Well I guess i'll start by saying I was at the drag strip and at the end of my run coolant temp peaked at 210...no big deal then on the return road it suddenly dropped to 180 I thought it was just lag in the sensor or something. Well long story short I go pick up my slip and the guy tells me my truck is leaking something so I start looking around and it's coolant. I can't really tell where its coming from right now as it was dark out but I noticed that both upper and lower coolant lines are completley sucked in/ collapsed on them selves. I don't know what would cause this. But if any9one has any ideas on it I sure do appreciate it. James
