In my experiences with tensioners, I've never 'reloaded' one or heard of it being done (doesn't mean it couldn't happen). For $15-$20 each time, I've replaced many by myself, with a new part from NAPA, Advance, Auto Zone, etc.

Replacing the AC belt is probably one of the easiest things to do... Just simply losen the tensioner pulley and remove belt... Install new belt on all the pulleys then tighten the tensioner pulley. Its that easy.

The bolt holding the pulley to the tensioner arm is left hand thread. The nut holding the tensioner to the engine is right hand thread.

First, you make sure you have a diagram of the path of the belt! You can get it from a book, the inside of the hood or make one yourself. Then remove the belt. The nut you used to relieve the tension to remove the belt should remove the tensioner, itself. NOTICE! Some auto parts stores have TWO very similar tensioner pulleys! On my first try the cupped washer on the tensioner bolt rubbed against the radial support ribs on the pulley itself destroying not only the pulley but the belt, also! Be SURE that the new pulley turns freely when the bolt is fully tightened!

THERE IS A BELT TENSIONER BELOW AND JUST TO THE RIGHT OF THE FAN PULLEY. LOOSEN IT COMPLETELY, AND THE NEW BELT SHOULD FIT RIGHT ON. THEN TIGHTEN THE TENSIONER TO TIGHTEN THE BELT, AND YOUR DONE. GOOD LUCK, DANNY.

My daughter has an X2 1993 and it has a cam belt. All models from 1990 will have a cam belt but I'm not sure about the earlier X1 series prior to 1990. If you are replacing the belt, make sure you buy a cam belt kit with the new tensioner pulley assembly. I found this out the hard way when I pulled my daughters car apart to replace the belt. The pulley bearing was stuffed and also the tensioner spring gets weak over time.
