You want to do it? I'm guessing spark plugs? Pull spark plug boots off, its going to be tougher then you think, they are on there pretty good, then with a long 3/8 extension, and a ratchet, and a 5/8s spark plug socket remove the spark plug. Reverse order to put in. Make sure you put anti seeze on the threads when you put them back in, and do not mix up the spark plug wires.

I want to do any oil and filter change on my 2006 Astra 4 door hatch it is Holden GM model AH CDx it has an ecotec 1.8l unleaded petrol engine

So what is the problem? The new filter for a Z18XE screws directly on to the front of the engine block behind the radiator, and the oil drains out of the drain plug at the base of the sump. The Z18XER only differs in that the filter sits in a round black housing visible from the top right of the engine and is requires a 32mm spanner to remove the cover. The filter is different from that on the Z18XE

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!

How do I remove the ECOTec 2.2 panel to get to the plugs

the cutie pie plastic panel on top of motor, ah unscrew it?
the FSM cover this step by step. (i think there is no cutie cover)
some just say remove the cover , knowing the shop mech, can see the screws. if it snaps off, they might say that in the book.
think about that, if there are no screws, how would it attach./?
yes, snaps.
ah the spark rail.
ign coil housing replacement.?

Disconnect the EI module harness connector.
Remove the ignition coil housing attachment bolts and remove the ignition coil housing.
with boots.
see the 4 bolts on to in plain sight? those.
then gently pry it up. so as not to break all this weak plastic bs.
put back with dielectric great as the FSM states.
or next time, comes off will fail.

Can you tell me where the spark plugs are located?

Remove the portion that says ECOTEC on the engine. It is just a plastic cover and your plugs will be under there beneath the coil packs. Should be easy to access.

Need to know how to change spark plugs no wires so where r they???

I'm assuming you have the 2.2 Ecotec engine, for they have teh spark plugs hidden under the plastic cap on the engine's valve cover. The plastic cap which should say "2.2 Ecotec" can be removed with 10mm socket, and the valve cover (In case you didn't already know) if the aluminum top piece of the engine. They are a little ways down, so be careful not to cross thread the plug.
Good Luck Blaccent

Where is the oil filter for a 2005 chevy cavalier located

ECOTec 2.4 Liter engine (and all ECOTec engine blocks in 4 cylinder sizes) have a cartridge type oil filter housing on the front of the block, driver's side of the vehicle.

The cap must be removed with a wrench, and the filter pulled out, then the new one put in. Now is usually a good time to replace the O-ring on the cap.

Spark plugs

The spark plugs on the cavalier are under the 2.2 ecotec panel located on the top of the engine. There are no spark plug wires to deal with. The electronic coil pack directly attaches to the plugs with rubber seats like in a spark plug end. Then you use a deep socket ratchet to get the plugs out. Use anti-seize compound when replacing the plugs.

I have a 2004 Chevy Malibu. Bogs down and stalls with acceleration. Check engine light flashes. Idols fine. Changed the MAP as it had a P0101 code along with the P0300. Changed the plugs 3 weeks ago and...

make sure you have ngk or ac delco iridium plugs installed. Also common problem on the 2.2L ecotec is the cat plugging. Easy check is to remove the front o2 sensor (very easy 22mm wrench) and start the car and rev it. If it revs freely now and does not bog the cat is plugged. They are covered fed. emissions warranty 8yr 80k, all gm dealers stock the cats for the 2.2 ecotec.
