08 F250 Puking Coolant
Ok seems this is a common issue, but potentially someone can point me in the right direction.
08 F250 6.4 160K miles.
original radiator blew at about 140k miles. New installed and no issues
Water pump has been changed as well as tstat
Pukes coolant out of degas bottle (new cap installed to no avail)
venturi T issue installed
Spartan 75 150 and 250 I think (keep in 250 tune for mileage improvements)
EGR block plate
No white smoke or liquid coming from exhaust
Coolant temp when fluid is in and to near recommended level 194 avg when engine oil temp is 230 avg after running a while say less than 3 or so hours.
Highest Temp I have seen is 218 coolant temp 260 engine temp but only in short bursts and long time (4+) hours of driving. At this point the average is 205 ect and 240 eot.
SO... that being said, what do you guys think my issue is. Ive been told EGR and also Head Gaskets but woulnt I see white smoke or something. Im no mechanic although I did change the water pump and tstats when I first realized that it could be an issue. Any ideas will be appreciated. Thanks
