Which pulley's does the motor actually spin when car is running?

[spederman]

curious, Out of all the pulley's on the car, which one's actually are run by the motor when its running? What i mean is if there was no belt on the car, and i turned the car on, what pulleys would spin? Is it just the crank pulley and are all the rest just ran off the belt being driven by the crank pulley?

You're right. As the crank rotates it turns the crank pulley and the belt drives the rest.
