1. Gather your tools and materials:
a) New compressor oil (check your vehicle's owner's manual for the recommended type and amount)
b) Oil injector (a specialized tool used to inject oil into the AC compressor)
c) Safety goggles
d) Gloves
e) Funnel
2. Prepare your vehicle:
a) Park your vehicle on a level surface, turn off the engine, and allow it to cool down.
b) Engage the parking brake.
3. Locate the AC compressor:
a) Open the hood of your vehicle and locate the AC compressor.
b) It's usually a cylindrical or rectangular-shaped component with multiple lines connected to it.
4. Connect the oil injector:
a) Remove the plastic cap from the oil injector port on the AC compressor.
b) Connect the oil injector to the port by screwing it in securely.
5. Add the compressor oil:
a) Insert the funnel into the oil injector opening.
b) Pour the recommended amount of compressor oil slowly through the funnel.
6. Disconnect the oil injector:
a) Once you've added the correct amount of oil, disconnect the oil injector from the compressor.
b) Reinstall the plastic cap on the oil injector port.
7. Start the engine:
a) Start the engine and allow it to run for a few minutes.
b) This will circulate the new oil throughout the AC system.
8. Check for leaks:
a) Visually inspect the compressor and AC lines for any signs of leaks.
b) If you notice any leaks, you may need to add more oil or repair the leak.
9. Enjoy your cooling AC:
a) Your AC should now be properly lubricated and ready to use.
b) Test it by turning on the AC and checking for cool air.
Note: Adding compressor oil to your AC system can be a delicate process, especially if your vehicle has a modern AC system with R134a refrigerant. If you're not comfortable performing this task yourself, it's best to have it done by a professional mechanic.
