They have automatic tensioners. If the belt needs adjustment, either you have a bad tensioner or a worn belt.
Replace belt self tensioner, if applicable. Adjust belt tension. Replace belt. Have ac pressures checked. AC compressor may be failing.
you dont adjust a tension pulley you adjust the position of the compressor to tighten the belt
remove bottom skid plate and find ac belt and find ac belt tensioner and loosen center bolt and screw in long bolt to tighten,then tighten lock nut.

To change the AC compressor clutch on a 2001 Peterbilt, first, disconnect the battery and remove the serpentine belt from the AC compressor. Next, remove the compressor from its mounting bracket to access the clutch assembly. Use a puller tool to detach the clutch from the compressor shaft, then install the new clutch by reversing the removal process. Finally, reassemble everything, reconnect the battery, and check the AC system for proper operation.
You have to use the same belt and install a dummy pulley kit in place of the ac compressor.
You may need to adjust your belts, check the ac belt first.
order a belt for one without ac. Idid this on my 98 neon
You move the AC compressor and the alternator to adjust tension. Has to be done from under car.
To adjust the AC and power steering (PS) belt on a Mazda MX-3, first, locate the tensioner pulley for the belt. Loosen the tensioner bolt, then adjust the tension by either moving the tensioner or adjusting the mounting bolts of the components. The belt should have about half an inch of deflection when pressed firmly in the middle; readjust and tighten the bolts once the correct tension is achieved. Always refer to the vehicle’s service manual for specific torque specifications and procedures.
It could be a lose or broken belt. The same belt drives the AC and the alternator.
