how can I tell if my Honda Accord has a refrigerant leak

Solution

1. Preparation

• Gather tools and materials: A/C leak detection dye, UV light, manifold gauge set, gloves, safety glasses.
• Ensure the vehicle is parked on a level surface and the engine is cool.

2. Add A/C Leak Detection Dye

• Locate the A/C low-pressure service port on the vehicle.
• Clean the port with a cloth to prevent contamination.
• Connect the A/C dye injector to the low-pressure service port and inject the recommended amount of dye.
• Reconnect the service port cap securely.

3. Conduct A/C System Pressure Test

• Attach the manifold gauge set to the A/C service ports (low and high).
• Start the engine and turn on the A/C to the maximum setting.
• Observe the pressure readings on the gauges; compare with the manufacturer's specifications.
• If the readings are low, it indicates a potential refrigerant leak.

4. Inspect for Leaks Using UV Light

• After running the A/C system for 15-20 minutes, use the UV light to inspect the A/C components.
• Look for any glowing spots, indicating the presence of the leak detection dye.
• Identify and mark the leak areas for repair.

5. Repair or Replace Damaged Components

• If leaks are found in hoses or seals, replace the affected components.
• Ensure all connections are tight and secure.
• Recharge the A/C system with the appropriate refrigerant type and quantity.
