How to Install an Ignition Coil in a 2005 Dodge Stratus

In the mid-1990s, Dodges complete lineup of cars underwent a total modernization. One of these modernizing steps was to replace the aging Dodge Spirit with the new Stratus. The 2005 Dodge Stratus comes in two trim levels: SXT and R/T, both of which come as a coupe or sedan. A 147-horsepower, 2.4-liter, four-cylinder engine is standard in the base level SXT. This engine has an interesting ignition system that has two coil-on-plug coil packs, one on the No. 2 cylinder and one on the No. 4 cylinder; the other two cylinders plug into these coil packs. Despite its unusual nature, installing a coil in the 2005 Stratus with a 2.4-liter engine is a straightforward task.
