My brothers eclipse (2.4 v6 I think) uses a special tool for the timing belt tensioner. It was just a plate with 2 pins and a square drive hole. Instead of ordering it and waiting we ran to the local metal warehouse, found some rod the correct size and I welded the pins on some plate stock and welded a bolt on as well. We just used a torque wrench (per the procedure) on the bolt and voila! Job done.
