antifreeze going empty no leaks on floor, engine oil ok

Antifreeze going somewhere! Mechanic says possible head gaskets or intake gaskets, says is common.

loosing Antifreeze and can't find a leak, I can smell it when driving, and see that the antifreeze level is low. add more every few days I need to add more antifreeze. I had someone to look at it and no leak could be found..

Had hard time getting someone to find the problem. Antifreeze on garage floor but could not find where it came from. Seemed to occur after running, and not leaking until car cooled down. Mostly overnight.

Could not find leak. very elusive. Hope water pump fixes problem.
