Navistar N13

Diamond renewed also add in SCR I believe if it hasn't got it already. There are a 3 versions of N13. I can't remember exactly when the changes are but the N13A and N13B look exactly like a MF13. The N13B have an extra little coolant manifold on the side of the EGR cooler at the front. But, the EGR cooler and EGR valve are still the same as MF13 and still have same failure rates - 100%. SCR's do use less EGR, so those components do have an extended life span. Problem is, you are buying into this truck right when everything starts to go bad. I hope the Diamond Renewed comes with new DOC and DPF or I wouldn't even consider it. I not 100% sure what all gets done during the renewed process. I think it is mostly just updating the exhaust/aftertreatment. So again, if the EGR cooler and EGR valve are still original, I would expect to be replacing them within the next year.
FYI, N13C look like the new A26 with the all new EGR cooler and EGR valve.

 

I would make absolutely sure the EGR cores are replaced, along with the valve. That is great if they do. The difference between cleaning and replacing the DOC and DPF is about $7000. If the DOC has more than 8000 hours on it, I would want it replaced. Most of them start to degrade at about that time and become useless around 10,000-11,000 hours and need replacement anyway.

 

Switched from Cascadia to Diamond Renewed Prostar with N13 and have had no issues. Warranty is great and I like much better than my Freightliner

 

RUN! You are asking for trouble. I own a ProStar with the Cummins, CM-871. I fixed the motor, but have spent countless hours at my local International dealer. That is all they do, in frame those International motors and replace emission component$. There are always a few in there, there were three there this past weekend when I was getting parts, all being in framed.

 

Your truck will be considerably older with a different engine. You are comparing apples to oranges.

 

I spoke with more than a few of the mechanics...
