3. Note the position of the spark plug wires before removing the wires.
4. Twist the spark plug boot 1/2 turn before removing the boots.
5. Gently pry the heat shield up from the spark plugs using the J 38491 .
6. Remove the spark plug wires from the spark plugs.
7. Remove the spark plugs from the engine.
8. Hope this helps, as far as spark plugs on backside of of engine, it just depends. Some people rock the engine forward to get at rear plugs. Sometimes I crawl underneath see if easier to reach plugs? There can be safety issues working under a vehicle. Safety is your responsibility. Your local auto store should have whatever tools you need.

1. Disconnect the spark plug wire at each spark plug.

• • Twist each spark plug 1/2 turn.
  • Pull only on the boot in order to remove the wire from each spark plug.

1. Disconnect the spark plug wire from the ignition coil.

• • Twist each spark plug boot 1/2 turn.
  • Pull only on the boot in order to remove the wires from the ignition coil

Install the spark plug wires at the ignition coil.

Install the spark plug wire to each spark plug.

Inspect the wires for proper installation:

Repeat above procedure for all 8 cylinders.

1. • 1 Cool the engine before attempting to remove any spark plugs.
     
   • 2 Remove the spark plug wires located across the top of the Eclipse model's engine. The spark plug wires connected to the spark plugs are the flat circular ends. Grab the wire around the circle and twist to unlock the wire. Lift up on the wire to remove it from the engine. Some models with ignition coils above the spark plug may require you to unhook the wire from the ignition coil to remove the wire.
     
   • 3 Drop the socket with the extension and socket wrench attached into the cylinder well and on top of the spark plug. Turn the socket wrench to unscrew and pull the spark plug out of the engine.
     
   • 4 Spray silicone spray into the cylinder well and onto the new spark plug threads.
     
   • 5 Insert the new spark plug into the socket with the threads sticking out. Slide the socket into the cylinder well and gently turn the wrench to the right to thread the spark plug into the cylinder head.
     
   • 6 Use the tension tool to test the tension or torque of the new spark plug. Set the tension to the specifications listed on the spark plug package.
     
   • 7 Reattach the spark plug wire to the new spark plug.
     
   • 8 Continue this process with the other spark plugs. Be sure to only complete one spark plug replacement at a time.
     

Inspection

Inspect for the correct routing of the spark plug wires. Improper routing may cause cross-firing. Inspect each wire for any signs of cranks or splits in the wire. Inspect each plug wire boot for tearing, piercing, arcing, carbon tracking or a corroded terminal.
If there is any corrosion, carbon tracking or arcing indicated on a plug wire boot or terminal, both the plug wire and component it was connected to should be replaced.

4. If the engine was rotated for access, return the engine to the original position.
5. The remainder of the installation is the reverse order of removal.

There will be 6 spark plugs. 3 at the front of the car between the engine and the radiator. 3 on the other side of the engine close to the firewall. You can follow the spark plug wires to locate each plug. The engine is transverse mounted, or sideways. It can be difficult to plugs on this type of engine because of clearance problems. I use a special spark plug socket that is extra long. Instead of using a ratchet wrench, I use a 7/8 inch ratcheting box end wrench on the socket. The socket has a rubber insert to hold on to the plugs after they have been removed from the engine. Be careful when removing the spark plug wire. They get stuck on the plugs, and pulling on the wire will damage it. If you don't have a tool designed for removing spark plug wires, twist the boot, or the big end of the plug wire that slips over the end of the spark plug. Once is is loosened up, you can pull it off the spark plug. Pull on the boot, never the wire. Only remove one wire at a time to avoid getting the wires crossed. To install the plugs, get a 6 inch length of rubber vacuum hose that will fit tightly on the end of the spark plug. Use this as a handle to install the spark plug into the engine. Once the spark plug is threaded in to the engine, pull the hose off the end of the plug and use the socket and ratcheting wrench to finish tightening.

Here's how to remove the spark plugs.

1. Remove the engine sight shield, if necessary.
2. Disconnect the spark plug wire from the spark plug. • Twist each spark plug wire 1/2 turn. • Pull only on the boot in order to remove the wire from the plug.
3. Loosen the spark plug 1 or 2 turns.
4. Brush or air blast away any dirt from around the spark plug.
5. Remove the spark plug. If removing all the plug at one time, place each plug in a tray marked with the corresponding cylinder numbers.

Installation Procedure

1. Inspect the spark plug gap. Adjust the plug as needed. Specification
   Spark plug gap: 1.524 mm (0.060 in)
   
2. Hand start the spark plug.
3. Tighten the spark plug. Tighten • For used heads tighten the plug to 15 N·m (11 lb ft). • For new aluminum heads tighten the plug to 20 N·m (15 lb ft). • For new iron heads, tighten the plug to 30 N·m (22 lb ft).
   

The heat shield on the plug wires are there to keep the heat off the wires.I believe they are only on the rear ones.Yes they do come off.They need to be installed on the new ones.There are some special pliers that are for removing the wires but sometimes they ruin the wires.The best way to remove the plug wires is to grab and twist back and forth and out.What happens is the rubber part kind of sticks on the porcelin part of the plug and you have to twist it to break it loose.Hope this helps.Good luck.

There are no spark plug wires on the 2000-up Northstar engines. They use coil on plug design. First remove the engine service cover.(The Pretty plastic peice that has the Cadillac symbol on it) Then disconnect the coil connector which sits to the right of the coil and should just snap off by hand. Next If you remove the screws that holds the coil pack (8 screws) to the top of the cam covers, you will see 4 black round rubber boots that sit on top of the plugs. Pull the boots free to expose the plugs. The tops of the spark plugs sit directly underneath

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

Well first you will want to get the right size spark plug socket , the rigt sized one for your envoy and then next you will want to remove one spark plug wire at a time so you do not cross any of the wires or if you do you will mess up the timing for the envoy now how to remove a spark plug wire, look first at the plug wire and then gentky twist the wire on the end that goes over the spark plug and carefuly pull back but do not break the wire, next with an extention and the socket put the socket over the spark plug and turn the plug counter clock wise until you have removed the plug and then put the new spark plug in and place the spark plug wire back on the spark plug and just repeat the prosses on the rest,agin do them one at a time that is how I change spark plugs and wires and i have been doing it for years.
