There’s no such thing as a good time for downtime, especially when it’s unexpected and not making you money. One issue many drivers don’t plan for is manual regenerations. If you haven’t experienced this issue yet, consider yourself lucky. A manual regeneration must be conducted when soot builds up inside the diesel particulate filter (DPF) to the point that the vehicle is no longer operable. When this happens, a driver must pull over and initiate a self-cleaning process that can take up to 40 minutes — valuable time that could have been spent on the road.
Below is an overview of manual regeneration, why a regeneration must be conducted, how often you should manually regenerate, and how to regenerate your truck.
What Is a Manual Regeneration & Why Must You Regenerate?
A self-cleaning process conducted the driver that must occur when exhaust soot builds up and overwhelms your DPF. A manual regeneration allows for better combustion, faster and more efficient fuel burn, and a dramatic reduction in soot. If you don’t consistently perform a manual regeneration your truck will become inoperable and cause a domino effect of problems.
How Often Should You Manual Regenerate Your Truck?
If your truck does not automatically regenerate itself, it is recommended to conduct a forced regeneration on a bi-weekly or monthly basis depending on the number of miles you’ve driven.
How To Regenerate Your Truck:
- Pull off the road into a parking lot where there is at least 5 feet of clearance from the exhaust or muffler.
- Set the parking brake with the engine running and transmission in neutral.
- Push the regeneration or manual regeneration button.
- The truck will run at high idle for 30-60 minutes (make sure you wait for the regeneration light on dash to go out).
- You may need to repeat the cycle.
If you’re unsure about performing your manual regeneration, you can hire any service shop to conduct it for you for a minimal fee. Questions or concerns? Refer to your truck’s owner’s manual.
