Any weight or drag on the engine, slows the engines response, and if you live in an area where AC is not needed, or if you just don't care, then with this belt you can bypass the pump, and still have the factory idlers, tensioners, and drive the water pump, alternator, power steering system.

Because the Caliber SRT-4 uses one long serpentine belt to drive all of the accessories, you cannot simply take off one belt to bypass the AC. You need a shorter belt that is the exact same width, and number of ribs.

We've done the research, measured, and tested this belt to bypass the AC compressor, and its worked well.

So, if you have removed the ac lines, compressor, etc already, or if you are going to just simply swap the belt for this one and leave the AC system in place to swap later, this works for you.
