The above was a quick answer for a part you requested, but it is not a one stop fix for your problem. You have a really nice car with exceptionally low miles that probably has all the original hoses, pumps, filters, oil, coolant, battery etc.
It will take some time, but you need to refresh everything. If that battery is more than two years old, get another. Crossfire are very temperamental as to battery. Odyssey batteries have a good reputation. Get a new Mann HU718/5x and a decent 0w-40 or 5w-40 full synthetic oil, you should use Zerex G05 anti freeze, Pentosin CHF 11s power steering fluid and change the brake fluid. The owner manual is your friend for all the proper fluids. DO not substitute unless you do diligent research!
You are in the right place for help.
