I have a 2007 silverado crew cab, 4.8L, V8. Looking for the coolant drain on the radiator. I noticed a molded spout on the bottom drivers side of the radiator but it's no drain valve. Anybody have a clue where this is located?

Thanks!

 

there may not be one; you will have to remove the lower rad hose instead.

 

Thanks for the reply. I noticed on the back of the radiotor on the drivers side at the bottom there is a molded outlet (drain) of some sort. There is no valve to open/close. Very peculiar if there is no drain.
