    best Radiator  you can get for your car.
  

*by B***G on Reviewed in the United States on December 18, 2017*

This radiator fit and looked exactly like the one it replaced little hard to replace the radiator because of the cramped engine bay in a chevy cobalt not the radiators fault this is a high quality radiator well worth the difference in price to get the best for your cooling system if you need a radiator for your cobalt this is the best one to buy. fits and looks exactly like stock because it is the factory replacement you cannot go wrong with acdelco.
