Where is spark plug # 8 located? - 2002 Cadillac Seville

Cars have 4-8 spark plugs located on the engine block each is connected to the distributor cap with a cord.

The spark plugs are located under the four spark plug wires that go through the middle of the valve cover on top of the engine. With a twisting motion, remove the plug wires from the spark plugs. Then using a 5/8 inch spark plug socket and inch extension on a 3/8 inch ratchet, remove the spark plugs. Gap the new plugs to the correct gap (located on the label on the underside of the hood), and in stall into the holes in the valve cover using only your hand to get them started, then tightening with the ratchet. Then reinstall the wires back to their original locations, and you are finished.....

Hope this helps (remember to rate this answer),

1-8-4-3-6-5-7-2 The #1 spark plug is the front spark plug on the drivers side and the cylinder location in order from front to back on the drivers side is 1-3-5-7 and on the passenger side it is 2-4-6-8. The ignition rotor rotation is clockwise.

If your Distributor cap is not numbered then replace the new wires, or transfer the old ones to the new distributor cap one wire at a time. Identify the #1 spark plug wire and start from there.

4cyl. located on top follow spark plug wires to the spark plugs. 6 and 8 cyl. located on the sides just above the intake and exuast ports.

The #8 coil and spark plug are located on the drivers side rear of the engine. You will need a 7mm socket to remove the bolt that holds the coil down. After the bolt is out, pull the coil upwards and remove. Next you will need a 9/16" spark plug socket to remove the spark plug which is located in the hole that the coil came out of. The spark plugs in a 5.4L engine are sometimes frozen into the engine. If it is very hard to turn the plug, try spraying some WD-40 down the hole onto the plug and let it soak in for a while. Do not try to force the plug to turn, it will break and a special plug extractor will be needed to remove it.
Hope this helps you!
