Yes heaters fail, never had a tank crack tho
Funny thing is I've had 4 or 5 tank heater trucks, stuck in salmon arm with speed restrictions, this summer
Even tho it doesn't need the heater right now, it needs to see its working or it will limp mode itself
I'm not too up to date on the automotive SCR systems but I'm guessing these heaters are electric? I know with Volvo construction equipment (I'm a dealer tech for them) that they're all coolant heated with the lines outside of the tank electrically traced. Knock on wood we haven't had any major issues with any of the tier 4 final equipped iron.
