Ford E-450 6.0 Turbo Diesel Overheating

Are you going off the in dash gauge or are you running a scan gauge or something? If you do not have a means of seeing the actual temps then it may be a bad gauge. Get a scan gauge 2 or some other system to monitor the temps and other needed items. Only thing it wont monitor is boost and EGT's. Maybe not fuel pressure. The 6.0 needs to be maintained better than the average vehicle. Mine has had new egr (BPD) and new oil cooler installed. While it was down had the guy install new head studs. He is a ford tech and he took it up to all the latest TSB's before I got it back and we have not had any issues, but this is a F series not an E. ALso he did the Blue spring fuel pressure mod and a couple of others. I changed to Cat ELC colant from the ford junk, also check your rad cap to ensure it is hol;ding pressure. I went thru 4 before finding a good one. Most auto places have a checker to utilize but most employees dont know how to operate it!
