Wrench light
What is the delta temp that sets the wrench light? After doing a non chemical flush when I replaced my A/C system, I clogged my oil cooler. I went from 8-10° deltas to 18-25° deltas... I set the light twice today.
Fortunately I have all the parts to do the job but I think I'm going to do a chemical flush this time to make sure the system is clean. May also move away from the Gold coolant.

I changed the oil yesterday before my trip, so I am hoping to baby it another 5k before tearing it down.

ECT 190-194 EOT 212-218 of course the Dashboss doesn't tell me what set the wrench light. It's not going into limp mode so I am just making an assumption that is what's causing it.

I believe you are correct.
I was under the impression though that Shane was getting the wrench light for the oil cooler efficiency code (PO12F IIRC) and not straight oil temp.

I think you got your two numbers mixed up. Also my Dash boss tells me what set the CEL. I was always under the impression that anything over 15 degree spread while warmed up and cruising at 65 meant it was time to change the cooler.

Umm ,if may say something constructive for a change.I'd change it ASAP,reason being is my truck sitting in the the driveway dead as a door nail BECAUSE I put off doing a simple fix that turned into a nightmare.............FIX IT NOW.......and that's all I have to say about that.

My DB will show codes that set the CEL, but no dice on the wrench. The problem with the test is.... WHO drives 65???

I was gonna do the oil cooler next month when getting the studs installed, but now it looks like I will have to do it sooner.

As stated above, I was told that the VXCF9 strategy in my PCM will set the wrench light when the ECT/EOT delta is too high for a certain length of time and engine load.
Like suggested, I'm gonna have to park it (except for some short runs) until it's replaced.

Latest flash
I think this is all I have seen on how the flash thinks. No numbers but it does include the oil cooler effenciency monitor:
FORD: 2003-2005 Excursion
2003-2007 F-Super Duty
2004-2010 E-Series
This article supersedes TSB 9-7-11 to update the model years covered and Integrated Diagnostic System (IDS) calibration level.
ISSUE:
Some 2003-2007 F-Super Duty vehicles, 2003-2005 Excursions and 2004-2010 E-Series vehicles, equipped with a 6.0L diesel engine may exhibit hard start, no start, white smoke, lack of power, running rough condition after cold engine start up, or diagnostic trouble codes (DTCs) P0404, P0470, P0611, P1260 and/or P1378 issues. Refer to the Calibration Content for information detailing specific vehicle content by vehicle application and model year that is being addressed by this calibration update.
This article includes previously released calibration content that improves injector performance in cold engine operation and additional diagnostic capabilities and product protection strategy enhancements. These enhancements provide additional diagnostic capabilities, adds additional new DTCs and engine protection strategies. Refer to the Calibration Content for additional details. See the appropriate Powertrain Control/Emissions Diagnostic (PC/ED) manual for technical descriptions and diagnostic routines associated with new DTCs.
ACTION:
Reprogram the powertrain control module (PCM) using IDS release 63.13 and higher or 64.01 and higher. The transmission control module (TCM) and fuel injector control module (FICM) , will automatically update if they are not at the latest calibration level. This new calibration is not included in the VCM 2009.11 DVD. Calibration files may also be obtained at Buy Motorcraft Parts Online | Official Motorcraft Auto Parts Site | FordParts.com.
CALIBRATION CONTENT
Reprogram the PCM to the latest calibration following Workshop Manual (WSM), Section 418-01.
The PCM and FICM calibration update contains improvement actions to address the following symptoms:
2005 F-Super Duty 6.0L:
False DTC P0470 - Exhaust pressure sensor A circuit fault due to a freezing condition.
False DTC P0404 - Exhaust gas recirculation (EGR) performance due to a stuck turbocharger condition.
Cooling loss protection - Revised engine protection strategy when an engine over-temperature condition is present. Vehicles updated with this service calibration will display higher temperature gauge readings when high engine oil temperature (EOT) conditions or high engine coolant temperature (ECT) are encountered and may disable EGR operation to prevent possible EGR cooler damage.
Oil cooler efficiency monitor - DTC P012F stored and wrench warning lamp illuminated when the oil coolers efficiency drops below a specified threshold for a given speed and vehicle load condition.
Turbocharger vane sweep strategy - Performs a sweep of the turbocharger vanes and unison ring during stationary idle conditions. Vane sweep can occur once per hour to help reduce turbocharger sticking.
FICM low voltage detection monitor - DTC P0560 stored and wrench warning lamp illuminated when PCM vehicle power (VPWR) parameter identifier (PIDS) is below 10.25V for 60 seconds or below 9V for 4 seconds.
Turbocharger over boost detection - DTC P0234 stored and wrench warning lamp illuminated when a turbocharger over boost condition occurs.
