A/C bypass

Welcome to 2CarPros. The belt needed will depend on which Sebring you have. Chrysler used 2 different vehicles under that name. The 4 door and convertible are one car the 2 door coupe is actually an Eclipse with different bodywork. The first 2 images are the sedan and convertible belt routing. The third is the 2 door coupe. They also used different 2.4L engines.
On the 4 door and convertible you should be able to use a shorter belt but I don't find one listed for a non A/C application. That one would be a trial and error but you can get close if you took a piece of string and ran it around the alternator and the crank pulley, pull it tight and get a belt that long, then see if it clears and the tensioner still works without binding.
On the coupes you need to change the belt and the tensioner pulley to use the non-ac belt.
For those the tensioner needs to have a ribbed pulley and the non-ac belt which a parts store should have in stock.

Thank you for that information.
