Right now the bypass is in use while I get the replacement parts etc. The thing that concerns me is that there is just enough of a difference of the pulley's position (compared to the compressor pulley) to stretch the belt to the absolute limit. I'm no engineer, but I'm wondering what kind of damage may result to other pulley shafts due to the abnormal stress. I could swear that when I plucked the serpentine belt, I could hear an E# note.

Worked well for when I was in a pinch on funds and compressor went out. Did have to use the supplied spacer for the pully for proper alignment.

It was a straight forward job. Remove AC compressor that was pooched and disconnect all electric and cooling connections. Install the bypass pulley to take the place of the AC compressor. I installed the original serpentine belt and good to go. Lots of good videos on inter web to aid in this install.

Worked like a charm after the ac compressor froze up and broke the belt. Pretty tough to remove the compressor but after I got it off the installation went smoothly.

This is listed fitting up to 2004 or so (I verified w/Dorman Tech Dept), but it comes with a big 5.3" pulley on it. It was listed for my 2003 Taurus, but the compressor only has a 4.5" pulley, so that means I either had to play games figuring out a belt length that would fit (for the life of the car), or replace the pulley on the bracket. I found a 38024 ACDelco/Gates pulley fit fine, and so the original belt fits, but the pulley cost me another $30 and wasted time.Just another perfect example of how Dorman thinks up great ideas, but manages to screw it up in the details/manufacturing.

So happy, it worked great to avoid an expensive repair on what is just an extra vehicle. Went in easily and worked out perfectly. Shipping was fast as always
