To find it, you need to:
1. Determine your Eclipse's year and engine: This information is usually found on your vehicle's registration or the driver's side dashboard. Knowing the engine (e.g., 2.0L, 2.4L, V6) is crucial.
2. Consult a repair manual or online resources: Once you have the year and engine, search online for "[Your Eclipse Year] [Your Engine] coil pack location". Sites like YouTube often have videos showing the location. A repair manual specific to your vehicle will give you the most accurate information.
3. Look near the top of the engine: Coil packs are usually located on top of the engine, near the spark plugs. They are often black rectangular or cylindrical components.
Without knowing the specific year and engine of your Mitsubishi Eclipse, I cannot provide a precise location. Always use caution when working near the engine and electrical components.
