Always for aftertreatment or engine only OEM. I doubt it is a problem with the aftermarket sensors now. But it was probably a misdiag for both to be bad after the repair. They were probably reading right just that Nox was out of the allowable limits. The code would allow you to see exactly what fault your Nox sensors were reporting bad. I would always run a Sublimation after replacing nox sensors just to clean out any DEF buildup in the SCR. there is sometimes a leaking DEF doser clogging the big pipe out of DPF into the SCR. This will throw the Nox readings off. May also throw off the DPF differentail pressure too. Also check wiring all around the DPF as there are a few places there that wires may rub. I have seen DEF pumps work fine when testing but when driving for hours they cause a problem.
I want to ask you, my pressure cup got crack right on the nipple between hose and insert nipple I want to replace the cup but hose is stuck twhat is best way to do it? I don't want to break hose that goes in. Maybe heat it up little?
Anyone found a solution? I already replaced compressor, egr cooler is good, took the head out replaced all the cups, even measured the linners put everything back up and still the same problem
Thank you for the video, I didn't think of replacing the small black plastic lines nor the zip tie trick. Thanks for the very helpful video.
You are the best man. So informative.
Man you always informative!
What do you think about steel or aluminum coolant tanks? Are they better?
Thanku very informative 👍
I appreciate you doing this!!!👊👊👊✌✌

Do you have to drain the coolant reservoir to change the expansion hose ?
best !!!

Thank you.
I have coolants pushIng out from overflow side do you know what can cause it
Hello, have you found the answer to your question, I have same issue
a few problems can do it, egr cooler, injector cups and cylinder head, and least common is air compressor
My is doing the same after changing reservoir. Replacing the cap to see what happens
Anyone found a solution? I already replaced compressor, egr cooler is good, took the head out replaced all the cups, even measured the linners put everything back up and still the same problem
@@Tampa-o8k my mechanic said might be thermostat stuck open and I actually got a code for that
Thanks, clips are a joke! Zip tied mine.
Same as Mack CHU/CXU tanks
