To change the freeze plugs on a 2000 Subaru Outback, first drain the coolant and remove any components obstructing access to the freeze plugs. Use a punch or a screwdriver to carefully tap out the old freeze plugs. Clean the surfaces where the new plugs will be installed, then apply a sealant if desired, and press the new freeze plugs into place, ensuring they are seated properly. Finally, reassemble any removed components and refill the cooling system with coolant.
