i have been looking for the radiator drain valve i cant find it. can somebody post a picture or something that clearly tells me where this valve is. i already taken off the plastic guard. thanks in advance!!! by the way, its a 2003 MC LS

 

i could not find the one on mine, eather. i have a 97 5th gen, so it might be different, but i just loosend the bottem hose on the radiator and let it drain through there. make shore you have a large drain pan under it, though, i can be a little messy.... ifound that out the hard way! good luck

 

well it turns out mine was hidden behind the metal frame of the car. i used a 15mm socket to turn it loose. but thanks any ways. you know , you could call your local chevrolet dealer and ask them. thats what i did. good luck.[8D]
