It’s more so body hurts and no I don’t know much about this system. But I know it’s work that I could do. I typically do all maintenance on my things.
Do you clean dpf filters from diesel cars?
Thank you for sharing this information, there’s so much info on the DPF system i always felt there wasn’t enough info on the actual SCR system outside of just discussing the fluid itself
Glad it was helpful!
I am curious why does that doser need to be replaced as opposed to just being cleaned?
Thanks for your efforts.any advice on wich scanner tools are good and if you can make a video on how to use a scanner and what to look for thanks again.
Can the decomposition tube be cleaned if it has a lot of build up from a bad def doser leaking?
What container do you usually use to perform a DEF doser test into?
Thank you 👍
You are welcome
Ryan can I mail you a ecm for a cm870 that goes in a international 9900? I got it off ebay to have as a spare ecm. "same cpl" When I plugged it in it idled fine however when I push the throttle the rpms go wide open. Something needs adjusted. Want to bench load it for around 600 hp useing a fleet calibration
How long can you drive with a code like this?
I've replaced my doser and it did not come with the gasket had to buy it separately
Thanks for the feedback, I guess some come with and some don’t. Just make sure to change the gasket as well
Where is your location, sir?
can the DOC be cleaned
Yes
Can I bring you the three "magic" pieces for cleaning 2 dpf's and a doc? and is the doc removable 2016 freightliner cascadia 1 box
@anthonytaranto5854 doc isn’t removable for 1 box. You will have to bring the whole one box to us for cleaning
Thank you how much for the cleaning?
@anthonytaranto5854 whole one box is $1200
You going to have a booth at truck show
Not a booth, going to walk around 😉
The dozer was the problem. The Nox was an unneeded extra expense for the customer.
Those nox sensor testers are not accurate at all
I had issues last night, paid $350.00 after one hour drive, and everything came back checked engine pdf light saying Stop ✋️ driving all of that filter full
Did is it soot out
If you put that Def nozzle in an ultra sonic cleaner and flushed it with gravity fed distilled water and pulsed the solenoid, I bet it would be just fine.
It sucks that an actual parked regen isn’t getting hot enough to actually burn fluid buildup away
Where u located in
Fox truck & tractor LLC 1120 high ave sw canton Ohio 44707
I keep getting code 3165 scr output temp 🤔
Def bs destroyed my last trk causing a fire. My new trk I jail broke the computer and removed the dpf no problems. Def Is a scam
It's always issues by someone else's hand
