I have a 2000 3l and I've had over heating problems for about a year now. I've changed my coolant and flushed the system 3 times, replaced my radiator, replaced my water pump and put new seals in all in the past year. My truck is starting to over heat again and is leaking coolant. My coolant is a orange brown color and turns to almost a paste. My overflow container lid gets blown off and coolant goes everywhere. Does any one else have or has had this problem?
