I was driving around town this morning when suddenly the steering became really heavy and the dashboard displayed the Battery and Oil. I pulled over to the roadside and found that neither of the belts were rotating, thus not turning the alternator, water pump etc. The cause appears to be a loose crankshaft pulley bolt which released the tension to the belts. So now I have two questions.
1. Why would the bolt become loose on it's own? I've been driving the vehicle for a few months now, without incident.
2. Is it likely to have caused any damage to the engine?
