How to get to the plugs on a 1995 Cadilac Deville 4.9
SOURCE: replacing spark plugs
Changing spark plugs in your Cad is not an easy thing. I tried it using the chiltons manual and it took five hours. Just in case you want to try it yourself you will need to start by removing the engine cover (two screws easy to locate). Next step is the tricky and tedious part. A black cylider with small vacuum tubes located at the rear center next to firewall needs to be removed. It is attached to the engine by an somewhat difficult to reach bolt and a almost impossible lower bolt that can be acessed underneath if you can find it and have hand of a ten year old. I removed it from bottom of vehicle than tightened it after from the top this is by far the most difficult of the process watch your knuckles. This vacuum valve is connected to a silver hose which needs to be unscrewed to remove valve two screws attach it from the bottom. This is another difficult one. Make sure the your socket is firmly onto the wrench, one socket remains hidden after it fell off, making a extra trip to the store neccasary after losing it. Move valve out of the way as best you can and what remaing are 8 bolts holding on the "ignition coil assembly". These shoul be taken out in a "W" pattern: top bottom top bottom. Remove these and remove panel another very tight fit. Remove spark plug boots and take out spark plugs and keep in order so that spark plug damage can be assessed according to corrisponding cyclider. Repeat for front plugs and reverse steps to reassemble. Spark plugs come pregaped. Start with the rear plugs, they are the most difficult, and you have a better idea how much time it will take.

The sparks plugs are located on the side of the engine,there will be spark plug wires covering them the number of spark plugs in your car depend on the size of the engine, like if you have a v8 there will be 8 of them if you have a v6 there will be six of them and so on. There are no spark plug wires on the 2000-up Northstar engines. They use coil on plug design. If you remove the screws that holds the coil pack to the top of the cam covers, you will see the tops of the spark plugs directly underneath. They are in the center of the cam covers.
