How to Put Freon in a 2015 GMC Acadia

For those who own a 2015 GMC Acadia, this article provides a step-by-step guide to replenishing your car’s Freon levels. By following these steps carefully, you can ensure the optimum cooling performance of your vehicle and enhance your driving comfort.

Steps to Recharge the 2015 GMC Acadia with Freon

  1. Safety Precautions
    • Always wear safety glasses and gloves.
    • Ensure the vehicle is on a flat surface and the engine is off.
  2. Locate the Low-Pressure Port
    • Open the hood of your 2015 GMC Acadia.
    • Find the low-pressure port on the passenger side near the firewall. It’s covered by a cap marked ‘L’ or ‘LOW’.
  3. Check the Current Freon Level
    • Using an AC gauge, connect it to the low-pressure port.
    • Turn on your vehicle and set the AC to the maximum level.
    • Observe the reading on the gauge. It indicates that a recharge is necessary if it’s below the recommended level.
  4. Recharge the System
    • Attach the Freon recharge kit hose to the low-pressure port.
    • Begin releasing the Freon into the system. It’s essential to rotate the can from the 12 o’clock to 3 o’clock position every few seconds to ensure effective charging.
    • Monitor the gauge and stop when it reaches the appropriate levels.
  5. Test the System
    • Turn on the AC system and feel the air. If it’s cooler, the recharge was successful.
    • If not, there may be a larger issue at play, such as a leak or a malfunctioning component.
  6. Seal and Disconnect
    • Once the recharge is successful, remove the Freon recharge kit hose.
    • Seal the low-pressure port by reattaching the cap.

Possible Signs Your 2015 GMC Acadia Needs a Freon Recharge

  • Reduced Cooling: If the air produced by your vehicle’s AC isn’t as cold as it once was, it’s a clear sign of low Freon levels.
  • AC Clutch Doesn’t Engage: When the AC system is turned on, and the clutch doesn’t engage (the center of the pulley isn’t spinning), it can indicate insufficient Freon.
  • Visible Leaks: Any visible sign of refrigerant leakage in your vehicle should be addressed immediately.


Maintaining the air conditioning system in your 2015 GMC Acadia ensures a comfortable driving experience, especially during the hotter months. Regularly checking and replenishing the Freon levels when needed can extend the life of your AC system and offer optimum cooling performance. Following the steps outlined in this guide, you can efficiently and safely recharge your vehicle’s Freon. However, always consult with a professional if you’re unsure or the problem persists.
