I tow my boat on the weekends about 100 miles each way, 95% highway. Heres the stats:

55-65mph average
3 guys in truck, maybe 200lbs gear in bed
Boat/motors/trailer/fuel right around 10,000lbs
SCT custom tow tune
Always keep EGT under 1000*
Air temps have been between 75-100* (Ill bet the air is hotter than 100* on the ride home on the highway with all the cars on the road)
All numbers coming from my Edge


I have been seeing 198-210* ECT while towing & 200-215* EOT. Never more than 12* apart, sometimes as close as 4*. But I would say averaging 8-12*.

I replaced my oil cooler last year. I just had new HG's installed, coolant flushed, and Shell EC1 coolant with distilled water added back in April.

I run Shell T5 or T6 every oil change, never more than 4000 miles.

When not towing ECT and EOT are usually about 5* part, and rarely get over 200*.

Is this normal in this summer heat? Or should I think about the BPD cooler or replacing my stock oil cooler?

thats normal any higher than 15* for EOT-oil cooler.

I would say thats perfectly normal. Thats about where mine runs and I just had my coolers replaced. Disclaimer: I ain't an expert on a diesel engine nor have I played one on T.V.

Looks like my temps too ... I have a one year old oil cooler.

Great, thanks guys. Last year I had a much smaller boat, only about 6000lbs, and my temps werent this high.

I kinda figured it was normal, but wanted a second opinion.
