Why does it have to be replaced just because of the wrong fluid into the exhaust? It can't "damage" the filters in there, as well as the DEF system should have known the DEF quality was incorrect as soon as it sucked some up.

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...

So at least 3 of our trucks will not run on their own for longer than 5 minutes without a driver restarting them every 5 minutes until the DEF is thawed and can circulate. We only have 8 road tractors here and 6 of them are emissions trucks now) Usually I have to go down there and use a heater, warm the tanks up, and hopefully when they get to a long stop, they don't let them set for ever and freeze. I'm all for not retiring our old FLD's now! They should have just started restoring them. Haha
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!
