Overheat While Towing

This past weekend was the first time on a trip with the RV and Edge CTS. The drive was about 3hrs on flat ground in 80F weather. My guess weight on the camper is about 7~8,000lbs. Long story short, temps continue to climb at 65mph and hold steady at 60. I let it get to 225F on oil temp then backed off. Things cooled right down.

I've made this run several times at 65~70mph without the CTS, I just didn't know things were getting that hot. Dash gauges were all normal. If you are pulling a trailer you need gauges.

I have a recent EGR delete, new oil cooler deltas never went past 10F even when passing at WOT. Things do heat up very fast under a load.

Question is do I need to inspect/replace my radiator? Water pump? It seems like most people are not having trouble with my size trailer at 65mph.

Truck is stock besides mods in sig

I'd say you have nothing to worry about. If your temps were really within 10 degrees then that would put your coolant at about 215 which isn't bad. I believe the thermostat isn't fully open until 220 anyway.

TMAG,
What gears do you have? Where are your RPMs hangin at 65mph?

And i have gotten the stock guages to rise to 3/4 and overheat. 3/4 up the scale is about 258 EOT and 245 ECT
