a/c bypass question
 

Im attempting to bypass my a/c compressor on my 2003 A6 2.7, all the forums i have found say to use a 64" belt, but i found that is for an s4 with no mechanical fan so 64" is too short. Does anyone know what length to use with mechanical fan?

So figured it out, if anyone is curious... its the same as a 2.8, i used a 69.5" 6 rib belt. 69.0" would be an ideal belt but 69.5" works.
