Checking for nitrous in coolant
A friend of mine has an '04 6.0. His oil cooler plugged, causing damage to the EGR cooler and EGR valve. He had it all replaced, and his mech. told him he needed to check for nitrous in the coolant. My (and his) question, how do you check for nitrous in the coolant. what level of nitrous is not acceptable etc. etc. Is there any validity to this? I damn sure don't know everything about diesel engines, but I have never heard of checking your coolant for nitrous, and I have owned 3 diesel trucks since 1996, and do regular maint.
Just wondering if anyone knows about this.
