I have 98k on my truck and I am on my 5 coolant filter change. This is what poured out of the filter. I figured at this point of being on my fifth filter change that most of the trash would have been cleaned up by now, but have was mistaken. One of these days I wil open one of these filters up and see just how bad it really is. But this picture is for those that dont have a coolant filter on their truck yet. This was money well spent.
