So I had to rescue my daughter stranded on the highway this morning. There was a massive coolant leak and she says the car was smoking before she stopped. I was able to get it off the highway to a nearby gas station where i could see, after the smoke cleared, that the drive belt was now off, not snapped but off and coolant pouring out of the bottom of the car. Got it towed home and from what I can see, it doesnt seem like the pump is where the leak is coming from. It appears somewhere below the pump. Could this be the UIM / LIM gaskets??? There is an oil leak but doesnt seem to be coolant in the oil or vise versa. And what would make the belt come loose? And to top it all off, now the key wont come out of the ignition. HEEELPP!!!

thanks!
