NW Pa. | I have a international 9200 with a c12 in it. Went to start it today and the relief valve starting blowing air on the compressor. I assume the air system must be froze(Got down in the low 20's for the first time.) It does it right when I start the truck so I a assume air cant go to the supply tanks. I put alcohol in the glad hands and the pressure line from the pump. Still doing it. Do you think a torpedo heater on the evaporator would be a good place to start? | |
