It should be the same as for a 2002 Mercury Cougar which is answered in WikiAnswer under the Question; " How to remove alternator from a 2002 Mercury Cougar 2.5L V6." The 2000 Cougar may be different by having an upper alternator BOLT. If it does, and you can't lift the bolt out (after fully loosening the bolt), lower the alternator and you can, then, lift the bolt out. When you begin to install the alternator (attach the power wire, and the wire connector) place the BOLT in the upper hole in the alternator, and THEN, raise the alternator to install.
