(New egr) n then like 3 months we took def out.. next was air compressor, that was inspected no signs of colant anywhere... so now we taking the head off, ones thats off we will be able to c more.. so thats my update..

You don't take the head off until you pressurize the coolant with the oil pan off. Otherwise there is a possibility that you may never find it. Skipping steps often leads to mistakes that cost you big time. That is why Waterloo's truck is being re-manned a second time. No one bothered to see what was wrong the first time.
