You can tell if the 6.0 oil cooler is bad on a 6.0 Powerstroke by monitoring for high engine oil temperatures compared to coolant (over a 15°F difference), oil or coolant contamination, restricted coolant flow, engine overheating, white smoke, or possible EGR cooler failure. Upgrading to a Sinister Diesel Heavy Duty Oil Cooler for the oil cooler 6.0 Powerstroke can help prevent these common ford 6.0 oil cooler issues and improve reliability.
