First of all, battery maintenance is important. Also, you need to wear eye protection and gloves. If there is corrosion, remove the battery, clean it with baking soda, and make sure the battery tray and clamps are secure. Use a slow-rate charger for discharged batteries.

Loosen the left-front wheel lug nuts, then raise the front of the vehicle and support it on jackstands. Remove the left-front wheel and inner fender splash shield. Also remove the engine under cover. Remove the fuse box assembly mounting bolts and position it to the side. Remove the Powertrain Control Module (PCM) mounting bolts, then position it to the side. If necessary, also remove the PCM mount for better access. Detach any wiring harness clips from the battery tray, then remove the battery tray mounting bolts - accessed by working from the engine compartment, fenderwell, and from below the vehicle. Remove the battery tray, rotating it as necessary. Installation is the reverse of removal.

To disconnect the battery, loosen the cable end nut of the remote negative terminal, disconnect the cable from the remote ground terminal, attach the plastic insulator portion of the cable to the stud, and reinstall the nut.

Transfer the thermal guard to the new battery.

If a maintenance-required battery is installed, check the electrolyte level in each cell and add distilled water if necessary.
