i know it has been 100f in my area recently so it is to be somewhat expected, however, i am fighting a cooling problem.
175k~ supposedly headgasket was replaced at 150k
td04 15t 30-40PSI
good aluminum 3 core radiator, clutch fan running and electric that kicks on at 190
Current tests, 160 tstat runs hotter, 180t runs hot but better, no stat runs cooler overall and cools down better
this is mostly flat ground, slight slope, gearing at 50mph is 1400rpm or so and 0-3psi. 70mph is 7-10psi at 2400rpm
runs cooler at 50mph, in OD at 1400, with OD off at 2200rpm it gets warmer..
I have a new water pump, have not installed it, with stat out you can see coolant flowing fast.
Im thinking maybe cracked head?
Oh, EGT at 50 is 0-400 depending on load
EGT at 70 400-800 depending on load
EGT is AFTER turbo about 2"
Meth injection running washer fluid, does not help at all no matter the settings
