Can you replace the serpentine belt on a 2000 Hyundai Sonata and by pass the ac compressor?

Yes you can. However, they do not make a specific serpentine belt for bypassing the ac compressor on a 99-01 Hyundai Sonata. You would have to measure the exact length you need to bypass the ac compressor. The belt would then go around the Power Steering, crankshaft, and alternator. The tension can be adjusted to fit this custom belt as well.
