KC250 who owned the 1st 3.0 EcoDiesel in Canada already commented on this. His friend Sean who also had the EcoDiesel diesel in the Gladiator had 456 regarding they both experienced the same overheating issues at the exact same time. They were at high elevations on a very steep grade deep grade he claims it was the hottest day he ever experienced. He had put thousands upon thousands of miles across Canada and through a good portion of the United States. He only experienced it one time but it forced him and his buddy SeanIs to a maximum speed of 40 miles an hour. I've never experienced it but in the event I'm in a extreme heat low density air situation like that I'd rather my engine degrade to prevent any serious engine damage or mechanical issues. This just recently happened case in point one of our fleet vehicles at work was pushed well beyond its capability because the payload was far exceeded. Not low density air situations but extreme heat on an extreme grade. The operator saw the temperature rising and and just pushed it anyway basically destroying the engine it's seized and hasn't run since.I really enjoy watching his videos and I have a bit of respect for Brad’s opinions, however, I do think he missed the mark on the diesel.
I’m fairly certain he never regeared, yes? Based on all the reading I’ve done here and other forums, it seems the folks on 37+ tires who regeared their diesels haven’t had issues with overheating. Perhaps if he’d been at, say, 4.10’s or even 4.56’s there wouldn’t have been an issue. I also think going WOT under load with a steep grade at altitude isn’t the greatest idea. We pull a fairly heavy TT with our F-350 6.0 diesel and I’ve always taken it easy up grades by running it at a higher RPM. Even over max weight when moving my wife out here from New Mexico, going up the mountains into Vegas in 110* heat.
I dunno. I realize it’s apples to oranges. I’ll be running 35’s on mine most likely, with a high probability of picking up a Patriot camper as well. Guess I’ll see if I have similar issues.
