Where are the spark plugs located on 2.2 liter engine a Saturn L200 series?

The spark plugs on a Saturn L200 (2.2L engine) are located on top of the engine, under the plastic engine cover. To access them, you'll need to remove the engine cover. They're arranged in a somewhat "V" configuration, but the exact placement relative to each other depends on whether you have the 4-cylinder or the V6. The L200 only came with a 4-cylinder 2.2L, so it's a 4 cylinder inline configuration. You'll likely find them fairly evenly spaced along the valve cover. A repair manual specific to your year and model Saturn L200 would provide the most accurate and detailed location information.
