Can I get some suggestions? No leak origination is noticeable however keeps running out of antifreeze. What's wrong? Its running hot.

 

Can't tell you where leak is but it could help if you included model and year of your car - also how much it is leaking. Radiator shop?

 

Check the obvious, the radiator cap. If may be bad, permitting the anti-freeze to evaporate or boil out?

 

Simple test: have someone stand behind the car and turn it on, look for bluish smoke from the tailpipe. Puff of white is normal (water vapor). Then, drive until the engine is warm/hot (15-20 miles) without A/C on. Shut off the engine, and open the hood. Listen for any hissing or bubbling sounds. DO NOT OPEN THE RADIATOR!

A sweet-smelling smoke from the tailpipe usually means a head gasket or cracked head (big $$$). Hissing from the radiator is pretty easy to fix, buy Bars Leak (under $10) - either Copper or Aluminum will seal the leak perfectly.
