EOT and ECT temp questions

ok so Im pretty new to the 6.0. This weekend we took the excursion up to winterpark from colorado springs. The way up we had a nice 50-60mph head wind so the drive sucked... My question is driving my EOT/ECT temps run anywhere between 8-11 degrees different, but on the long uphills really working the truck i was getting 15-17 degree difference but soon as we got onto level ground the temps went back to the 8-11 degree difference.. now the trip home on the same hills without the nice head wind the temps were anywhere between 8-12 degrees. My question is when your really loading the engine the temps go up and hit the 15+ degree difference mark, does this mean my cooler is going bad? we have a full gauges plus the bullydog monitor thing, but we dont run the tune, we just leave it stock..

Temp deltas will change with the terrain. The only way to truely know is to drive it on level road, at 65mph, for 30 minutes. If you see those high temp deltas (10-15 degrees) during that test, then there is a good chance your cooler is clogged. So go find a flat strech of road and test it out. Good Luck!

well thats good news, the last part of the drive into colorado springs is pretty flat and we ran between 65-70 mph for a good 45 min and the temps stayed between 8-11 degrees.. i was just a little nervous when the temps in the hills started getting 15+ degrees.. It was also anywhere between 14 and -2 depending on where we were in the mountains so maybe that had something to do with the big temp difference..
