Problem Statement

Learn how to check for refrigerant leaks in the Ford Explorer (2020-present). Step-by-step diagnostic procedures and repair instructions included.

Affected Component

HVAC

Estimated Time

1-2 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical components.
•Ensure the AC system is fully depressurized before opening any parts.

Symptoms

•Air conditioning not blowing cold air
•Hissing or bubbling noise from the engine compartment
•Visible oil residue around AC components
•Frequent cycling of the AC compressor
•Refrigerant odor inside the vehicle

Diagnostic Steps

1
Examine all AC components (compressor, condenser, evaporator, hoses) for signs of oil or refrigerant leakage.
2
Add UV dye to the refrigerant system and use a UV light to identify leaks.
3
Use an electronic refrigerant leak detector to scan for leaks in the system.
4
Connect a manifold gauge set to measure the pressure in the AC system and check for drops over time.
5
Apply a soap solution to suspect areas and look for bubbles indicating a leak.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

•UV light
•Electronic refrigerant leak detector
•Manifold gauge set
•Soap solution (dish soap and water)

Parts Required

•UV dye (if not already in the system)

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery.

2. Visual Inspection

Inspect the AC compressor, condenser, and hoses for any visible signs of leakage.
Use a flashlight to check for any oil residue that may indicate a refrigerant leak.

3. UV Dye Test

Add an appropriate amount of UV dye into the AC system through the low-pressure service port.
Run the AC system for at least 10-15 minutes to circulate the dye.
Use a UV light to scan all AC components and look for glowing areas indicating leaks.

4. Electronic Leak Detector

Turn on the electronic leak detector and move the sensor around the AC components.
Listen for alerts from the device that indicate the presence of refrigerant.

5. Pressure Test

Connect a manifold gauge set to the low and high-pressure service ports.
Start the vehicle and run the AC on maximum.
Observe the pressure readings; if they drop significantly over time, this indicates a leak.

6. Soap Solution Test

Mix a small amount of dish soap with water in a spray bottle.
Spray the solution on all connections and suspected leak areas.
Look for bubbles forming, which would indicate escaping refrigerant.
