I have a 2008 E60 550i, the a/c suddenly stopped working, I take a look at the ac compressor and its missing the belt, I go to turn the pulley and it wont move at all, after doing some research I figured it could be the ac compressor pulley, I have a local junk yard near me with a 2007 545i N62 4.4L I am wondering if I take the Pulley off the 545i and replace mine if the parts would be compatible? its starting to get near a hundred in Texas and hoping to get it working soon. The Texas heat is brutal.
