So I've been through this before with some of you. I have made some changes since. Climbing a 6% grade for about 5 miles, 80 degrees plus or minus pulling around 10k. My engine temps climb to 230+ towards the top. I have installed and oil cooler. Man what a difference in oil temps. I went from 250 and at times 260 to my max during the weekend being 221. But, my ECT is still hitting 230+ rather quickly before I have to back way off. I'm running that Hayden fan clutch everyone recommend. I can hear it running, but it doesn't seem to have near the sound my stock one had. Any ideas what I should try next?
