The squeaking noise is almost certainly a problem *with* the AC compressor itself, not the belt routing. Here's why bypassing it is a bad idea and what to do instead:
* Belt Tension: The AC compressor contributes to the overall load on the serpentine belt. Removing it alters the tension, potentially leading to premature wear on the belt and other components. You'll need a new shorter belt, and ensuring proper tension will be tricky.
* Tensioner Damage: The tensioner is designed to work with a specific amount of belt tension. Removing the compressor may put excessive stress on the tensioner, potentially causing damage or premature failure.
* Potential for Damage to Other Components: Incorrect belt routing can lead to belt slippage, which can damage the alternator, power steering pump, or other components.
Instead of bypassing the system, troubleshoot the squeaking noise:
1. Check the AC Compressor Clutch: The most likely culprit is the AC compressor clutch. It's the part that engages and disengages the compressor. A squeaking sound often indicates a worn or failing clutch bearing. This is often a simple and inexpensive fix (replacement clutch or compressor).
2. Check the Belt: Examine the serpentine belt for cracks, fraying, or glazing. A worn belt can squeak.
3. Check the Belt Tension: Ensure the belt is properly tensioned. A loose belt can squeak. (Use a tension gauge for accurate measurement if possible).
4. Lubricate (Temporarily): As a temporary measure, you can *carefully* spray a small amount of belt dressing (NOT WD-40!) on the belt while the engine is OFF. This is a temporary fix and should be followed by a proper diagnosis and repair.
In short: Fixing the squeaking AC compressor is far easier, safer, and more reliable than attempting to bypass it. Take your car to a mechanic specializing in AC repair or a general auto repair shop for proper diagnosis and repair. The cost of repairing the AC compressor will be far less than the potential damage caused by improperly bypassing the system.
