How to remove Crystallised Adblu

Introduction

This tutorial provides a step-by-step guide on how to effectively remove crystallized AdBlue from your vehicle. AdBlue, a diesel exhaust fluid, can crystallize and cause blockages if not managed properly. Knowing how to remove these crystals can help maintain your vehicle's performance and avoid costly repairs.

Step 1: Identify the Issue

• Check for warning lights on your dashboard indicating AdBlue system problems.
• Inspect the AdBlue tank and surrounding areas for visible crystallization.
• Look for any signs of damage or blockages in the AdBlue lines.

Step 2: Prepare Your Tools

Gather the necessary tools and materials to safely tackle the crystallization:

• A suitable container or bucket for draining AdBlue.
• Protective gloves and goggles to ensure safety.
• A soft brush or scraper to remove the crystals.
• A funnel for refilling AdBlue if needed.

Step 3: Drain the AdBlue Tank

• Locate the AdBlue tank, usually found near the diesel filler cap.
• Using the container, carefully drain the AdBlue fluid from the tank.
• Be cautious not to spill any fluid, as it can be harmful to the environment.

Step 4: Remove Crystallized AdBlue

• Use the soft brush or scraper to gently remove any crystallized material from the tank and lines.
• Take your time to avoid damaging the tank or any components.
• Ensure all visible crystals are cleared before proceeding.

Step 5: Clean the System

• Rinse the tank and lines with clean water to remove any remaining crystallized residue.
• Use the funnel to pour clean water into the tank, swishing it around to aid in the cleaning process.
• Drain the water completely before moving on to the next step.

Step 6: Refill with Fresh AdBlue

• Once the system is clean and dry, refill the AdBlue tank with fresh AdBlue fluid.
• Follow the manufacturer's specifications for the correct type and amount of AdBlue to use.
• Secure the tank cap properly after refilling.

Step 7: Test the System

• Start your vehicle and monitor the dashboard for any warning lights.
• Check the performance of the AdBlue system to ensure it is functioning correctly.
• Take the vehicle for a short drive to confirm everything is running smoothly.

Conclusion

Removing crystallized AdBlue is crucial for maintaining your vehicle's efficiency and performance. By following these steps, you can clean the system and avoid future crystallization issues. Remember to regularly check your AdBlue levels and keep an eye out for any signs of crystallization to prevent complications. If problems persist, consider consulting a professional mechanic for assistance.
