Where is the radiator drain plug on a 2004 Monte Carlo!!?? I have looked and I don’t see anything. I read it was in drivers side but that isn’t helping me. Any chance someone has a diagram or a pic? Thank you.

 

Yellow thing on the bottom left of this pic (note thats the driver's lower from the engine side). This is an aftermarket radiator, stock ones are usually black like the surrounding plastic.



BUT - I wouldnt touch it unless the radiator is pretty new. If its an original radiator, I would absolutely not even consider it. Those plastic end tanks get brittle with age and heat cycles and its very easy to break them (which ruins the radiator).

I've personally broken 3 (only 2 on w bodies though), so I don't use them at all anymore on any car. Instead I slice a hole in the lower radiator hose at the lowest spot (so you have a semi controlled drain), and then I slice the lower hose off the radiator (instead of yanking the hose / risk breaking the radiator connection off).

TBH if youve got the cooling system drained anyways, I'd always stick on new hoses while its apart. They're cheap and its far easier to do it now than have one fail between changes.
