Here's a breakdown of what makes it moderately difficult:
* Access: You'll likely need to maneuver around other components in the engine bay to reach the starter and the cable connection. It can be cramped.
* Bolts: The cable is secured with bolts that can be stubborn, especially if they've been exposed to the elements. You'll need a wrench or socket of the appropriate size. Rust and corrosion are common, potentially requiring penetrating oil and some effort.
* Cable Size and Weight: The positive cable is thick and heavy. Managing it while disconnecting and reconnecting can be a bit awkward.
* Electrical Safety: Always disconnect the negative battery terminal *first* before working on any positive connections to prevent accidental short circuits.
What you'll need:
* New positive battery cable: Get the correct one for your year and model Expedition.
* Wrench or socket set: Appropriate sizes for the bolts securing the cable to the battery and starter.
* Penetrating oil (like PB Blaster): Highly recommended to loosen rusted bolts.
* Socket wrench extension(s): May be necessary to reach the bolts.
* Gloves: Protect your hands.
* Safety glasses: Protect your eyes.
* A jack and jack stands (optional but recommended): Improves access, especially if you have large hands. Raising the front of the vehicle may give you more room to work.
If you're not comfortable with basic car repair, it's best to take it to a mechanic. Incorrectly installing the cable could damage your starter, battery, or even cause a fire.
