Aftertreatment

Diesel Exhaust Aftertreatment

Aftertreatment systems are essential for reducing the amount of harmful NOx and particulate matter that enters the atmosphere. Lack of proper maintenance can lead to inaccurate sensor readings and costly repairs down the line, so it’s important to stay alert when it comes to caring for your engine.
 

    How to Prevent Expensive Repairs

    Maintaining your aftertreatment system is one of the most critical parts of keeping your truck on the road. Here are some tips to keep yours in top shape:

    • Change the DEF filter after every 100,000 miles
    • A professional should perform preventative maintenance on your truck monthly
    • Keep a close eye out for the warning signs listed above. Catching them early on can save you a lot of money and reduce downtime.
    • Do not ignore when you have a check engine light related to aftertreatment. Instead, have the problem diagnosed and repaired by a professional. Turning a blind eye to your check engine lights will always lead to more significant and costly issues.

    Signs Your Aftertreatment System Needs Repairs (Before the Engine Light Comes on)
