hi there,to replace the rear spark plugs you virtually reach over the motor and do everything by feel .it is quite an awkward reach to get at them,but the hardest one is the one closest to the drivers side. there isn't much room.if it helps you can also hang a small mirror there and this helps a bit to see what you are doing.hope this helps.

Remove the spark plug wires from your 2000 Chevy Impala spark plugs. Remove the spark plugs with a 5/8 deep well socket by turning the socket to the left. Reverse the process to install the new spark plugs.
Every gas burning internal combustion engine has spark plugs. Diesel engines do not. Your Impala is not a diesel, so it has plugs.
Need to replace rear spark plugs
Disconnect the battery, remove the spark plug covers and cable, and remove the old spark plugs. Put in the new spark plugs, replace the covers and cable, and reconnect the battery.
If you have not replaced the fuel filter in the last 50,000 miles replace it. Also replace the spark plugs and plug wires if you have not done so. Of course replace the air filter every 30,000 miles.
EVERY 60K
you rotate the engine to get to the rear plugs but the front ones are easy to replace
Yes
You have to remove the upper intake manifold.
This info is listed in your owner's manual. Don't have on the replace them at 75,000.
Disconnect the battery, remove the boot cover and spark plug cables, and pull out the old spark plugs. Put in the new spark plugs, replace the boot cover, and spark plug cables, and reconnect the battery.
Easy fix, remove the spark plugs dry everything off. Then go to autozone and get a new valve cover gasket and replace it. This will solve the problem. By the way replace the 4 spark plugs at this time save you having to do it at some other time.
