A lot of people are still asking questions about Navistar DPF, or are doubtful if this is really the right DPF for them. That’s why today we will also help you answer a few questions commonly asked by customers.

Let’s check this out!

What does a DPF look like?
A DPF is not a spin-on type filter like an oil filter or a cartridge-type like a fuel filter. The ceramic filter itself, about the size of a five-gallon bucket, sits in a metal canister that also acts as a collection device for soot. The DPF is found downstream from the engine in the exhaust system

When the DPF starts clogging up, does it impacts my vehicle’s performance?
Much like a clogged catalytic converter on your car, a plugged DPF interferes with efficient exhaust flow. It can lead to compression or combustion problems if left untreated. In most cases, the DPF burns off the accumulated soot through either a “passive” or “active” regeneration.

How long does its cleaning would take?
There are two types of cleanings and both need to be done by a certified DPF technician. If you need to change out the DPF – usually because it is chipped, cracked, burned or melted – it takes about 2.5 hours, depending on vehicle or engine make. If your DPF is in good shape and just needs to be cleaned, you’re probably looking at four to five hours.
