Unique coolant temp question?
When I was leaving for work this morning, driving on normal, 50 mph roads, my EOT was about 192 and my ECT was 188. As soon as I got on the highway and got up to about 75 mph, my EOT stayed relatively the same, but my ECT dropped to 182 for just about the whole 7 mile ride to my exit. As soon as I got off the highway and dropped back down to about 45 mph, the ECT rose back up to 188.
WTF? I've never seen/heard of ECT dropping while you're working the motor harder, although I'm also not that experienced with 6.0's or diesels in general. There's no puking, coolant level is just a bit below the MIN line in the degas bottle, but it is the gold coolant (until I change it soon).
Anyone have any experience/knowledge with this?
