DEF Dosing Valve Replacement: Kenworth/Peterbilt

[@skojak7814]

Thanks for the video you just saved me a roadside tow and 3 weeks without a tractor. Sitting in a Pilot on a full DERATE because of a DEF sensor error. Road squad was useless! I pulled my doser valve sprayed it with brake cleaner to clean it and I was back on the road in 45 minutes. Couldn't have done it without you 👌

[@KoonTrucking]

Heck yeah !

Check out our playlists truck fixing, we have tons of videos

[@SlackTastic]

Thanks gentlemen. You forgot to mention washing off any metal surface the DEF spills on ASAP. That stuff will damage/ etch metal real quick. Especially aluminum.

[@leelavinder2231]

Hey Mr. Koon I’m wanting to learn more about wiring, wiring diagnostics, and fixes. I believe I’ve seen you mention you enjoy that. What do you have to teach me and other viewers? Tips, Tricks, lessons, and theory? Thank you for whatever you can share. Long time viewer, seldom commenter. 😃

[@Outdoors.with.Ricky_P]

Thanks for all the videos you put out. I have a 2014 T680 mx13 and I have been told this valve is stuck open and I have def leaking from the front pipe. It looks like this valve is the underside of the truck. If I try to replace myself do I need to have someone with a laptop do anything with the ECM after it's installed. Currently no check engine light or lights on.

[@KoonTrucking]

If you don’t have a check engine you shouldn’t especially if it isn’t giving a problem.

[@KoonTrucking]

You should look in the OTR performance deals. I have a video on it. They are amazing. Always you to clear codes and force a regen and get your truck out of derate modes without spending $4000 on a scan tool. With it and a cheap code reader it can allow you to save thousands of dollars on repairs and be able to avoid high dollar tow bills due to derate kzbin.info/www/bejne/pWKTm32PmsqNa5I

[@Outdoors.with.Ricky_P]

Thanks for your advice. I will do that. I'm very limited on repairs I can do for physical reasons. Your repair videos and tips help a lot.

[@Outdoors.with.Ricky_P]

[@kevinwhite5665]

Thanks I find the videos very informative, and it will save me a lot of money.

[@TheTheomax]

I see you hit 10,000 subs I'm sure that took a lot of work on your end. It's really nice to see the Koon trucking channel grow.

[@Rexzxv]

If you can tell when we have to change the part,and which the issue for it ,thank you for your help

[@kozakvod]

This is a good video but I am curious why did you not inspect the DECOMP tube for crystallized DEF inside? You didn't mention anything about it so I was curious.

[@mjbalderas70]

Great video. At how many miles you recommend to change it? Thank you

[@grintechnology9643]

Does cleaning help? Do you have to remove def feeder hose and radiator hoses before pulling doser to just clean?

[@danf6975]

Is the doser valve for a 2014 Paccar (t680) in the same position or is it underneath? Every three weeks I keep getting poor DEF quality and take it into the shop and nobody after tens of thousands of dollars has been able to fix the problem and now I am $34,000 in repairs on this truck I’ve had for seven months and I’m sitting in front of a Kenworth right now waiting for them to open

[@Mike_Greentea]

Which location is that so we can avoid it!

[@bobbygarrett9588]

Great Video, Just replaced one myself yesterday on a 2014 Peterbilt with the Pac Car.

[@steveconner7354]

How do you get the hoses off the diesel Exhaust fluid injector I know it’s simple, but I can’t figure it out

[@exportconnections6655]

Thanks i couldn’t figure out how to remove the hoses. My doser now cost $700 in California 😢

What are the hose crimping tools called. Nifty stuff!!

[@edwinsuarez6264]

How did you go about diagnosing? Not sure if i have a bad fuel dosing module or dosing valve.

[@berniesands6201]

Do you need to unhook the truck batteries when you do this job?

[@alross18058]

whats the general life expectancy of the doser valve and should you change it as a pm item at a certain interval to avoid on the road probles or just wait until they take a shit

[@TheFerfast]

Thanks for the all information

[@UnderPsi5.0]

I have a 2017 579 with the mx13 I’m getting a spn-4364 scr 1 after treatment conversion efficiency. Could this doser be the culprit

[@pedropedro2837]

Thanks you

[@coach2208]

Can the doser value cause exhaust like fumes into the cab if it's a bad valve.

[@Davirokr]

Did you need to plug it into a computer after you were done to clear any codes

[@KoonTrucking]

Yes or to force a regen to disable a derate

[@FULLSCALEDISCOVERIES]

Wondering what codes you had

[@kelvincruz3889]

I own a 2016 W9L with the ISX...when it gets cold down to 20s Im getting a red light on the def gage kind of like when you don't have any left in tank...then it shows the service now 2hrs before 40% derate thing kicks in...any ideas or have you ever come across with this?thank you

[@cookiesmom8398]

Are these the same part numbers needed for a 2014 t680?

[@MrKeithsmith943]

What if the screws break, the stainless 3 screws?

[@jtdehoyos]

Where can i get one of those blue handle clamping pliers???

[@conquest7563]

Was the valve bad or just needed to be cleaned?

[@KoonTrucking]

Those dosing valves are all junk. Def fluid is super corrosive and it is just a bad idea. It will never work without constant repair costs.

We change our filters one time a year for PM sometimes more depending on mileage. But usually just when the dosing valves go bad change them

I don't think mine had water going to it mine is a 2019.🤔

[@TellNoL437]

Use hose clamping tools like that in some shops and they run you off. The reason, it weakens the hoses and makes them crack/burst when hot. Be sure to see your shop policies before using them. My dealer will fire you on the spot.

[@willmann30]

That's why shop fees are insane. In order to do this either you'll drain the system or take off the the doser with hoses attached then install the new doser. With a second person quickly disconnect and connect the lines on the new doser. Crack the reservoir to release any pressure beforehand. Penske former tech here!

[@North49trucker]

I think my 389 has stopped using def. this must be why

[@harloveleensandhu9061]

Hey I am facing a strange problem with def system of paccar mx13. Went to several mechanics and dealers. Spent a lot of money but cant find the problem. Truck shows a fmi18 spn 4364 and when we connect tool it shows aftertreatment 1 outlet O2, data drifted high. So first dealer changed my O2 sensir and cleared the codes. After driving it for 800 miles the light came up again with same codes . Same thing showed up on davis. So the this dealer changed my doser and cleard the codes. After driving for 800 miles the code came on again . What do you suggest ? I got new dpf filters in there too by some mechanic.

Could be a wiring harness issue ?

What ENGINE. The make and model of truck doesn't matter when it comes to the ENGINE.
