Hi guys I'm looking to flush my radiator on my 2003 Monte Carlo SS and I'm having a hard time locating the drain plug. Someone told me it is on the left side of the radiator and requires a 19mm socket. Do i have to remove the black plastic air duct?? Can someone tell me where exactly its at. Thanks a bunch

 

iirc there isn't one. I know my '97 Grand Prix has one on the bottom right when facing the car. I think on my Monte I just disconnected lower coolant line to drain it.

 

On the engine side of the radiator, bottom driver's side. A pain to get to.

 

on my 96 Z34 it is on the pass side bottom.

i wouldnt advise using them though... i have heard too many stories of the plastic plug breaking. just disconnect the rad hose as it will drain faster anyway.

 

Okay so Im probably just gonna remove the hose then. I still need to take off the plastic air duct I believe, Also I believe the hose is on the passenger side?
