Thank you all for the responses. Would anyone know if Final Charge is ok for the Cummins 8.3? I am in southern California and a local Cummins place said it would be 800-1000 for the conversion. Does it really have to be the Cummins product EAS Complete? And the portion on preventing an "air lock" how does that work exactly? Refill cooling system with tap water. IMPORTANT: Be sure to remove any air lock from the thermostat housing. Some systems have a hose set up for this—on ours I just loosen the coolant line to the air pump and bleed the air out. Should I just remove the thermostat and do the flushing with distilled and flush cleaner (which one recommended), or is there a better way?
And gatorcq, I am unable to open that link.
