Yup - do it.  It's due under the five-year rule.

Yes, it's quite similar to the RR.  You need #2084.  #2079 is optional -
it's only any use if the car is on a ramp.  I prefer to use a monster torque
wrench.

I think I've had the _opposite_ - I found a car last year with a
phenomenally tight belt and the pump bearings were shot.
