How hot is too hot????

[Kappa Sig]

Been very hot down here in south GA recently, and pulled my 24ft enclosed trailer (guessing 10-12k loaded) during the middle of the day on about a 2 hour trip down I95. Outside temps about 100....heat index 110-115.....miserable out and about as hot as this truck will ever see LOL.

Normally....without the trailer and ambient temps around 80 or so I see ECT of 185-190 and EOT about 190-195. 5-7 degrees different about all the time unloaded. TRA temps 155-160 unloaded.

On this trip pulling in this extreme heat, ECT got as high as 215 and EOT up to 224. Biggest delta was 15 degrees, but was 10-12 most times. TRA temp got up to 175. Keep in mind extreme heat, but mostly flat, level ground in south GA, north FL. Speed was 72-75 most of the way.

Are any of these temps concerning at all??

2003 250 4x2 crew, 6.0. 158k, basically totally stock. Did the gauges first, exhaust coming soon.

Thanks

Your temps look good, with and without a load.

Besides the ECT/EOT delta....where should we begin to be concerned with individual temps? What is too high with these 3.....ECT, EOT and TRA.

Thanks

Yep your temps all look fine, no worries.

If you get worried at all just ease down a little on your speed and the temps will drop.

Drive north a few hours and they will go down!

Yeah......I get the whole slowing down and driving north thing....but that doesn't answer my question. Plus if you run 60-65 on I95 down here you will get run off the road.

When should I be concerned? ECT 230? 220? EOT 230? 240? I know slowing down will lower temps....what i need to know is WHEN to slow down

Thanks

Those are pretty conservative numbers, the factory gauges do not redline at those "alarms". The truck defuels about 240 ECT (starts at 221 according to what ive read) and 253 EOT, I'm making another UT trip next week, haul boat behind trailer, about 18k in trailers, from Vegas to UT, in 115 OAT, I run the whole trip between 215-235 ECT, 220-245 EOT, on the big hills when temps go passed 235/245 respectively we go AC off and windows down that usually stops it from going higher. I have all gauges, the stock eng temp does not move at those temps. Your going to be fine. I had to climb a NM pass last summer, there was nowhere to pull off, I got up in the 260s, even the stock gauge went up, I could feel the truck defueling, survived, changed oil and coolant.
