If you get a socket and ratchet or breaker bar on it, you should be about to push it down then remove the belt. I would suggest pushing down and removing the belt off of the alternator. You will understand when you try this.   john heath (Jheath6) New Member Username: Jheath6 Post Number: 20 Registered: 09-2003 Posted on Sunday, September 21, 2003 - 05:16 am:    is it spring loaded then because i see a matal tab coming out of the tensioner body.   Joey (Joey4420) Member Username: Joey4420 Post Number: 222 Registered: 04-2003 Posted on Sunday, September 21, 2003 - 07:50 am:    the metal tab coming out of the tensioner body is to hold the unit in place on the engine. The arm part of the tensioner is spring loaded. It will move in a downward motion when you attach the socket to the bolt at the pulley. Try to get the best leverage that you can on the pulley protion, with out breaking the fan that is. Than you will be pushing down and to the right. Hope this helps.   Erik Olson (Jon) Senior Member Username: Jon Post Number: 476 Registered: 02-2002 Posted on Sunday, September 21, 2003 - 08:23 am:    FWIW the tensioner arm is 15mm on my 95. Rotates clockwise about ten degrees to allow fitting of belt. e   Greg French (Gregfrench) Senior Member Username: Gregfrench Post Number: 606 Registered: 11-2002 Posted on Sunday, September 21, 2003 - 11:44 am:    It is spring loaded and self-tighnening.   john heath (Jheath6) New Member Username: Jheath6 Post Number: 21 Registered: 09-2003 Posted on Sunday, September 21, 2003 - 09:09 pm:    yep all done and thanks to everyone here my tach is working perfect again and to greg yes it is spring loaded and self tightening not so hard to do when you get good advice. thanks guys
