[s-cars] timing belt replacement special tools

[David Kase]

I concur.  To go in and do a quick timing belt change is not good.  Even
if it was not a component that caused the failure (although I am not
sure what else could have), it's best to replace the water pump and any
idler rollers (I can't remember if the AAN has an idler).  Oil seals are
also easy when things are opened up for the tb change.

The only special tool you really need is the crank positioning tool.
The factory tool sucks but may be your best bet - rent it from Chris @
F5.  Chris can also get the proper parts for you (i.e. correct brand of
water pump,...).

Don't forget the t-stat while you're in there as well as fresh coolant.

If you want to make sure you finish the job the serpentine belt failed  
to complete there are several shortcuts you can take.  The fact that  
you are asking seems to indicate
this will be your first belt change?  You want to look things over and  
find why the serpentine belt made such a mess.  Something may have  
failed to cause it to shred.  You
will need to order parts so why not get an orderly plan together and  
order a tool rental with the parts.  Blau has a special on and  Chris  
at Force Five also can provide parts
and tool rentals.  Or, maybe you live close to a lister who has the  
tools?

Usually a timing belt change is just a chance to screw things up.  You  
change perfectly good parts in the hope you are preventing a failure  
during operation, but the only
feedback you get is if you don't change the water pump or an oil seal  
and it fails, or you do something wrong.  In this case you can see the  
added value of your work, but
the screw up part still applies.
