Changing spark plugs on 2004 Grand Prix

How do you remove the old spark plugs?
We've tried pulling them straight out using the rubber part, twisting and turning the metal tubing the rubber is attached to...
and they aren't budging?
Our owner's manual doesn't say a thing about it either....

How to remove a stuck cd in cd player of 2004 pontiac grand prix

I've used my technician tweezers to get them out before, I'm unfamiliar with that particular model, but if you can see the disk is straight inside the opening level with the insert slot it should be do able. Just don't force anything to much, if the spindle is up in the player it might not be possible as the hole in the center of the cd would have the spindle to spin the disk inside it. As long as it's a clean shot to the disk it should be fine to turn key on and try the eject while pulling with tweezers. A couple of butter knives might even work if you can use them somewhat like chop sticks. Hope this helps.

How do i change the back spark plugs on a 1999 grand prix 3.8 v6

Just a tight situation. Small arms help. Best access is from drivers side reaching down between firewall and engine. You will have to find and follow a plug wire one at a time, twist and pull off. ( careful wires if old will break off and a new set will be needed). Using same technique install the spark plug socket on the plug and appropriate extensions to get a good working clearance to loosen plug. Reinstall new plug in reverse order after checking gap. Plugs are in at an angles. You can see them if you really lean in and look down behind engine. It will just be a trial and error on gaining access and changing the plugs one at a time. A plug socket, a 2 inch extension and a 3/8 drive ratchet should do. Don't scrimp on cheap plugs. Good luck

My friend has asked me to change her sparkplugs on a 2004 grand prix. I was wondering if it's neccessary to change the wires and caps as well?? Also, I read some where that the spark plugs should be at...

Torquing isn't really necessary if you have been changing plugs for a long time (you develop a "feel" for it) Don't "animal" them down but don't leave any loose either. ALWAYS use anti-seize compound on the threads though. When removing the old ones be really careful with any that are stuck...the heads are aluminum and you can easily pull the threads out. As for wires etc, if you have them (many don't) it's likely they are still good but always do a visual inspection and wipe them off with silicone on a rag.

Hi. here's the procedure on how to replace your spark plugs. Spark plug location is in this procedure.

  • Park the car in cool, shady area and allow the engine to cool.
  • Step 2 Remove the parts of the Grand Am engine that hinder access to the spark plugs. For a 2.2 L engine, remove the ignition coil housing. For a 2.4 L engine, remove the bolts that hold the retaining ignition coil and disconnect the electrical connector. Pull the assembly straight up and away from the engine to remove it. For a 3.1 L engine, remove the air cleaner. For a 3.4 L engine, remove the windshield wiper module cover and rotate the engine for service access to the rear spark plugs.
  • Step 3 Locate the spark plug wire and grab it by the spark plug boot. Twist the boot in both directions and pull back to remove the wire.
  • Step 4 Insert the spark plug socket over the old spark pull and unscrew it from the cylinder well. Remove the old spark plug.
  • Step 5 Lubricate the threads of the new spark plug and screw it into the cylinder well.
  • Step 6 Test the tension and adjust it to the required setting. It needs to be 15 ft-lbs. for a 2.2 L engine, 16 ft-lbs. for a 2.4 L engine, 13 ft-lbs. for a 3.1 L engine, and 11 ft-lbs. for a 3.L engine.
  • Step 7 Reconnect the spark plug wire and twist it to lock the plug in place.
  • Step 8 Repeat Steps 3 through 7 for the remaining spark plugs.
  • Step 9 Replace all of the parts that were removed from the Grand Am in Step 2 to reach to the spark plugs.

    Spark Plug Wire Removal

    normal spark plug wires just pull off. thet might have a clip and groove type connection. if you've tried to pull it off, and it seems like it's stuck. it is. try twisting the boot to break the surface tension between the rubber boot and the spark plug porcelain. pull straight out. use a pair of pliers. if the connector come off the wire, and the plugs are recessed, use needle nose to pull the connector off. you can also pierce the boot with an awl to vent air into the boot to relieve vacuum.

    Removing Plug Wires from '02 Pontiac Grand Prix, 3.8 Liter V6

    often times the connection inside the plug boot gets corroded and it's almost impossible to remove the wires with out damage. when this happens I gennerally replace the wires anyway this saves you problems in the long run . the sparkplug wire removalk pliers are a good investment however they are only as good if the boots themselves are not siezed up on the plugs. I have had this happen alot over the 20 years i been working on vehicles. I usually just twist and pull on the boots till they come off and not worry about damaging them because they should get replaced anyway the new plug wires have a antiseize lubricant to keep from this happening in the future
