08 F450 6.4L Wrench Light on?
Hello I bought a 08 F450 Stake Bed from a local company that claimed coolant in the oil and it was deemed too old to fix. It was one owner with 88K miles. I took it to mechanic/friend 180 miles away ...

The wrench is usually a reminder for service or in worst case an issue with the throttle pedal.
Unfortunately that's not the case with these trucks. It is usually a sign of a big problem, like a big spread in oil/coolant temperatures which indicates a failing oil cooler, etc. These trucks can run into huge money for repair bills in short order.
I was lucky that the computer in my 2003 6.0L wasn't nearly as advanced as the newer trucks and didn't cause any CEL's because my oil cooler was failing. I routinely had coolant/oil temperature spreads of way over 15 degrees F and it was happening driving solo near the time I traded the truck off. I understand the newer trucks will have a CEL under this condition.
