2006 6.0 with 118,000 miles. did the coolant flush (restore/restore+/distilled water) replaced with ELC red coolant. do to large deltas from Scan gauge II read out, I recently replaced both coolers and IPR valve, did the freeze plug block on the EGR cooler. pulling the 5th wheel the EOT was hitting 235 at times. deltas where hitting 18??? using scangauge II to see these numbers. with out any exhaust entering the EGR cooler anymore, shouldn't the temps be down? Are the "normal" temps and deltas different with EGR blocked?
Gettng the P0401 code from the lack of EBP.
