The technician must decide whether or not these cracks are serious enough to impair belt performance, requiring belt replacement. If any sections of the belt are missing, the belt should be replaced immediately.

Checking Drive Belt Tension:





2. Check the compressor drive belt tension using thumb pressure and adjust if necessary to specification.
3. To adjust belt tension, loosen compressor mounting bolts and repositioning compressor along the upper mounting bracket axis.
