šŸ”§ Savana - Battery Replacement

Replacing the battery restores reliable starting and prevents low-voltage issues (slow crank, warning lights, no-start). On your Savana, the battery sits under the hood and is held down with a clamp and bolt.

Difficulty Level: Beginner | Estimated Time: 0.5-1.0 hours

Assumption: battery is under-hood, top-post terminals, standard hold-down.


āš ļø Safety & Precautions

  • āš ļø Turn ignition OFF, remove the key, and keep doors closed while you work.
  • āš ļø Never let a tool touch both battery posts (or post-to-metal) at the same time.
  • āš ļø Disconnect the negative (-) cable first and reconnect it last to reduce short-circuit risk.
  • āš ļø Wear eye protection—battery corrosion is acidic.
  • āš ļø Do not smoke or create sparks near the battery.
  • šŸ”§ Battery disconnect is recommended; expect radio presets/clock to reset.

šŸ”§ Required Tools

You'll need the following tools for this repair:

  • 10mm socket
  • 13mm socket
  • 3/8" ratchet
  • 6" socket extension
  • Torque wrench (3/8" drive)
  • Battery terminal puller (specialty)
  • Battery post/terminal cleaning brush
  • Trim clip tool
  • Shop rags
  • Nitrile gloves
  • Safety glasses

šŸ”© Required Parts

HowToo sells all the parts you need for this repair:

  • 12V starting battery (correct group size for your Savana) - Qty: 1
  • Battery terminal anti-corrosion spray - Qty: 1
  • Battery terminal felt washers - Qty: 1 set

šŸ“‹ Before You Begin

  • Park on level ground, shift to P, and set the parking brake.
  • Open the hood and let the engine bay cool if it’s hot.
  • Lay out tools so nothing metal can fall across the battery.
  • If you see heavy crusty buildup (white/blue powder), plan to clean the terminals before installing the new battery.

šŸ”Ø Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the battery

  • Open the hood and locate the battery.
  • If a cover or air duct blocks access, release clips using a trim clip tool and set it aside with shop rags under it.

Step 2: Disconnect the negative (-) battery cable

  • Use a 10mm socket with a 3/8" ratchet to loosen the negative terminal clamp nut.
  • Twist and lift the cable end off the negative post, then tuck it aside so it cannot spring back.
  • If it’s stuck, use a battery terminal puller (specialty) (this tool gently pushes the clamp off without hammering).

Step 3: Disconnect the positive (+) battery cable

  • Use a 10mm socket with a 3/8" ratchet to loosen the positive terminal clamp nut.
  • Lift the cable end off and position it away from the battery.
  • Tip: Cover the + cable with a rag.

Step 4: Remove the battery hold-down

  • Locate the hold-down clamp at the base of the battery.
  • Use a 13mm socket, 6" socket extension, and 3/8" ratchet to remove the hold-down bolt.
  • Remove the clamp and set it aside.

Step 5: Remove the old battery

  • Wearing nitrile gloves and safety glasses, lift the battery straight up and out.
  • Set it on the ground upright (batteries are heavy and can leak if tipped).

Step 6: Clean the tray and terminals

  • Wipe the battery tray clean using shop rags.
  • Clean the inside of both cable clamps using a battery post/terminal cleaning brush until shiny metal appears.
  • If you’re using felt washers, place them on the battery posts now.

Step 7: Install the new battery

  • Place the new battery into the tray in the same orientation as the old one (posts aligned with cables).
  • Reinstall the hold-down clamp and bolt using a 13mm socket, 6" socket extension, and 3/8" ratchet.
  • Tighten with a torque wrench (3/8" drive): Torque to 20 Nm (15 ft-lbs).

Step 8: Reconnect the positive (+) cable first

  • Install the positive clamp fully down on the positive post.
  • Tighten using a 10mm socket and torque wrench (3/8" drive): Torque to 15 Nm (11 ft-lbs).
  • Spray light protection on the terminal using battery terminal anti-corrosion spray.

Step 9: Reconnect the negative (-) cable last

  • Install the negative clamp fully down on the negative post.
  • Tighten using a 10mm socket and torque wrench (3/8" drive): Torque to 15 Nm (11 ft-lbs).
  • Spray light protection on the terminal using battery terminal anti-corrosion spray.

Step 10: Reinstall any covers and do a quick check

  • Reinstall any battery cover/ducting using the trim clip tool as needed.
  • Gently try to move the battery by hand—there should be no shifting.
  • Verify both clamps are fully seated and not crooked.

āœ… After Repair

  • Start the engine and confirm it cranks strongly.
  • Check that no battery/charging warnings stay on after starting.
  • Set the clock and restore radio presets if needed.
  • If the idle seems a little odd at first, let it idle a few minutes with all accessories off, then drive normally.
  • Return the old battery for a core credit (most parts stores require this).
