I was told today that my cooler hose ruptured and I had to take it immediately to a auto repair shop. I was driving to work and the car started making a clicking noise and felt weird to drive. I got to work and was told to check the dip stick. Was told it sounded like I had no oil. I was thinking, that wouldn't be right I just got an oil change about a week earlier. It was bare. Completely empty. I then proceeded to get it to a repair shop as it was an emergency. The auto place told me that it needed a kit that they would have to buy to replace the cooler hose and would take awhile to fix this. It would be the only way to fix this. And they cant guarantee me the engine didnt get effected by this situation. I did my research on this issue and it is extremely dangerous and expensive. I am now out $500 and half a day at work. I was driving to work at 7:15am on highway 44 going about 45-55 miles an hour. It was terrifying and once I got to my work and realized that my van could have stopped on me in the middle of traffic whenever it wanted to this morning or the engine could have blown up and cause a real accident. This is a serious danger to me and people around me. I had no clue I was in danger, I had no idea that my van was messed up. There were no signs, no problems, no anything. It just out of nowhere drained the oil. I drive 35-45 miles to work. I wish I would have known about a "recall" on this. I wouldn't have had it checked way before.
