You may see the broken belt pieces. Pray that's not the problem because if it it the engine may be destroyed. DO NOT TRY TO CRANK THE ENGINE until you see what happened because on the slim chance the motor may be repairable you may eliminate that possibility ( If that belt breaks on some engines the valves collide with the pistons)
