just remember the belt should be tensioned to 95lbs of deflection force or more simply .25" deflection at the middle of the longest span of the belt. Too tight and you will fry the alternator bearing and too loose and you will get a squeal when the compressor engages. this applies to the non idler equipped apu only.
