How do you replace the tensenioner pully on the serpentine belt. There seems to be a bolt and nut that hold it on that I cannot reach.

DRIVE BELT AUTO-TENSIONER
Inspection
Check whether there is a change in the position of the auto-tensioner indicator before starting the engine and after starting the engine. If there is a change in the position, replace the auto-tensioner. See Fig. 2 .
Check for abnormal noise from the tensioner pulley. If abnormal noise is heard, replace the tensioner pulley.
Remove the drive belt. See DRIVE BELT .
Move the auto-tensioner within its limit with the belt tension release tool in the direction shown. See Fig. 14 . Check that the tensioner moves smoothly and without any abnormal noise. If the tensioner does not move smoothly or there is abnormal noise, replace the auto-tensioner.
Remove the auto-tensioner. See REPLACEMENT .
Install the tensioner pulley.
Clamp the auto-tensioner "A" by using two 8 mm bolts "B" and a vise "C". Do not clamp the auto-tensioner itself. See Fig. 15 .
Set the torque wrench "D" on the pulley bolt.
NOTE:If the indicator exceeds the center mark, recheck the torque.

Align the indicator "E" on the tensioner arm with center mark "F" on the tensioner base by using the torque wrench, and measure the torque. If the torque value of 20-36 ft.lbs (27-36 N.m) is out of specification, replace the auto-tensioner.
