6v92 mc9 adding coolant in freezing temps

[dtcerrato]

I left the diesel air heater running all night. It kept it around 45 inside. It runs inside the bay for the heater core. Keeps it warmer than ambient for sure. Just fire it up again this afternoon, sounded as good as ever.   

This bus gives me so much an it:-)

Lol, I guess the next best thing to feeling the heat when it's cold cold is the sound of the heating device!
