Cut them off- after 10 years it's time to replace
remove the ignition coils on the intake and they are underneath it. your vehicle has distributorless ignition, therfore there aren't any spark plug wires, instead it has individual ignition coils with the spark plugs directly underneath them.
if you have ignition coils you have to remove them and the intake tube (3000) then you can take the spark plugs out
Spark plugs are hidden under the plastic engine cover. You have to remove the ignition module as well which fits over the four spark plugs.
I don't think your car has a distributor cap. I believe it has an electronic ignition and only has an ignition coil to deliver spark to the plugs. Where this is located, I do not know.
They are under the 6 ignition coils. There is a coil for each spark plug. You have to remove the coils, and then remove the plugs.
Take off the plastic engine cover with the three or four bolts pending on which model, then remove the ignition coils and ignition coil plugs, and presto! you have access to all your spark plugs.
2003 c320. So a v-6 correct? They are located on both sides of the engine. Your engine will have spark plug cable wires going from the ignition coils to the spark plugs, you need to remove the cables off the plugs before you can remove the spark plugs.
Remove the engine covers and carefully remove the ignition wires from the spark plugs, there are 12 of them, then remove the spark plugs with a 5/8 plug socket. Make sure the gap is correct on new plugs put a bit of anti seize on the threads then install the new plugs...
The spark plugs are beneath the cover marked Quad 4. This cover holds the ignition coils that spark the plugs. Remove the cover and you will be able to see the spark plug holes on the top.
They are located below the black plastic where you see the "ECOtec" logo on the engine top. You have to remove screws and pull out the ignition coils to see the spark plugs. By the way GM's 2.2 Ecotec use direct ignition, so there's no spark plugs wires.
No, spark plugs do not cause ignition in diesels. The fuel compression causes ignition
with a 10mm socket remove the two ignition coils and the two spark plug wires, using a 5/8 spark plug socket and one long extension and a ratchet remove the spark plugs and install the new ones
