QuestionWhat is the procedure for battery replacement in a 2000 Chrysler 300M? Do I need to remove the tire or are there short cuts?
AnswerHi Kevin,
Here it is from the '98 manual for the Concorde which probably applies to your car:
Turn steering wheel all the way to the right
Verify ignition switch and all accessories are off.
Disconnect and isolate electrically (wrap in plastic) the negative battery cable "remote" terminal from the remote battery post on the strut tower.
Remove air cleaner housing
Remove battery splash shield
Remove two short battery hold down bolts
Slide battery rearward to disconnect the negative and positive battey terminals from the battery
Slide bettery toward rear of vehicle and lift out through wheel well opening
Installation is the reverse.
I just bought on eBay the manual for the 300m but it will be a week or so till I receive it. I hope the above is helpful to you.
