Yes, they can.Ram can't be that stupid
How many DS trucks equipped with the HEMI and 8HP70 have you driven? I have seen plenty of evidence of cooking engines, both with the EcoDiesel and HEMI.I have not seen evidence that they are closed at high temps, just speculation.
You have an oil heat exchanger installed from the factory, not a cooler. The DT trucks are built and programmed differently. RAM never bothered to provide updates to correct the problem in DS trucks. I know, as I had a Tech Authority subscription, so I painstakingly checked every service bulletin and recall.I was going to get my mechanic to put in an oil cooler but apparently all 5th gens already come with heavy duty cooling as standard.
I can't wait to do it all over again. Maybe the @Wild one wants to join in.We've been through this extensively
