This automotive maintenance tutorial was specifically written to assist owners of the tenth generation (2014, 2015, 2016, 2017 and 2018) GM Chevy Impala in changing a dead 12 volt car battery in the engine bay.

Owners of other General Motors vehicles such as the Malibu, Cruze, Camaro, Sonic, Spark, Volt, Corvette, Trax, Equinox, Traverse, Tahoe, Suburban, SS Sedan, Bolt, Colorado, Silverado, Buick Verano, Regal, LaCrosse, Cascada, Encore, Envision, Enclave, Canyon, Sierra 1500, Terrain, Acadia, Yukon, Savana, ATS, CTS, XTS, CT6, XT5, SRX and Escalade may also find these DIY instructions to be helpful.

The OEM battery in this 2014 Impala was an ACDelco 48PS.

A few other compatible "Group Size" 48 or H6 batteries with their part numbers are as follows: Bosch S6585B, EverStart MAXX-H6 and ACDelco 48AGM.

The tools required to complete this procedure include a 10mm socket, a 1/4" drive ratchet, a 13mm socket, a 6" or 9" extension bar and a 3/8" drive ratchet.

Old Battery Exposed
The first two steps are to open the hood and then move to the right (driver) side of the engine bay.

The 12 volt car battery is located to the left of the electrical fuse box and just behind the driver side headlight housing.

There are two retaining clips holding the black plastic battery cover in place.

Push in the release tab on the right rear clip to release it.

Then push in the release tab on the left rear clip.

Pull the plastic cover straight off the top of the battery and set it aside in a safe place.

Loosen the negative "-" terminal nut by turning it counterclockwise with a 10mm socket and a 1/4" drive ratchet.

Pull the negative terminal straight off the "-" battery post.

Wrap the terminal in a small towel and tuck it away on the side of the battery to help prevent accidental contact.

13mm & Extension Bar
Loosen the nut on the positive terminal by turning it counterclockwise with the 10mm socket and a 1/4" drive ratchet.

Pull the power distribution board off the top of the old battery.

(I later discovered that two of the wires attached to the power distribution board need to be removed in order to make enough room to lift out the old battery. See the pictures below.)

Metal Ring & Strap
There is a grey plastic block at the front bottom edge of the battery that acts as a hold down clamp.

Attach your 9" extension bar to a 13mm socket and a 3/8" drive ratchet.

Loosen the 13mm bolt by turning it counterclockwise.

Lift the battery hold down clamp out of the engine bay and set it aside in a safe place.

There is a metal ring and strap attached to the positive "+" battery post.

Remove 2nd 10mm Nut
Pull the metal ring off the positive battery post and tuck it away on the side of the battery.

As I mentioned earlier, I had to back track and remove two wires from the power distribution board in order to lift out the battery.

Remove the wire at the rear of the power distribution board and near the coolant reservoir tank by turning the 10mm nut in the counterclockwise direction.

Then remove the wire near the front left corner of the board by turning the 10mm nut counterclockwise.

Clean Off Battery Tray
Carefully lift the old battery out of the engine bay.

Gently set the old battery on the ground. Avoid dropping or tipping over the battery to prevent from having acid leak out.

Be sure to bring the old battery with your to Walmart or the auto parts store to avoid having to pay a "core" or "disposal" charge. The retailer will also have the old battery properly recycled.

If you can wait a few days, I recommend buying the Bosch S6585B since it has excellent reviews on Amazon.

Clean off any debris from the battery tray so that the new battery will rest evenly on it.

Carefully lower the new battery in to the engine bay with the "+" positive post near the rear (closest to the windshield) and the negative "-" terminal closer to the front of the car (by the headlight).

Lower the grey plastic battery hold down clamp down on to the front edge of the battery tray.

Tighten the 13mm bolt by turning it clockwise.

Check to see if the new battery can be rocked, slid or moved around on the tray. If the new battery can be moved, tighten the 13mm bolt an extra turn or two.

Replace Positive Terminal
Push the two cables back on to the power distribution board and tighten the 10mm nuts in the clockwise direction.

If you've had a problem with corrosion (white or blue powder) building up on the battery terminals, consider installing some felt anti-corrosion washers on to the battery posts.

Push the positive terminal on to the "+" battery post and tighten the 10mm nut in the clockwise direction.

Try to avoid over tightening the terminal nut to prevent from cracking or damaging the battery post which could lead to an acid leak.
