Honda and 2006 Acura vehicles will receive a new receiver-drier anytime the compressor gets replaced. First, have a licensed AC professional take the old refrigerant from your system and store it safely. When taking the compressor out but keeping it working, turn it on for several minutes as you make your way to dumping the waste gas. Park the car, remove the drivebelt, set the parking brake, and block both rear wheels. Then lift the front of the car safely on jackstands. Remove and disconnect the electrical plug connecting the compressor clutch from its place on the fan shroud in front of the alternator. When lifting the subframe, set a floor jack under it on the right side, then eliminate the subframe mounting bracket at the bottom of the compressor while keeping note that the company says it's better to attach a brand new bolt when setting the subframe back in place. Close the refrigerator lines at the compressor and put cap covers on the open ends to keep dirt and moisture from getting inside. First take out the compressor mounting bolts, then pull it down. You'll see bolts holding the compressor mounting bracket, and you can take it off by first pulling out the bottom bolt of the lower alternator. Before putting it into place, you have to move the clutch from the old compressor to the new one. Follow the special instructions to check and adjust oil when installing a fresh or rebuilt compressor. Changing compression involves putting new O-rings in place on the compressor where the line fittings connect, tightening both subframe bracket and subframe mounting bolts. Reconnect the battery, then send the unit to the same shop that took the charge from it. They will reempty, recharge, and perform leak checks.
