Spark Plug Replace question

My 2009 V-6 spark plug coils are not like previous years. Each has a bolt (not a nut) which remains captive, and I can only lift the coil about an inch, until it hits the bolt. The bolt spins (loose) but does not come out. How do I remove the coils?

Re: Spark Plug Replace question

sounds like you didn't loosen the bolt all the way, my 07 also had two bolts on each plug boot

Re: Spark Plug Replace question

You have a V8, mine is a V6, which is different, with only one bolt per coil. The bolt is loosened all the way, until it spins, but does not come out.

Re: Spark Plug Replace question

tell me if what I said sounds like it makes sense, or if it makes more sense that they'd make bolts that spin and come out 2"

Re: Spark Plug Replace question

What you said makes sense. It does sound like I did not loosen the bolt all the way, and it makes no sense that the bolt will not come out after loosening it all the way. But this is what I have, and this is why I am asking for help. I am looking for someone who has replaced spark plugs on a 2009 V6, to help explain what I am missing.

Re: Spark Plug Replace question

3.7-L V6 (2005-2010)
(standard on Laredo)

Removing plugs - 3.7L engine Each individual spark plug is located under each ignition coil. Each individual ignition coil must be removed to gain access to each spark plug. The coil fits into machined holes in the cylinder head. A mounting stud/nut secures each coil to the top of the intake manifold. The bottom of the coil is equipped with a rubber boot to seal the spark plug to the coil. Inside each rubber boot is a spring. The spring is used for a mechanical contact between the coil and the top of the spark plug. These rubber boots and springs are a permanent part of the coil and are not serviced separately. An o-ring is used to seal the coil at the opening into the cylinder head.
1. Remove necessary air filter tubing at throttle body.
2. Prior to removing ignition coil, spray compressed air around coil base at cylinder head.
3. Depending on which coil is being removed, the throttle body air intake tube or intake box may need to be removed to gain access to coil.
4. Disconnect electrical connector from coil by pushing downward on release lock on top of connector and pull connector from coil.
5. Clean area at base of coil with compressed air before removal.
6. Remove coil mounting nut from mounting stud.
7. Carefully pull up coil from cylinder head opening with a slight twisting action.
8. Remove coil from vehicle.
9. Prior to removing spark plug, spray compressed air into cylinder head opening. This will help prevent foreign material from entering combustion chamber.
10. Remove spark plug from cylinder head using a quality socket with a rubber or foam insert. Also check condition of ignition coil o-ring and replace as necessary.

Re: Spark Plug Replace question

nstalling plugs - 3.7L engine Special care should be taken when installing spark plugs into the cylinder head spark plug wells. Be sure the plugs do not drop into the plug wells as electrodes can be damaged.
Always tighten spark plugs to the specified torque. Over tightening can cause distortion resulting in a change in the spark plug gap or a cracked porcelain insulator.
1. Start the spark plug into the cylinder head by hand to avoid cross threading.
2. Tighten spark plugs to 20 Ft. lbs. torque.
3. Before installing ignition coil(s), check condition of coil o-ring and replace as necessary. To aid in coil installation, apply silicone to coil o-ring.
4. Using compressed air, blow out any dirt or contaminants from around top of spark plug.
5. Position ignition coil into cylinder head opening and push onto spark plug. Do this while guiding coil base over mounting stud.
6. Install coil mounting stud nut.
7. Connect electrical connector to coil by snapping into position.
8. If necessary, install throttle body air tube.

Re: Spark Plug Replace question

This is not helpful because it does not cover my problem - - bolts instead of studs that I can not get out.

Re: Spark Plug Replace question

uh what? studs? they all use bolts as far as I know. What else would they use?

you're most likely just not pulling hard enough. They do require some force to overcome the suction.
