Don.....I have had my starter on and off my van a dozen times in the past
year so I should know were the damn thing is.
As you stand and look into the engine bay the starter lies to the right of
centre behind the tinware. If you pull the tin towards you an inch or so
you will see the motor in behind. To take it off there are two nuts, the
upper one,(15mm I think) is located inside the engine bay and the other is
beside the motor so you have to get underneath for that. Remember to undo
the negative cable from the battery before you start any work on the
starter motor.

Good luck
