That's my thing, these complaints don't add up...I've been down these roads, and the parts don't fail that easily...they're built to manage sustained temperatures in the 1400*F range...a little gas will junk them??


I'm not trying to argue, but it just doesn't add up why a little gas junked $10000 worth of metal parts...




See, that's a crap design on the engine manufacturer or builder. The EPA gives you a 45 minute window to no meet emissions on a cold start, in order to allow the tank and lines to thaw...if the engine shuts down before hand, that's all on the programmer. Ours will thaw a completely frozen tank in less than 20 minutes and go to work...If the on road guys aren't running a coolant loop into the DEF tank then they are retarded....DEF freezes at 11 degrees Fahrenheit!

I should have kept reading. This is exactly right, it's an implementation issue, not a system attribute.


I would demand proof that gasoline was injected, if it was, that's a system failure on the engine manufactures end. If the DOC didn't over temp, the claim is baseless. It's called a couple of things, but primarily an uncontrolled hydrocarbon thermal event. The gasoline should have never left the tank.
