Air Compressor air in coolant.

[Waterloo]

All right, I'm going to ask, how does the air from the compressor work its way into the coolant system? And what fails on these ISX compressors, is it the rings or a valve? The compressor head gasket? I'm probably not the only one curious about this. My compressor is failing, have to run a short load tomorrow and then heading in to the house to replace.

Well, quickServe is your friend! Coolant lines into the compressor! Imagine that? LOL!

But still, where is the air escaping from in the compressor to make it's way into the coolant system? Is it bad rings, compressor head gasket?
