    2013 International prostar with Maxxforce 13 engine. For past 2 months since I have changed my cracked radiator fluid reservoir. I have been losing coolant, it’s 1 gallon every week and I can’t find any leaks.No coolant smell from engine oil. Btw I have been running with egr sensor unplugged for about a year now. Can anyone help.

    EGR coolers can leak and they are worked hard in Maxxforce engines.

    Very common problem. 100% failure rate. It has been talked to death on this site over and over again. If you perform a search you will find lots of information about it.
