Before You Start: Gather the Necessary Tools
Before you start the process of removing the AC compressor, it’s important to gather all the necessary tools. These include a set of hand tools like wrenches to loosen bolts and nuts, screwdrivers to disconnect wiring harnesses, and pliers to remove retaining clips.
In addition, you’ll need safety glasses and gloves for your protection. Most importantly, due to environmental and safety regulations, you’ll need a refrigerant recovery machine to safely remove and store the refrigerant from the AC system. These machines can be rented from many auto parts stores.
Step 1: Discharge and Recover the Refrigerant
Discharging and recovering the refrigerant is the first step in the process. Refrigerant is a hazardous substance and should be handled with care.
Begin by attaching the hoses from your refrigerant recovery machine to the service ports on your AC system. These are typically capped tubes located on the AC lines in your engine bay.
Follow the instructions provided with your machine to safely recover the refrigerant from the system.
Step 2: Disconnect the AC Compressor
After safely discharging the refrigerant, the next step is to disconnect the AC compressor from the rest of the system.
Begin by using your wrench to loosen the belt tensioner and remove the belt from the compressor pulley.
Next, find the electrical connector attached to the compressor, it’s typically a plug-type connector.
Unplug this by pressing on the retaining clip and pulling it out.

Step 3: Remove the AC Compressor
Now that the AC compressor is disconnected, you can remove it.
Start by using your wrench to unfasten the bolts that secure the compressor to the engine. There are usually 3-4 bolts, depending on the model of your vehicle. Keep these bolts in a safe place as you’ll need them to install the new compressor.
Once the bolts are loose, lift the compressor out of its seating, but be careful as it can be quite heavy.
Step 4: Preparation for Installation of New Compressor
Before installing a new compressor, it’s important to clean the area where the old one was located. Any dust or debris can potentially damage your new compressor.
Use a cloth or a small brush to clean the area. Make sure to also inspect the AC lines and electrical connections for any signs of damage.
