I've got an 02 blazer and I was driving it around and it started to overheat so I stopped and coolant was sprayed all over and I am assuming that it's a hose since it was sprayed but I just can't seem to find where it's broke or what's goin on.. it'd be real helpful if there's anyway to know easier where it's broke or something..

 

Welcome to the forum, you will find a lot help here from many experienced members.Go to a local auto parts store and rent a coolant pressure tester and pressurize the system and look for the leak. Very easy to do and the engine won't be hot. To test you remove the radiator cap and replace it with a cap for you application and add a pump and you will pump it up like you would a basketball. The leak will show itself pretty quick if it was spraying coolant. Good luck.

 

I had a pinhole leak on the underside of one of the smaller hoses from the pump. It sprayed everywhere !
