Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
This is a fairly simple procedure.
On the top of your engine, you see the cover that says Ecotec, you need to disconnect the wiring and remove this cover to access the spark plugs are underneath it..
The cover is the coil tower assembly. Quite often, the spark plug wires will stay on the plugs. Just pull the plug wires off of the plugs and snap them back onto the coil housing....
Please let me know if you have any further questions...
