Depends on what else that belt runs. You didn't list the engine size so I have no way of knowing what other systems are involved. If the water pump is run on the timing belt, the engine will not overheat. If the generator is run on the broken belt, you'll only get up to about a half hour of driving if you leave the heater fan and head lights off, then the battery will need to be recharged. It is common for power steering fluid to be pushed out of the reservoir when you turn the steering wheel a lot with the pump not running. That will make a mess but won't damage the pump or steering gear. Refill the reservoir and let the air bleed out after the belt is replaced.
