ok i know nothing about cars but my 94 civic keeps on overheating. the coolant keeps on leaking out but theres no puddle under the car! what do i do?

 

what do you mean the coolant keeps leaking out?

If you mean it is low, your headgasket is bad/head is warped (would cause white smoke out tailpipe)

If it is overheating on the temp gauge make sure the coolant system was "burped"

Is the overflow can full?
