how to check the refrigerant levels in my Ford F-150 Fourteenth Generation (2021-present)

Solution

1. Preparation

• Tools Required: Manifold gauge set, safety goggles, gloves.
• Safety Warning: Ensure the vehicle is turned off and parked on a level surface. Wear safety goggles and gloves to protect from refrigerant exposure.

2. Locate Service Ports

• Identify the low-pressure port (typically on the larger diameter line) and high-pressure port (on the smaller diameter line) under the hood near the AC compressor.
• Clean the ports with a cloth to remove any debris or dirt.

3. Connect Manifold Gauge Set

• Attach the blue (low-pressure) hose from the manifold gauge to the low-pressure port.
• Attach the red (high-pressure) hose to the high-pressure port.
• Ensure the valves on the manifold gauge are closed before making connections.

4. Check Refrigerant Levels

• Start the engine and turn on the AC to the maximum setting.
• Open the low-pressure side valve on the manifold gauge and observe the reading.
• Check the high-pressure side by opening its valve and noting the reading.

5. Analyze Readings

• Compare the recorded pressure readings against the manufacturer's specifications for the ambient temperature.
• If levels are low, proceed to recharge the system as needed.
