Learn the essential steps for effectively cleaning a contaminated diesel aftertreatment system, ensuring optimal performance, fuel efficiency, and emissions compliance.
Welcome to the Aftermarket DPF, comprehensive Step-by-Step Guide to Cleaning Contaminated Diesel Aftertreatment Systems. Designed to help you tackle common issues affecting your engine's performance and emissions, this guide offers clear, easy-to-follow instructions for identifying and addressing various types of contamination impacting your Diesel Particulate Filter (DPF), Diesel Oxidation Catalyst (DOC), and Selective Catalytic Reduction (SCR) systems.
By following this guide, you'll be well-equipped to restore your aftertreatment system's efficiency and extend its lifespan, ensuring a cleaner, more reliable, and environmentally friendly driving experience. Let's dive in and learn how to maintain your diesel engine and aftertreatment system like a pro!
Determine the type of contamination affecting your diesel aftertreatment system, such as coolant, fuel, or oil contamination. This will help you target the specific components requiring attention.
Before cleaning, make sure the engine is cool to avoid injury. Disconnect the battery, and follow any manufacturer-specific procedures for preparing the system for maintenance.
Carefully remove the affected components, such as the Diesel Particulate Filter (DPF), Diesel Oxidation Catalyst (DOC), and Selective Catalytic Reduction (SCR) system. Be cautious not to damage any sensors or connections during the removal process.
If horizontal or vertical cracking or melting occur, then a full replacement of the DOC, DPF and SCR filter system is in order. Possible surface cracking can occur that may not continue throughout resulting in a yellow tagged filter. Additional testing is performed to determine if internal melting or cracking has occurred.*
*Yellow tagged filters show signs of wear and potential signs of failure. In the event your filter is tagged yellow, please consult with your cleaner on your options.
Depending on the type of contamination, employ appropriate cleaning methods and solutions for each component. This may involve:
Always follow the manufacturer's guidelines and recommendations for cleaning.
The most common method for filter cleaning is thermal cleaning. This cleaning uses heat to burn away soot from the filter. For a more thorough deep clean, you can use a blast cabinet with compressed air and vacuum technology, LIKE US!
While DIY methods such as water pressure washing may seem like a viable option, they carry a significant risk of filter damage and should be avoided unless you possess adequate experience. If you choose to proceed with this approach, ensure that the filter is allowed to dry for a minimum of 10 hours before re-installation to prevent potential complications.
Once all contaminants, including oil, fuel, and coolant, have been thoroughly removed from the system, proceed to sanitize the exhaust system piping from the turbocharger to the point where it connects with the Diesel Oxidation Catalyst (DOC) filter.
Ensure that all temperature and pressure sensors are cleaned using an electrical cleaner, and verify the validity of NOx PPM sensor readings to achieve optimal Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) performance. Be aware that NOx sensors may require replacement due to contamination.
After cleaning, inspect the components for any signs of damage or wear. If any parts are beyond repair, replace them with new or re-manufactured components that meet OEM specifications.

Carefully reassemble the aftertreatment system, ensuring all components, sensors, and connections are properly secured. Reconnect the battery and any other disconnected systems.
Once reassembled, start the engine and monitor its performance. Begin by starting the engine and allowing it to run at idle or high idle for 1 to 3 hours without producing any smoke. During this period, ensure your vehicle is parked outdoors, allowing exhaust gases and any potential smoke plumes to dissipate into the atmosphere.
Next, verify that the regeneration system is functioning properly. This step will require the use of an advanced diagnostic tool. If any fault codes persist during the DPF regeneration process, identify and replace the affected components before restarting the procedure. In some instances, performing two consecutive regeneration's may be advised to achieve the optimal temperatures needed to combat contamination.
Following our Step-by-Step Guide to Cleaning Diesel Aftertreatment Systems empowers you to effectively address common issues and restore your engine's performance, fuel efficiency, and emissions compliance. By taking a proactive approach to maintaining your Diesel Particulate Filter (DPF), Diesel Oxidation Catalyst (DOC), and Selective Catalytic Reduction (SCR) systems, you can extend the life of your engine and its components, ensuring a cleaner, more reliable, and eco-friendly driving experience.
Remember, regular inspection and maintenance are key to getting the most out of your diesel engine. For all your aftertreatment system needs, trust Aftermarket DPF to provide top-quality products and exceptional filter cleaning service, keeping your diesel engine running smoothly for years to come.
