Chrysler manufactured millions of cars with the battery inside the front fender, they are not damaged by engine heat in that location.
The first step in replacing the battery is to disconnect the negative cable from the left spring tower, not shown in the video.
Removing the wheel can make the job easier if you have a jack, jack stand and impact gun handy but it is not necessary, the battery can be accessed by turning the front wheels to the right.
Chrysler paid 12 minutes labor to replace batteries located in the engine compartment, 18 minutes for batteries inside the fender.
