Towed the boat ran hot uphill

I towed the boat this weekend. It was 100 degrees ambient temp and I was going up hill. The temp was running 3/4 to max. Usually it sits at 1/3 to 1/2 on the temp gauge. and you could smell something burning. I shut the ac off, and it did cool down. Surprised as I never had this issue with my 2005 HEMI. Any issues for you guys! ImageUploadedByJeepGarage1471204109.272747.jpg

Re: Towed the boat ran hot uphill

My Ecodiesel ran at just over half yesterday with 100+ degrees including up a mountain where I live. The tranny temp is what I worry about more often. Diesels don't get as hot as gas engines do. Try adding a bottle of water wettter / motormax / purple ice as that will help drop temps a bit. You can also run a mix of 60% water and 40% antifreeze (instead of 50/50). It won't freeze unless it's really cold at that proportion.

Thanks for the advice I will try it.

Re: Towed the boat ran hot uphill

Perfectly normal.

I believe the coolant temp gauges on our JGC's are more "truthful" than most.
I've towed our TT with the JGC over 14000 miles and I've seen it "kiss" the orange and never go further. We've towed in 100+ temps without issue and, personally, I only watch the oil temps and try to keep the rpm's around 3400 on any grades. The engine management software will put you into limp mode IF you ever exceed temps/overwork your motor.

Re: Towed the boat ran hot uphill

I think I might have asked this in another post, but is that a real oil temp? Is there a sensor? On the cummins, it a calculated value, not actual- no sensor. Most of that dash stuff is just to entertain the driver. I don't trust any factor gauge.

I thought it was the oil PRESSURE that was a calculated value on the CTD???

Seems like the oil temp. would be based on actual sensor.

Are those products confirmed to be compatible with OAT coolant?

Re: Towed the boat ran hot uphill

Yes,
Regarding the EVIC inputs. There is an actual Oil Temperature Sensor in the VM 3.0 motor as well as the ZF 8HP70 tranny.

FYI - There is only an oil pressure "switch" not a sensor on our engines. According to the shop manual, if you need to measure oil pressure, you have to remove the switch and use a gauge!

Re: Towed the boat ran hot uphill

This is normal, everyone complains about the temps rising when towing uphill with the ecodiesel, but none actually overheat. I often see this when offroading up steep hills, the temps rise quickly, but it doesn't overheat, come back downhill and it cools quickly.

I believe it happens because the EGR valve closes when the motor is under load to provide more power, no recycled exhaust gas means higher combustion temps.

Re: Towed the boat ran hot uphill

The thermostat doesn't fully open until 225F, which is near the orange on your coolant temperature gauge. This engine runs much hotter than a gasser for efficiency. Normal.

The ECM will reduce fuel input (loss of full power) if coolant or oil gets too hot. You might slow down or drop gears, but it is not limp mode (limited to 3rd gear).

Re: Towed the boat ran hot uphill

Diesels run best when they run hot. All these comments about temps but almost no limp mode issues.
No need to worry...

Re: Towed the boat ran hot uphill

The thermostat in the EcoDiesel is 3 position thermostat(the mods can fact check that for me) and is never really in danger of overheating. Even when the needle is approaching the hot zone the thermostat is only ⅔ open. There is no need to worry. Just drive it.
