Preparation Steps
Before starting, ensure the vehicle is parked on a level surface and the engine is turned off. Wear safety gloves and goggles to protect yourself. Use a refrigerant recovery machine to safely remove the refrigerant from the AC system, preventing environmental harm and complying with safety regulations.
Removing the Old Receiver Drier

Recharging the AC System
1. Use a refrigerant recharge kit to add the correct amount of refrigerant as specified in your vehicle’s manual.
2. Start the engine and turn on the AC system to check for proper operation. Listen for leaks and verify cooling performance.
Final Checks and Cleanup
Ensure all connections are secure and there are no leaks. Lower the vehicle from the jack stands. Dispose of any recovered refrigerant responsibly and clean your tools.
Replacing the AC receiver drier can restore your Nissan Altima’s cooling efficiency. Follow these steps carefully for a safe and effective repair.
