[s-cars] Special Tools--Timing Belt Replacement--UrS4

[Tom Green]

The dealer tool website will give you some insight for what the tools  
are as well as the best prices.  They are also available for rent from  
Chris Semple at force5.com in a kit for timing belt changes.  If you  
only plan to be doing this one vehicle, then tool ownership is not  
cost effective.  Where are you?  There are helpful list members that  
own tools.

You will see the 2079 spanner is 12" long with a 27MM socket and 3/4"  
fitting to accept a torque wrench.  It is used to reduce the torque  
wrench requirement to the commonly available 250 lb-ft
max setting.  (I know it is 258; If that is not good enough for you,  
get a bigger wrench.)  It also replaces the need for the big sockets  
if you don't have them.

The 3256 brace is really nice to have, and pretty much a requirement  
if you do not have a trusted helper or a really good flywheel holder  
instead.  It is such good insurance that the shafts don't move  
especially if you have to leave the area.  The bolt removal torque can  
be several magnitudes above the installation torque, so the lock is a  
real help there, and your helper can just make sure you don't turn the  
car over or slam the 6' pipe extension into the fender.  : )

The 3212 spanner that you use to hold the viscous fan pulley while you  
remove the fan and clutch is a piece of junk.  A better spanner might  
be useful, but instead of holding the pulley, I just put the 32MM thin  
wrench (3312) with extension on the nut at the back of the clutch  
while the belt is still in place and rap it with a hammer to impart an  
impact force to the nut.  I add pressure to the belt if necessary and  
this is usually enough to loosen the nut so it just spins off.  Some  
PB Blaster pre-treatment may help an older or very rusty nut.  It  
doesn't work every time and you can always remove the 4 small bolts  
holding the fan assembly to the clutch.  They can be reached after the  
lock carrier assembly is removed from the top of the radiator.

I am not sure my local dealer has that trick torque wrench (1331).  I  
just get a 250 lb-ft loaner from the  FLAPS tool loaner program and  
put a 1/2" to 3/4" adapter on it.  It is probably accurate within  
20%.  : )

The oil seal removal and installation tools are nice, especially if  
you have not manually done oil seals before.  With the radiator swung  
out, you have very good visibility to see the seal position
and insure you install it in the same position without damage so it is  
possible to do without them.
