    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.

    Duralast belt 468k6 from auto zone will fit perfectly on the evolution.
    The first 3 numbers 468 is actually 46.8 inches, just fyi.
    I was using belt 453k6 and it wouldn't fit no matter what I did.
     
    mitmaks Thanks this.
