I have a 2004 F250 (late build 6.0) with about 180K miles on it. Mostly stock with a magnaflow exhaust, and leveled.
Within the past 6 months I have replaced the EGR cooler, oil cooler, EGR valve, #2 injector, FICM, alternator, both batteries, front end tie rods, and ball joints and other normal maint. stuff. Truck runs great..
Last month, we pulled our toy hauler (about 7K#) up the Eisenhower pass... ECT temps hit 228 and oil temps hit 235... (using Dashboss to monitor).. ran great with no issues at all...
on the downside of the pass, the temps dropped and the oil actually dropped cooler and the coolant temps. After the two hour ride back down the pass, through town and to the house, I had EOT at 192 and the ECT at 199 at idle in the driveway. Ever since then, the EOT is always about 5-10 cooler than the ECT.
After sitting over night, both temps are within 2-4 degrees of each-other so I am assuming the temp sensors are ok.
This has been the "normal" for the past few weeks... truck runs great, no CEL, no codes and nothing else other then the EOTs being a bit cooler than the ECT all the time... I am typically seeing 190 EOT and 195 ECT for normal city routine driving....any ideas what is going on?
