My 94 Z28 started to smoke under the hood today. It's smells like antifreeze. I checked all the hoses and iall the hoses are fine and all clamps are snug. It;s smoking right under the intake and spraying antifreeze upwards. I just need some other ideas on what could possibly be the problem! PLEASE HELP.

 

Check the water pump's weep hole.

 

thanks for the advice. It was my upper radiator hose
