When i stand next to the passenger fender i can smell antifreeze. it also over heats when i am driving but no loss of coolant on the ground wheather it is just parked or there over night.it has a 2.2 engine with aie condtioning but it does not work

How often does it need to be filled? could be a hose leak or line leak but is burning off the motor or exhaust before it can puddle under car. does your exhaust pipe smell or produce a white steam ( smoke ) in color when running? this would indicate the motor has a bad head gasket or cracked head which is letting coolant burn through the cylinder(s), Double check for leaks, under and above motor. it takes a while for anti-freeze to burn off a hot surface due to its lubricant so wipe any wet area and check again. Also you can pull spark plugs( noting what cylinder each plug came from) a spark plug will be very white or clean in color if that cylinder is burning coolant,which indicates a bad gasket or cylinder leak.
