The air for the engine compartment needs a way to escape and hood louvers will not let air escape at freeway speeds, have you ever considered fender vents, may not do any good if you have no fender liners.....

i just need to stay on cummins forum more
its the original from 01.5. Very well could be but when i had it out for the motor build, she looked very clean inside looking in both ends of the hose connections. it had Dexcool all of its life, changed every 50k until the motor was built and i swapped to reg green stuff.
It's probably clean then... Just a thought. I'm sure you have cleaned (power washed) between the rad, condensor, and intercooler?
yes, did all that the beginning of 2014 when i did the new intercooler. have a total 15k miles on it since then and temps show to have dropped a tad from last year with the fuel cooler so its not packing up with anything. it actually had very little crap in the fins when i washed it back then and it had never been touched in 185k miles. Nothing like the rads/condensers i cleaned in the cop cars lol
i was reading some testimonials from that coolertowing.com and noticed their oil temps are waaaaay up there compared to what i see. there are guys hitting 300*+ of oil temp and coolant staying between 203-215* with the extra radiator they sell. the fact im 40* below them tells me that oil cooler out front is doing a damn good job and disproves my theory a bit

yeah your telling me! 260 i draw the line. i can hit 240 fast and hold there for quite some time, then its a slow creep as coolant comes up with it. hammer up the hills when i hit 240 coolant, i was surprised to see oil never go over 260.
im really curious how well the internals in the motor are looking after 35k of this abuse. im really happy with how well shes treated me
I strongly believe that oil temps are a great indication of piston temps, and I believe piston temps are very closely related to piston failures. I've lost too many pistons to find out exactly how hot it can go before there is a problem, and to me, 240 seems like a good spot to start easing back on it. For the life of me, I can't figure out why anyone would knowingly let it get up to 300! It boggles the mind.

300+!!!??? Holy hell. No way would I keep running at those temps, those guys are nuts...
The fact they cant see it is a good reason. i would bet you 80-90% of the dmax trucks pulling loads up our hills out here hitting 230-240* coolant temp have oil temps hitting 300+ degrees. when i didnt have a cooler, i hit 270-280 with ease half way up the hills. it was an eye opener
I don't doubt they're getting hot, but I would be surprised if totally stock trucks are getting that hot. I don't tow many large loads, but a couple of summers ago I hauled a few big loads of wood pallets (grossing close to 30k lbs with a huge wind drag). I was seeing in the neighborhood of 1200 degree exhaust temps, 200 degree coolant temps, and 240-250 degree oil temps. This was all running 4th gear for the most part at 55 mph in relatively flat northeast Texas. I could have gone faster, but there's no way a stock truck could have gone much faster if any. It was working the truck pretty hard.
I just pulled our backhoe (14.5klbs) on our tandem dual gooseneck trailer that weighs in the neighborhood of 8k the other day when it was around 98* out. Runing 65-70 temps were around 210-215 going up the caprocks which can be 5 miles stretch I saw 225 ECT. once. Trans got to 217* and oil temps I saw spike at 245*. I pushed it hard too. I'm at 4600 elevation also. Now my stock lb7 runs around 10* cooler on all parameters then my twined LLY pulling the same load during the same temp. In fact I've never seen coolant temps above 215* ever in my lb7.
Brian posted he hit 272°ish with his lbz tow truck hauling his race truck.. With just a tow tune
i have a right side inner fender i can put back in if i do some modding for the second turbo. worth a shot
you guys have to rememer, there is a HUGE difference between 100-110 degrees outside temp, plus the fact it was 65% humidity that day too. the radiant heat coming off the road/ground increase intake temps to pretty unbearable temps. if we only saw 100* days out there, i wouldnt be worried about temps cause everything stays pretty close to in check even when hammering on it. 170* intake temp is pretty ridiculous and that wasnt even the peak i saw. at 95* coming home, pulling the big hills coolant got to 220, oil to 250, fuel to 180 and thats me flat footing it twice, 3/4 of the way up the hill going from 3rd to 4th gear up to 65mph from 45mph. the same instances at 110* would put me at the 240 mark on coolant, 260*+ on oil, and 200*+ fuel temps.
im not saying its only here for those temps or that you guys have never pulled in that, i just see what outside temps your giving me and comparing them to the differences i see. you would think there wouldnt be much difference but its a high of 102 today and im actually excited for it so i can go work on chet in the garage and the swamp cooler will actually make temps nice inside. 110+ it just flat hot
Tow tunes aren't stock. Most tow tunes have a significant amount more timing than stock which holds more heat in the cylinders putting more heat into the pistons which heats up the oil more. I may have to throw a totally stock tune in my truck and see what the temps look like.
We have days that get that up to 110 here too. Not as often as you, but it does happen. Some summers are worse than others, and we have been blessed with a mild summer last year and so far this year too. However, it's not at all uncommon to have highs at 105+ at the peak of summer with humidity over 80%.
Really the outside temp stuff is pretty irrelevant to what my point was. What I was getting at is my LBZ with no auxiliary oil cooler did a pretty good job of keeping my truck cool with a substantial amount more load behind it. Granted, I was only running 55 mph, but if I had an external oil cooler, I think I had enough radiator to keep the coolant temps in line and allow me to run faster without heat being much of a problem.
Your intake temps are not helped by the fact that you have an open element filter with no box to keep from pulling in the hot underhood air right after it comes out of the radiator.

I've shielded the intake from below and to the side. While it's not as tight as most ones you buy, it's blocks 90% of what the fan may be blowing at it. It's basically sucking air straight behind the headlight and out of the fender.
I see what your saying though on the load

My gauge warning light is set to go off at 225 on the lbz. Have never seen over 240 with the oil cooler install. On my LLY with no cooler its seems to run at 220 on level ground and have seen 250 pretty quick on a few hill. I am a bit of a ***** when it comes to fluid temps. I back out of it pretty quick.
Man, you guys wouldn't want to see what the 3.0 EcoDiesel runs for oil temps when loaded then...
I've seen over 280 just towing a 6000lb landscape trailer around the hills here. It sure is disconcerting to see but it is perfectly normal for that motor....somehow.

I didn't say they weren't open, I said they aren't full open until 212. 212 is the temp where the front 185 stat blocks the bypass off fully.
EDIT: just pulled up the specs and stock stats are not full open until 230 according to the OEM manual. 212 is where the bypass gets blocked, but 230 is where both are supposed to be full open according to the general.
