40 degree delta
My Edge Insight CTS arrived in the mail yesterday. I ran my new to me, 2004 6.0 for about ten miles today. I was running 65mph with the AC on max the whole way. The coolant temp was 188 and the oil temp was 228. That's a 40F delta.
From what I read on this site, I need an oil cooler. Do I need to check my head gaskets? What should I be careful of until I replace the oil cooler? Should I drive with my foot off the gas for the week or so that it will take to get this thing fixed?
I'm performing the flush and fill procedure this weekend including backflushing.
