6.0L Power Stroke Oil Cooler Symptoms and Diagnosis
If your 6.0L Power Stroke runs oil hotter than coolant at steady highway speed, the EOT vs ECT delta is the first test to run. EOT is engine oil temperature. ECT is engine coolant temperature. On a warm truck at steady cruise with no trailer, a consistent gap of about 15°F or more, with the oil hotter, points to a restricted engine oil cooler.
This guide covers the 6.0L Power Stroke in 2003 to 2007 Super Duty pickups. It explains why the delta matters on this engine, how to run the test, how to read the result, and what to check before you order parts.
P0299 Code on a Diesel Truck: Causes, Fixes, and What to Check First
If your Power Stroke, Cummins, or Duramax just set a P0299 code and the truck feels flat when you hit the throttle, you are not alone. P0299 is one of the most common boost codes on diesel pickups, and it often shows up while towing, climbing a grade, or pulling away from a stop with a loaded trailer.
The code is a starting point, not a verdict. Most of the time something around the turbo is leaking, restricted, stuck, or reading wrong. This guide covers the platform-specific causes, how to test in the right order, and what repairs cost.
