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.
