Coolant won't regen out like regular soot or even oil. After seeing all these filters I would be damn carful driving it with a load at all. I can't believe they run even in perfect condition. My filters had drank some coolant when it had a catastrophic failure before I owned it. Cummins replaced the first filter and left the next to regen its self clean. It didn't work, second filter was 50% blocked by some white putty looking crap. I'm pretty sure it was coolant that had been baked by 20000 miles worth of regens. Insight said it was fine but it did eventually throw a nox sensor code. Don't push it unless you just have to take the risk. Might be cheaper to dead head in the long run.
