Anyone use Arctic Fox fuel tank heater with TK Evolution?

What are those covers? Do they just stop ice build up on the radiator?

 

Keep heat in the radiator.

 

Thanks, how cold does it need to get to put something like that on?

 

I have a carrier apu I just leave it on battery monitor mode and set my timer to start and warm up the truck 2 hours before I intend to leave. I can usually get non biodiesel and rarely treat fuel. Unless -15 below or colder I usually fill up with treated fuel so no need for me to treat fuel. Truck starts just fine up to -25 in this situation.
Load test on batteries and do voltage drop test and clean all terminal 2 times a year . I run 3 DD15 engines and have yet to have a problem with any of the trucks starting even after a week of cold soak

 

Engine manual for DD15 engines only recommend the winter fronts for 0 deg or colder. Removed for anything warmer. The new engines run hotter than the older ones.

 

Depends for me. If it's in the teens during the day, I'll throw it on. In the fall I take it off and put it back on a lot because of the wild temp swings here in the northern plains.

 

When you can't keep your engine warm enough. Its about negative 10 here now and I'm still running about 190 without one
