so my 08 6.4 has dpf removed and the egr and dpf deleted I have 150k for milage. So my issue is I think I'm starting to leak coolant and when I accelerate my truck squeals.
Is your coolant level dropping or do you see wet (coolant) spots on the engine? I would think that if the belts are wet enough to squeal, you would see something...otherwise I would be looking at belt tension.
FWIW... If the system is loosing coolant, the source of a leak might not be readily apparent. My brother's 6.0 developed a pinhole leak from a crack in his radiator last year....we had to pressure test the system to find it.
