I hit 249 towing 17k up a 6% grade for 5min. If ford let's it get that hot. I'm not worrying about it. It's got warrenty. Run a good synthetic and rock on.

Did your coolant temp spike? Mine got to 227 which was about 5/8 on the stock gauge and the fan clutch did not kick in.

If you are really afraid of too low oil temps with a secondary air to oil cooler you can run a bypass thermostat. But going through the oil to water cooler first it won't need it.

220ish. It's always lower than the oil temp.

To me, unless your towing with a ton more increased power via a tuner. I wouldn't add more cooling with bypasses and such. Just more crap to go wrong.

I wonder what Corbin has been running for temps.

Running mobile 1 5w40 and will be towing in 100+ degree weather for memorial day. Towing about 15k up see 6%/7% grades will see how it does.

Yeah I'll be towing another big grade in the heat but I'm not even towing much weight. I'm just a little disappointed how quickly coolant temps jump. Warm oil temps on a working engine is something I would expect.

Does anyone know if any of the tuners can kick on the fan clutch a little sooner?

Is there coolant flowing in the oil cooler like the 6.0/6.4?

And 250 would not bother me as much if that was the high limit in 100 degree weather. I was not even pushing the truck in 50 degree weather and it was at 245 and climbing. Do anyone know if there is a high limit? will it start to pull power? I called my local dealer and they basically said if it blows up bring it in. That doesn't help me if I am stuck with the family on the highway.

Yes it has a water to oil cooler

Towed 15k with 3.55gears and 37s. Up a 6%grade oil temp hit 249 coolant 215. Fan kicked on and oil temp dropped to 230 FAST.

Interesting, my coolant temp hit 22x and the fan clutch did not kick on. I'm going to have mine tested.

Ipkyss · May 9, 2015

I guess its possible the fan turns on at 250 oil temp. Seems odd though

i run the mpd oil cooler because my block is filled, but i have yet to see over 200 , ever , and average cruising temp in 80* weather is 170 . not sure what it will look like in stop and go traffic at 100* + , don't really plan to find out. i do believe there would be very little rise in temp even heavily loaded , certainly not much over 200* .

Where's one of these lubrication engineers? Any idea where you wanna be? What's the window for best performance?

My oil and coolant temp stay around 200 driving around town unloaded. Curious what it will do in the summer here in 115 degree weather.

My coolant gauge doesn't really move. Need to check that if it does. Will be towing on memorial day weekend.

Bump, Ipkyss or anyone else change anything up?

Also, wondering if you could kick the fan on sooner via programming.

Jomax · Aug 22, 2015

So, I towed 15k up 7% grade here in AZ. Temp was 113degrees outside. Oil temp will not go above 252. Coolant temp hit 230 iirc.

I'm not worried about it. If towing heavy, I'd run a synthetic and enjoy the truck.

I got my oil temp up to 240* this week towing a good load behind the truck. Coolant and transmission stay well with in check though. I would like to get a cooler so the oil temps aren't holding the truck back so bad. Sucks having to back off so much going up hills because the engine oil is getting to hot

TrickTruck · Aug 22, 2015

My HD RoadGlide gets the oil up to 290°. I worried a lot, but the hipo shops in town tell me it's normal for them to get so hot and is nothing to worry about in terms of oil breakdown until over 350°.

I think that's really hot, but...these guys ought to know what they are talking about.

So maybe someone can chime in on where oil starts breaking down and at what temp you need to worry.

I tow 25klbs and haven't seen high temps on the F350 yet.

That camper you pull weights 25K and you pull it on the bumper?

Ipkyss · Aug 22, 2015

I have not done anything yet. The only thing that seems to help is if I manually shift and on the longer hills leave it in 5th gear longer then it normally would on its own. I found theres a lot of hills that it will pull full throttle in 5th gear where it would normally drop to 4th gear at the bottom of the hill and stay there all the way to the top. Even full throttle at 1800-2000rpms the oil temp won't go over 215-220. As soon as it goes to 4th gear and higher rpms the temp hits 248 really fast.

I am waiting for someone to come out with the right sandwich plate for the oil filter so I can add on a larger oil-air cooler.

TrickTruck · Aug 23, 2015

no, we gross 25k, no it's not on the bumper, it's on the receiver, they just call 'em a 'bumper pull'

redwhitenblue · Aug 24, 2015

Still would love to know if one of the tuners can kick on the fan clutch sooner.

Coolant definitely will get to 230 and oil temps 240's even with a light load if you're pulling a big hill. I backed down to the lowest tune and EGT's stay nice and cool but coolant and oil temps still get pretty hot.
