Aux belt

Because it does not look good anymore. Looks like it could snap any minute. It has long cracks in the middle of the belt..

Just thought there was something esle to thange with it, a tensioner of some kind?

the aux-belt is the one, in front of the cam belt, rigth?

"bottom crank pully" is that the one pulling the fan, or am i way off?

Just used this guide to do mine, thanks. It took me about 15 min.

 

What I did;

 

Removed battery for more room

Loosened top clamp on intercooler pipe and removed

Loosened other clamp at bottom of that section and swiveled it round to face left

14mm socket set round the tensioner nut with short breaker bar over the shaft for more leverage

Have wrench around 2pm position or as horizontal as possible.

Push down as if to tighten and the tensioner will move letting you pull the slack belt off at the top right pas pully

Remove belt carefully involving going round the fan.

Put the new belt in place doing the reverse of taking it off using the diagram that should be in the engine bay (if not take a pic of it 1st?)

Push down as if to tighten the nut on the tensioner to move it to slacken the belt enough

Pull the belt over the last pas pully at the top right (set the belt up like this in prep for this moment)

Re aline intercooler hose and tighten top and bottom

Replace and secure battery

Start and hear it purr again instead of squeaking

Job done.

 

Info is pretty much in this thread but I just went into a bit more detail incase it helps anyone in future.
