I recently purchased a '95 Mystique LS with the 2.5 Duratec, and 57K miles. It runs great, but I plan to replace the waterpump soon. I also hear a faint and discontinuous click..click..clock in the same area during idle. Can't hear it when I rev it up. I used a long screwdriver and was able to locate the sound at the tensioner assembly. I attached a metal extension tube to my Sears 3/8" ratchet, and was able to release the belt tension. I did this with the engine idling (be very carfull near a revolving belt. This is not for a novice), and the noise susided with the stopping of the belt. I did it a few times to be sure. I also listened in different areas, as these clicks will "telegraph" to adjacent areas. Anyway, I am pretty sure it's the tensioner in my case.
I saw a T40 Torx head screw in the center, and with a Torx socket and breaker bar was actually able to break it loose! I retightend it, as I need to learn more about this replacement. Has anyone replaced the tensioner assembly? With the belt off, is the internal spring unsprung and safe? Any help or tips are appreciated.
