I have a 1994 Freightliner FLD120 that has an N14 in it. Today it started blasting, and I mean blasting, antifreeze out of the radiator overflow tube. I didn’t know what to think, but I figured major engine problems. Just to be sure I unhooked the truck air brake compressor output line and the problem stopped. I then hooked it back up and as soon as the air gauge hits 60 psi, it started doing it again. Is there anything I am overlooking in assuming it is a failed compressor? I called and no one close has it. Looks like the soonest I can probably get it is Tuesday.
