Hey guys,
Diagnosing a Duramax recently and someone asked me wh going through coolant and a hard upper radiator hose in the morning indicates a failed head gasket or at least leans heavily towards that issue. My question is, I could explain help the truck uses coolant but I couldn't thoroughly explain the hard upper radiator hose as to why it they are suppose to check in the morning and see if the coolant system stays pressurized or builds more pressure over night
I always thought it was cause the specific cylinder the head gasket failed on which is #8 on this truck would be on the compression stroke when shut down and bleedomg the compression off over night.
Egr is deleted on this lml as well. So couldn't any body explain that a little more in depth please! Thanks!
