Re: Fitting Auxilary Belt tensioner
The tensioner automatically tensions to the correct level.
Its quite tricky to get the belt on but the tensioner is easy to fit..
Remove the old belt and tensioner, and screw the new one on so that the tensioner wheel is pointing upwards. Do up the bolt tight.
Then thread the belt around all the other pulleys. You then need a 15mm spanner to fit on the bolt on the wheel part. Use the spanner to lever the tensioner anticlockwise out of the way whilst you thread the belt over it. When it is over it release the tension and the job is done.
You may need to thread the spanner through the belt before levering the tensioner, otherwise the belt will be on the wrong side of the spanner.
The bolt on the tensioner that you use to lever is a left hand thread so it won't come undone.
I hope that all makes sense. Its far harder to do if your car has aircon.
