2 things:

make sure your fan clutch is working right. I believe you should be able to notice the drag on the engine, and the sound of it blowing more wind, when it's hot enough to fully lock up. I've no personal experience though.

second. You weren't towing in 5th/OD right? except maybe cruising on flat roads? It's bad for 5th gear longevity, and lower gears equal faster engine rpm which runs the cooling system faster. You probably know all this though.

 

Also, 210 ain't all that bad maybe. As long as your cooling system doesn't start venting or boiling over.

a shroud should help a bunch though.

 

I think its probly the Fan shroud. Ive had very little luck with properly working fans on my cummins

with enough coolant and heat dissapaiting from the radiator along with alittle air directed by the shroud it should run at thermostat temp pretty easy. Regardless of wether the Fan is going full bore or not.

your brush gaurd looks great and thsts a very nice rear bumper the one i have is just rust abd alittle paint

Been here all my life never seen a Wolf only tracks well do. Ive been wanting to run down a Wolf in the snow

There was about 30" of snow when we were up there. About 26 now . Thats at the gaurd Station. Theres 2-5 ft drifts up high.

Im ready to. We wanted to dive off the look put into the lakes but need 4ft more snow to do that

Just watched your driving vid. How much sir is that thing pushing. Pretty sure you tricked us and you have one of thisd whistling v8s under thst hood.

Looks drives sounds amazing. Thanks for shareing

 

Beautiful truck and really nice clean job on that Cummins installation!!! Massive torque and decent fuel economy to boot. I can only dream....

 

I have read that the 6bts run hotter, looks like you have the super cool rad, but a shroud might help but a pita to make. I have the 4bt and nv4500 in my f250 ‘72, I would say gear spread isn’t ideal but the Cummins handles it ok. I’m ultra picky with mine as this is my first engine rebuild, I have to remember to step back and say it’s running just fine, I worry about every little noise and such. I will have the radio on for a bit but then I get to where I’m saying I can’t hear the engine, need to shut the radio off to monitor everything.

Yours sounds like mine in the cab, engine noise significant. Not sure about your turbo whistle? I put the mat on the firewall inside, need to fit and install some insulation sheets to cut down on some of those decibels, glad I don’t live in an HOA.

Nice job, you should be proud of the result. I just sent my IP, injectors, and lift pump to Area Diesel Service in Illinois, everything runs a lot better. I had all new components but they had to wear in and then be readjusted, runs great now. Want to start tuning the air and pump.


Kinda jealous of you westerners with all your good driving territory out there! Nebraska is by and large a gravel road grid.

I've heard the opposite. But I'm sure it depends on your setup, environment, driving habits, load, etc...

 

Did you use a genuine cummins thermostat. I read a bunch of threads on guys having cooling issues because of (edit: not using) that.

 

Gates brand are good to go too.
