A buddy of mine just got his first diesel, a 2003 6.0. He's had a bad string of luck already, even though he's doing everything right. Long story short, it overheated when he was a long way from home, and it had to be dropped off at the local Ford dealer. He had just done a new oil cooler and an EGR delete. He was running Eric's x-street tune, basically stock otherwise, on 37" tires and stock gearing. The truck kept pegging coolant temp. They diagnosed it as bad headgaskets... I think he got two new heads, gaskets, studs etc...
Fast forward to now, truck seems to be running great, but he's noticing coolant temp is steady at around 190-200, and oil temp goes up to 240.... what the heck is going on here? Has a new oil cooler too... thoughts? This is just cruising down the highway.
