I hope you got her straightened-out. I recently had 3 overheating events on a trip with ECT rocketing to between 240 and 253f. A new BPD water pump (amongst other things) is going in this weekend. Here is a link to my thread on Powerstroke.org: http://www.powerstroke.org/forum/general-6-0l-discussion/477257-unusual-problem-rapidly-increasing-ect-puking-normal-eot-pulling-grade.html
Another thing you may want to consider is adding a manual fan control switch. I did this on the side of the road after my 3rd boil over in 2 days, and man does it bring the ECT down in a hurry. I would switch the fan on at the base of a grade and it would lock-in at 100% with 5 seconds. At the top of the grade I would then switch it back to "automode" letting the PCM take control of it. Worked like a charm! Nothing like climbing a grade and seeing the ECT and EOT dropping! Here's a how to thread: http://www.powerstroke.org/forum/general-6-0l-discussion/225699-manual-fan-control.html
Caught your thread over there. I still cannot figure out the mod, so many different versions in that same thread. Where did that guy go who was going to build a box for that?
Not sure where he went.
It doesnt need to be very complicated. Once I change my water pump this weekend I plan to make a more permanent fan switch (versus the one done on the side of the road last week). I plan to use Upfitter switch #1 to trigger a relay, and the realy will switch a ground connection to the blue wire going to the fan clutch.
Currently I used a "tee-tap" connector to tie a wire to the blue wire leading to the fan clutch plug. I then ran the wire through the firewall and popped it out near the ash tray. I then hooked the wire to a simple rocker switch. After than I ran a short wire to a body ground and connected it to the other side of the rocker switch. So, when the switch is off (open connection) the fan is controlled by the PCM. When the switch is pressed the contacts close and and a ground signal is then sent to the fan clutch. Within 3 to 5 seconds the fan lock's-in at 100%. Simple and easy!
I do have on upfitter open but saw all the warnings about using it, so I may hit you up on PM and have you splain it like a 4th grader for me. :)
No problem Rolling Rock. I built a relay setup yesterday to allow me to use my Upfitter Switch #1 as a manual fan control switch. When switched on, the upfitter swtich will provide 12v power to the normally open relay, causing the secondary contacts to close. When the contacts close this will allow the jumper wire attached to the fan harness to ground, engaging the fan 100%. I plan to install tomorrow and will post pictures afterward.
