How to Remove a DPF Filter for Cleaning

Your trucks diesel particulate filter (DPS) collects soot from exhaust emissions and ash from motor oil. A significant amount of this material is burned off during normal operation. Still, some soot and ash will build up over time. That means your filter needs periodic cleaning or replacement.

How to Remove Your DPF Filter

These instructions are modeled after Ford and Volvo trucks. For other brands, check with your vehicle’s user guide or manufacturer to verify the details. It is vitally important that you make sure the engine is fully supported throughout the process.

  1. Remove the engine cover and intake piling
  2. Disconnect the O2 and EGT sensor plugs
  3. Remove the passenger side axle
  4. Remove the heat shielding around the DPF
  5. Jack up the vehicle
  6. Disconnect the V-band clamps on the exhaust system making sure to divide the two massive bolts on the DPF bracket

If you have done all of this correctly, you should now be able to remove the EGR filter. This is a good time to check your EGR, since it may also need to be cleaned or replaced.

  1. Remove the vital upper DPF brackets, removing plugs and setting wires aside
  2. Lower the front sub-frame if needed: if you lower the subframe it may change your alignment settings. You may need to have a wheel alignment done after replacing your DPF.
  3. While snaking your DPF out, try to rotate it 180 degrees to clear the steering rack. Do the same when re-installing it.

You should now be ready to clean or replace your DPF or perform a DPF filter cleaning.
