A/C Compressor Pulley Guides

AC Bypass Pulley: How to Install When AC Compressor Goes Bad

The AC bypass pulley is used to replace the AC compressor when it goes bad. The AC bypass pulley is also more affordable than a replacement AC compressor. Below is a guide on how to properly install an AC bypass pulley when your AC compressor became faulty.

Difficulty level:Moderate

Things you'll need:

  • Socket set
  • Ratchet set
  • Pen
  • Paper
  • Line wrench set
  • Belt tensioner tool

Step 1: Before starting this DIY, remember to visit your local shop, and let a professional mechanic remove any remaining Freon from the system.

Step 2: Make sure to have all the tools and materials needed to avoid hassle in the middle of the process.

Step 3: Now, carefully lift up the hood, and use your factory installed prop rod to support the hood.

Step 4: With a pen and paper, sketch the estimated location of each pulley, and how the belt wraps around those pulleys.

Step 5: Carefully affix the belt tensioner tool into the matching fitting on the belt tensioner.

Step 6: You need to rotate the belt tensioner tool in order to release the tension on the belt. Make sure to do this carefully.

Step 7: Remove the tension away from each pulley. Set it aside.

Step 8: Before removing the belt tensioner tool, make certain that the tensioner rests in its natural position first.

Step 9: Using your line wrench set, locate and remove the two lines that link into the AC compressor. Just follow the lines back to their other connecting points.

Step 10: You need to locate the AC compressor mounting bolts, and loosen them using your socket and ratchet set. To do this, carefully support the AC compressor with one hand, then remove the mounting bolts with your other hand. After that, set the old AC compressor aside.

Step 11:Now, carefully line up your AC bypass pulley mounting holes with the holes that were used for the AC compressor before.

Step 12: Install the mounting bolts by hand.

Step 13: Then, tighten the bolts using your socket and ratchet set.

Step 14: Check if the serpentine belt has cracks or damage. You need to replace the belt if necessary.

Step 15: Route the belt around the pulley system carefully. Use the sketched routing diagram that you have drawn earlier. Remember that the belt should rest loosely around all the pulleys except for the tensioner pulley.

Step 16: Affix the belt tensioner tool into the belt tensioner. Apply a pressure and rotate the belt tensioner.

Step 17: After that, gently slide the serpentine belt directly under the belt tensioner.

Step 18: Release the pressure slowly on the belt tensioner tool until it sits on the belt and draws the belt tightly secured around the pulley system.

Step 19: Now, remove the belt tensioner tool from the belt tensioner, and you're done.

Always keep in mind that when routing the serpentine belt, you should always start with the harmonic balancer, and work towards the top of the engine. Also, you are not allowed to start your engine without installing the serpentine belt. We always recommend DIYers like you to refer to your vehicle's manual for detailed information on how your auto parts work, and watch online videos to avoid mistakes.
