    I just replaced my factory '98 Z71 factory radiator with a Delphi RA20109, per the Delphi catalog. However, below the overflow tank nipple, there is another, larger nipple that my OEM tank did not have. What is this for and what can I do to make this work...

    Looked at your rad. on the web. Have to get a rubber cap and put a clamp on it.
    That is for older vehicle heater hose.
