I have run it about 15K miles since it started last winter. Coolant consumption is erratic, but averages about 1 gallon per 500 towing miles.
The truck was sold last week on Ebay 'as-is' with full disclosure of the head gasket problem. The buyer can do the work himself and was happy to find an inexpensive 2001 with extras.

Good Day!
Would pressurizing the cooling system with a Stant or similar, with engine off & cold, have helped find this problem, particularly since it seems to be tied to cold ambient temps? I know with my ancient stuff, it has ALWAYS gotten me to the problem, although I've not had an internal leak yet. My understanding is that if a head gasket or such failed, pulling the glow plugs, pressurizing, & waiting would eventually make it clear what was leaking.
Just a tech-type question from one who'd like to know more... I don't even know if a DMax has glow plugs, for that matter.
Thanks & Blessings!
