2006 Cummins isx pushing coolant out the radiator cap

{"text":"Hi\nI just purchased a 2006 9900i with a isx in it. \nIt all of a sudden started pushing coolant out the rad cap. \nI put a new cap on and it stopped for about 4 hours and started again. \nIt only does it on and off not all the time. Last night I did a load and it pushed a little coolant out when I was loaded. I checked the sight glass after I was empty and the coolant was up in the top sight glass. I went and checked it when it was cold today and there is no fluid on the sight glasses at all. \nI had no warnings at all when I drove it. \nThe truck is deleted also. I have no smoke at all. \nI have check for combustion gas in the rad cap and had no reaction. \nAny help is greatly appreciated. \nThanks","pics":"[]","canComment":true}
