why is my Honda Pilot YF3 (2016-2022) leaking refrigerant?

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the vehicle's battery (negative terminal).
• Ensure the vehicle is parked on a level surface and the engine is cool.

2. Locate the Leak

• Use an electronic leak detector to trace refrigerant leaks.
• If a leak is detected, mark the location for repair.

3. Replace Damaged Components

• If the refrigerant leak is found in hoses or seals:
  • Tools Required: Wrench set, hose removal tool.
  • Sub-steps:
    1. Remove the affected hose or component using the wrench.
    2. Install the new hose or seal, ensuring proper alignment.
    3. Torque fittings to manufacturer specifications (usually around 15-25 ft-lbs).

4. Recharge the AC System

• Tools Required: AC refrigerant recovery machine, refrigerant gauge set.
• Sub-steps:
  1. Connect the refrigerant gauge set to the service ports.
  2. Recover any remaining refrigerant in the system.
  3. Vacuum the system to remove moisture (typically for 30 minutes).
  4. Recharge the system with the correct amount of refrigerant (usually around 26-30 ounces for the Honda Pilot).

5. Final Checks

• Inspect all connections for leaks using the electronic leak detector.
• Reconnect the battery and start the engine.
• Turn on the AC to check for proper cooling performance.
