I just recently replaced my alternator and the belt. Somehow the belt cut a hole in my coolant hose. By the time I realized this all the coolant leaked out and the car overheated and stalled out. I bought a repair kit for the hose and fixed that. Started to drive the car home about 2 minutes later the car died as I was driving. I left the car sit for about 6 hrs and checked the dipstick. There was coolant on it. I spent the weekend tearing apart the car and the headgasket looks ok. I don't see how that the block or head could have cracked that quickly. Anyone have any ideas on how the coolant got in with the oil? There was also alot of oil in the filter housing?
