Inspect the AC belt for any signs of fraying or cracks.
If damaged, remove the old belt by loosening the tensioner and replace it with a new OEM recommended belt.
Torque the tensioner bolt to the manufacturer's specifications.

4. Inspect and Test the AC Compressor

Tools Required: Manifold gauge set.
Connect the manifold gauge set to the AC service ports.
Check the operating pressure; if it is outside the normal range, the compressor may need replacement.
If the compressor is failing, proceed to replace it.
