    Hello everyone,

    This is my first post so my apologies if I mess something up.

    like the title says I have a 2008 vnl 670 with a D13 that overheats whenever I request a parked regen. It has overheated in the mountains before pulling 40k+ but other than that no overheating issues.

    I have reached the point that it’s in level 3 requesting manual regen but I can’t complete the regen due to it overheating and shutting off. I removed dpf filters and had cleaned manually but truck still wants a parked regen and still overheats. Changed thermostat and same issue.

    any ideas?

    Even with 40k you shouldn't be overheating on a climb. Maybe you need to clean out your radiator. I had to pull the A/C condenser, then separate the CAC and the radiator. After I blew everything out I had about a half an inch of crud on the floor. Didn't overheat anytime after that.

    I'm just curious is the fan coming on when the temperature gets hot enough to activate the fan

    Plugged radiator. Antifreeze, over the years, I think makes silica buildup inside the tubes. They used to "rod" the tubes, but that's when radiators had some meat to them.You can try a hose through the fins, I don't recommend a power wash, and then some air pressure, but sounds like a plugged radiator inside.
