged Threads Or Insulator
* Worn or Bent Electrodes
* Damaged Gasket

INSTALLATION

1. Start plug in cylinder head by hand, to prevent cross threading.

CAUTION: Do not overtighten plugs, overtightening can distort plugs resulting in a changed gap.

2. Torque spark plugs to 20 ft-lbs (28 Nm) .
3. Install secondary ignition cables on spark plugs, (be sure connectors are pushed onto plug completely).

CAUTION: Always tighten spark plugs to the specified torque. Over tightening can distort the plug changing -- the plug gap. Over tightening can also damage the cylinder head.

NOTE: Spark plugs that have low mileage may be cleaned and reused if not otherwise defective, carbon or oil fouled. After cleaning, file the center electrode flat with a small flat point file or jewelers file. Adjust the gap between the electrodes to the dimension specified.

HIGH SPEED MISS CAUTION: When replacing spark plugs because of a high speed miss condition; avoid wide open throttle operation for approximately 80 km (50 miles) after installation of new plugs. This will allow deposit shifting in the combustion chamber to take place gradually and avoid splash fouling shortly after the plug change.

First of all thank you so much for your donation.From the information i have it look's like there just deep set plug's.I posted the replacement step's for you.
