happening to all those at once. Suggest disconnecting the battery for a bit. As for the coolant it sounds like an overheat issue and discharge is overflowing the coolant tank bleed hole. Did you check the level in the overflow bottle? As for the PS look into the belt and see if it is slipping. Make sure you only add the correct fluid and it is not power steering fluid but auto tranny fluid, look in your manual for the specific type.
