Funny how this thread, with 6000+ reads, is still alive after 10 months.
Just a theory, with no empirical evidence to back it up whatsoever, but I seriously doubt that Japanese who may have originally designed these subcompact tracts (orange, green, or red) with these types of transmissions and little cooling fans, never fully comprehended how North Americans were going to take these little diesel beasties and put them to tasks in places that would endanger them. In some cases, no design provision was even made for a quick or simple replacement of the broken little white plastic fan. This demonstrates the lack of understanding, comprehension or forward thinking envisioning of which I speak. They just didn't see this coming.
Now, those OEMs are "stuck" with designs that would be somewhat expensive to change. They've sold tens of thousands of these sub cuts, as is.
With the consumer feedback, I might expect a re-do and design change somewhere down the road, but it hasn't happened yet and I'm not holding my breath.
