In this year of Malibu there were 2 engines avail depending on the trim level of the car, one is a 2.2 liter 4 cylinder (base engine) and a 3.5 liter V6 (LS trim), on both engine the spark plugs are located in the cylinder head(s), the reason you can't see them is that each spark plug has an individual ignition coil, it is what is called a direct fire ignition system, there are no spark plug wires, to access the spark plug you must remove each coil from over the spark plug, the plug sits down in a deep well and u will need a thin walled spark plug socket and short extansion(s) to remove it.

    here are more detailed instructions for the 4 cylinder 2.2 liter.

    In the Malibu 4 cyl the spark system in integrated into the engine cover. What I did... With the hood up and facing the engine. There is a wiring harness connector which plugs in to the right hand side. 1- Pull out the orange colored positive connector latch. 2- Pull of the black connector (make sure you push the plastic lock)
    This is the tricky part.. The cover must be removed straight up! ANy side force will break the watertight boots which connect the plugs themselves to the spark/emgine cover.
    A- There are 4 bolts in the top of the cover holding it on. REmove these bolts (they are about 3 inches long) B- Move the fuel lines and anything else that might prevent you from lifting the cover straight up. I can't stress this enough. I broke mine the first time.
    It comes of hard bu keep at it with slow steady force. You can wiggle it a little but not much. It will eventually come off.
    Once you remove the spark dist cover assembly you will see the plugs and have a good understanding of what I'm talking about.
    Make sure you blow out the holes and surrounding area before you remove the plugs to keep dirt out.
    I usually loosen all the plugs and then use a short (6 inch) piece of 3/16 rubber hose to lift out the plugs. Push the end of the hose over the end of the spark plug. The plug goes fits snugly into the hose and lift it out. Work good for re-installation as well.

Thanks, Glad I can try, however, its very easy to locate. if there's a plastic trim/cover over the engine remove-it and set aside. The Spark Plugs is sitting right below the Ignition Cassette or Coil as it is also referred to, it may say ECOTEC on the cover, secondly, remove the electrical harness on right side of the cassette, it's just above the oil filler cap, then remove the four, 10 bolts and pull-up the Ignition cassette. All four Spark Plugs will be there for easy removal and replacement. Reverse actions will be in order... Here is what you will need to perform the repair: 3/8 in ratchet, 5/8 in Spark-plug Socket, 3/8 in extension 12 ins long and a #10 socket. For your 2004 Chevrolet Malibu with a 2.2 liter ECOTEC Engine. Hope this DIY was helpful!

2004 Chevrolet Malibu mix v6 LS engine turns but will not start

Check for fuel, spark, and then compression. Fuel problems can be pump, pump relay, fuse, filter, line, etc. Spark problems can be distributor module, distributor, coil packs, power to distributor or coil packs, plug wires. Compression problems would be piston rings, piston walls, piston rods.

The spark plug gap for this application is 0.60 Although, the spark plugs are Iridium plugs and are pre set by the manufacuter and should not be tampered with due to damaging the diode on the plug. The correct application for this vehicle should be AC DELC0 IRRIDIUM SPARK PLUGS.

2004 chevy malibu 4 cylinder seems like it is fighting for gas and it bogs down. there is crackling under the hood like rice crispies in milk.what could it be?

Try opening the hood at night and while the engine is running, carefully look for blue sparks around the plug wires. A lot of time when the wires get old, the electricity will arc to any metal parts that it can. Check along the whole length of the wires and down by the spark plugs. Also make sure all of the spark plug boots are properly connected to the spark plugs by pushing them on firmly when the engine is off.

Replacing spark plugs on a 2004 chevy malibu

2.2L Engine
  1. Observe the following service precautions:

    Allow the engine to cool before removing the spark plugs. Attempting to remove spark plugs from a hot engine can cause the spark plugs to seize. This can damage the cylinder head threads. Clean the spark plug recess area before removing the spark plug. Failure to do so can result in engine damage due to dirt or foreign material entering the cylinder head, or in contamination of the cylinder head threads. Contaminated threads may prevent proper seating of the new spark plug. Use only the spark plugs specified for use in the vehicle. Do not install spark plugs that are either hotter or colder than those specified for the vehicle. Installing spark plugs of another type can severely damage the engine.
  2. Turn the ignition OFF .
  3. Disconnect the Electronic Ignition (EI) module harness connector.
  4. Remove the spark plugs using a 5 / 8 inch spark plug socket.

To install:

WARNING Do not coat spark plug threads with anti-seize compound. If anti-seize compound is used and spark plugs are over-torqued, damage to the cylinder head threads may result.
  1. Inspect the gap on the new spark plugs, re-gap the plugs as required. The spark plug gap specification is 42 inch. (1.0 mm).
  2. Install the spark plugs and tighten to 15 ft. lbs. (20 Nm).
  3. Apply dielectric compound to the spark plug boots and make sure no corrosion is present.
  4. Install the ignition coil housing to cam cover and attachment bolts.
  5. Tighten the ignition coil housing bolts to 89 inch. lbs. (10 Nm).
  6. Connect the EI module harness connector. Push in until a click is heard and pull back to confirm a positive engagement.

2004 chevy malibu classic spark plug replacement

Search for the engine model ECOTec 2.2 rather then Malibu. It is very easy to replace the plugs, they are DEEP inside the engine so you will need a 6" socket extension for the spark plug socket. Needle nose pliers were required to retrieve the socket on the first plug. Don't push down hard on the plug, just enough to engage the nut. Full screen photo sequence is available at:
