When replacing the compressor on all 2001 and newer vehicles, you must also install a new accumulator/drier and orifice tube. Get started by emptying and refilling the air conditioner system. You should let a pro clean out the system when you need to replace the compressor. Unplug the black cable from your car battery and take off the air filter tube. First, pull off the electrical connector from the compressor, then loosen the part holding the wires behind it. First take off the drivebelt. Then disconnect the power steering reservoir from its mount and completely remove the reservoir holder. Block up the refrigerant pipes where they meet the compressor's back end, then cover the empty fitting openings to keep dirt and water from entering. On some cars, you need to take off the power steering lines that fasten to a bracket by the side of the compressor. Lift the compressor out by removing the mounting bolts from their brackets, and take note that the easiest way to access these bolts is by taking out the fenderwell access panel. Read and follow what the compressor maker tells you about removing oil from the old compressor before installing the new one. Take the dirty compressor oil out of the old compressor into a measuring container. Put the same amount of fresh oil, measured from the drained amount, into the new compressor. The clutch should be moved from the removed compressor and put onto the new one. When putting back an air cooling system, make sure to add fresh O-rings, and apply suitable oil designed for the system to all rings after reversing the uninstallation steps. The shop needs to both empty and refresh the system, then check for leaks.
