Locating the AC Compressor
Before you can add oil to your AC compressor, it is crucial to know its exact location. The AC compressor can typically be identified as a silver metal cylinder with belts, tubes, and wiring attached to it. In most vehicles, you can find it on the left side near the front. However, if you’re having trouble locating it, you can refer to your owner’s manual or search online with the make and model of your vehicle for assistance in identifying the AC compressor’s specific position.
It is essential to park your vehicle on level ground and ensure that the engine is turned off before proceeding with any work on the AC compressor.
Preparing to Add Oil
Before you begin the process of adding oil to your AC compressor, it is important to take some safety precautions. These steps will help ensure that the process goes smoothly and without any mishaps.
First, make sure that the engine is turned off and the parking brake is engaged. This will prevent any accidental movement of the vehicle while you are working on the compressor.
Next, jack up the vehicle and remove the tire near the compressor. This will provide you with easier access to the compressor and make the process more manageable.
Once the tire is removed, you can proceed to remove the protective covering. Unscrew the mounting bolts that secure the covering in place and carefully remove it.
After removing the covering, you will need to loosen the nut on the belt and slide the belt off of the compressor. This will allow you to disconnect the wire connector from the compressor.
Finally, remove the pressure lines by unscrewing the bolts that hold them in place. Take care not to damage any other components while performing this step.
By following these precautions and steps, you will be properly prepared to add oil to your AC compressor and ensure that the process goes smoothly.
Capturing the Freon
Before adding oil to the AC compressor, it is necessary to capture the freon. This can be done using a reclaimer machine, which releases the pressure in the compressor and captures the freon so it doesn’t escape into the atmosphere.
Connect the reclaimer machine to the valves on the compressor and open the valves to release the freon. The freon will be stored in an internal tank on the reclaimer machine for later use. Reclaimer machines can be found at auto repair shops and typically cost between $400-$1,000.
Using a Reclaimer Machine
When capturing the freon from the AC compressor, it is important to use a reclaimer machine. This machine is specifically designed to safely remove and store the freon, preventing it from being released into the environment.
Here are the steps to using a reclaimer machine:
- Locate the valves on the AC compressor.
- Connect the hoses of the reclaimer machine to the valves.
- Open the valves to release the freon into the reclaimer machine.
- Monitor the pressure gauge on the reclaimer machine to ensure proper operation.
- Once the freon has been captured, close the valves and disconnect the hoses.
Using a reclaimer machine is essential for complying with environmental regulations and preventing the release of harmful refrigerants. It is a responsible and environmentally-friendly approach to AC compressor maintenance.

Draining and Refilling the Compressor
Once the freon has been captured, it’s time to drain and refill the compressor. Follow these steps to ensure a smooth process.
Step 1: Removing the Compressor
Start by unscrewing the mounting bolts that secure the compressor in place. Carefully remove the compressor from its location, taking extra caution to avoid any damage.
Step 2: Draining the Old Oil
Locate the rear cap of the compressor and remove it. Hold the compressor upside down to ensure that all the old oil drains out completely. Proper drainage is essential for optimal performance.
Tip: While draining the old oil, make sure to wear protective gloves and eyewear to prevent any contact with the oil.
Step 3: Determining the Amount and Type of Oil
Refer to your vehicle’s owner’s manual or consult the specifications for your make and model to determine the correct type and amount of oil required for your compressor.
Step 4: Refilling the Compressor
Using a funnel, add the recommended amount of oil into the compressor. Ensure that you pour the oil directly into the compressor and avoid spillage. Once the oil is added, securely fasten the rear cap.
| Manufacturer | Recommended Oil Type | Recommended Amount |
|---|---|---|
| Brand X | PAG 46 | 8 oz |
| Brand Y | POE 68 | 10 oz |
| Brand Z | PAO 68 | 12 oz |
Note: The table above provides general information for illustrative purposes only. Always refer to your vehicle’s specifications for accurate oil type and amount.
Step 5: Reinstalling the Compressor
Now that you have added the oil, it’s time to reinstall the compressor. Carefully position the compressor back into its original location and secure it with the mounting bolts.
Tip: When reinstalling the compressor, double-check that all connections are secure and properly tightened for optimal performance.
Step 6: Completing the Process
Once the compressor is securely in place, you can proceed with reconnecting the pressure lines and wire connector. Ensure that all connections are tight and secure.
Step 7: Verification
After completing the process, it’s essential to test your AC system thoroughly to ensure that it is functioning correctly. Switch on your air conditioning and monitor for any issues or irregularities.
By following these steps, you can effectively drain and refill your AC compressor, ensuring optimal performance of your air conditioning system.
Cycling the Compressor
After adding the oil, it is important to cycle the compressor to ensure that the oil is properly distributed. The cycling process helps to circulate the oil throughout the compressor, lubricating its internal components and promoting smooth operation. One effective method of cycling the compressor is by spinning the clutch plate, which is the black disk that rotates the shaft inside the compressor.
To perform the cycling process, hold the compressor in one hand and rotate the clutch plate several times. This motion helps to work the oil inside the compressor, allowing it to reach all the necessary areas for proper lubrication. By spinning the clutch plate, you facilitate the circulation of oil, reducing the risk of friction and wear on the compressor’s moving parts.
Remember, cycling the compressor is an essential step in maintaining the longevity and efficiency of your air conditioning system. It ensures that the oil is evenly distributed, providing adequate lubrication to prevent any potential damage or malfunction.
