just my gut, i'm hollering BS on the cruise control.

a 25 degree delta between engine oil temp and
engine coolant tem is not "starting to go bad".
i had a 25 degree delta on mine, and the EGR
cooler had failed, leaking coolant into the intake
manifold, causing stretched head bolts, and blown
if you look at the coolant catch jug, and it has white
crusty stuff around the filler, or when you stick
your foot in it hard, you get a whistle, sort of like
a teakettle, you probably have leaking head gaskets
as well as the EGR cooler being bad.
by '05 ford was on it's third supplier of head bolts,
and while they are better, water in the intake
is the kiss of death for the head gaskets. it doesn't
for those of you folks running a ford 6.0 diesel,
vintage '03-> the single best thing you can do
to save yourself a HUGE amount of money is to
get a scanguage II at autozone for about $160,
and set it up to monitor some vital engine readings.
and change your engine oil every 5,000 miles....
this diesel isn't your mommy's diesel... it has
HEUI injectors that use engine oil to hydraulically
operate the fuel injectors, and the load on the oil
is horrific. the oil shears at a molecular level,
and breaks down.... not the additives to the oil,
the oil itself... this leads to damaged injectors
from scuffing.... amsoil will still test fine, and
the shear will let the injectors suffer. don't run
extended drain intervals on this motor.
also, RUNNING THIS ENGINE TYPE OUT OF FUEL
IN MANY CASES WILL DAMAGE THE INJECTORS
BEYOND REPAIR. air in the fuel system can break
off injector tips.
you ran your truck out of fuel? bummer. broken injector tips. $4,000 repair
you put the wrong coolant in the truck? bummer. oil cooler failure. $5,000 repair
you used a aftermarket oil filter? bummer. HPOP failure. $3,000 repair
you let the batteries get almost dead, and then tried to start it? bummer. FICM failure. $1,300 repair
you put a bully dog tuner on the motor, and broke the tranny? bummer. $4,500 repair
you used aftermarket fuel filters? bummer. water in fuel... and the list goes on.
and 'cause "the dealer" said it's broken, doesn't mean squat.
i went to a highly recommended dealer, with the thing smoking
enough white steam to kill every mosquito in four counties, and
the idjit service writer told me my 2006 was "regenerating" and
that was normal. nothing to worry about.
regeneration wasn't adopted on the 6.0 until 2007.
idjit. blithering idjit. and that was the most highly recommended
ford truck dealership in 100 miles of where i live.
