You likely have two mechanical tensioners. If so you'll need a plain jane 15 or 16mm socket (forgot which) or a 5/8" works fine as well. Thats to release the belts. You may need a torx bit to remove the actual pulley from the tensioner. Either case, make sure you have a full socket set, torx set, and allen head set. you'll need all of them anyway to work on these cars. GL!!
