Navistar N13

Just curious, anyone have any real world experience with the latest Navistar N13 engines.

Not the Maxxforce, we all know about those, so don't want to rehash all the past nightmares. But wondering if the new SCR N13's are working out for International.

 

Knock on wood, so far not bad. I do see there are bulletins for bad liners causing oil consumption like Cummins had a couple years ago.

 

Thanks Heavyd. I was curious because I see some dealers around here are offering the longest best warranties I have ever seen on them. So they must have some confidence.

And you and I both know there is no longer such a thing as a bulletproof engine.

 

They got to use good bait to get people to look at them again.

 

You still really have to watch what you are buying. Early N13 with SCR still have the big EGR cooler and stupid egr valve at the back that caused a lot trouble the MF13 series had. Later N13 have a significantly smaller EGR cooler and valve that is actually made by Cummins. This is the series I recommend buying.

 

Is 2014 the start date for the N13? When did they change to the smaller egr, and can you retro fit it to the earlier N13 if need be, looking at a couple of trucks that run these motors and trying to get upto speed on them.

 

I think you are looking at 2015 engine years, so 2016 truck models for the updated cooler. No, you cannot upgrade older ones.

 

Hey guys,
Wanted to inquire a little more about the N13 SCR engines, in particular, the 430hp on the 2015 Prostar. From what i read, the 2015 engines on the 2016 Prostar has overall better design in terms of EGR cooler and what not. However, since the truck i'm considering is the 2015 Prostar(one with 400k miles), which is before that latest design, I am wondering if I could get 150k more out of it, if i'm nice to it. Now, the only reason i'm even considering it, aside from the low cost of ownership, is the 12 month (100K mile) Factory Warranty it comes with. By being nice to it, i mean:
1. Minimizing idling (would need APU to avoid it altogether.) I imagine when the truck is stationary, it must run hotter without the flow of air you get while cruising on the highway. And also, it seems idling might be rough on DPF?
2. Monitoring engine temp on hills and heavy loads and driving accordingly to keep it on the low side.
3. More regular service and maintenance.
4. In other words, driving it like the sensitive truck it is as opposed to riding it hard like it was one of those old school 500+ hp engines you could push to the edge.
Now, like many of you, i must have read 100's of posts with all kinds of horror stories, but its difficult to get any value out of such stories without the proper data around the situation: what year truck with what engine(hp rating)? how many miles on engine? how was it being driven? (i.e. cruising speed 62 or 72 MPH?) did driver idle? regular maintenance? average weight pulled? terrain?(i.e. flat or hilly?) etc...
Anyone with experience with the N13 SCR engines on the 2015 Prostar (430hp) who could provide some real data(positive and negative) would really be appreciated! You could save me and others from making a potentially disastrous decision and possibly help us make one that may improve our lives and the lives of our families. Thanks yall!

Best to all,
