I heard my fan kicking in when towing to rre last year. That truck was hating life. It was kicking in at 70 MPH.

Pry how my trans fluid got burned.

 

Iv melted down a 7.3 because it's got too hot...

And iv seen 246* in my 6.0 Excursion. That was flat ground in cool weather to boot!

But yea anything under 240 is fine unless your running it that hot a LOT

 

Yeah JP, but you are probably taking coolant temps. I am talking strictly oil temps. I have seen 240* when the coolant was only at 205*, but not for very long.

 

Nope, oil temp according to my OBDII and an app. My coolant was always steady at 186*. Needless to say it needed an oil cooler BAD.

Who in the world is tainting our conversation with six liter talk lol

 

So you melted a 7.3 due to hot oil temps ALONE, no other factors? Coolant and flow was fine, but EOTs got out of control?

 

Water pump went out and dumped the coolant. So I suppose you could say the oil was hot lol. But no, its wasn't hot oil alone

 

It worked out for me lol

 

Right, so I stand by my statement LOL

 

Speaking of working out.drove the big red dog to the other end of Indiana and back over the weekend. I delivered a doolie bed to another member for his project.it was adorable pulling the itty bitty utility trailer on the way back with the big red dog.
No issues to speak of with the truck and got 20mpg hand calculated.thats a win in my book!

 

That bed looked so cute on that trailer...




You should note that bed was unloaded with in 20 min of arrival....plus another 30 min of b.s.ing.....

 

Lol true story! Wish I could have ing around longer. Those dang weekend trips are always too rushed.

 

Have you had a chance to swap out your T-stat yet and see if that helps the EOTs? I was thinking of you yesterday while dragging my big 'ol heavy box around. I had several goot WOT runs that got my EGTs up in the 1100 degree range and EOT was rock steady at 212-215 degrees. Made the 'ol work truck snort though!

 

The 180° stat helped immensely this summer . the old rag did much better pulling with oil and coolant when pushing hard. It may be cool for winter driving but we shall see. More improvements in the works...stay tuned...

 

Diy doolie coming soon thanks to the hillbillie lol

 

How'd you do that tailgate? I need that.
