There's a drain **** on the left (driver's) side of the radiator, with a hose attached. You are supposed to turn the hose down and open the drain.

Thanks for the response
But I was referring to the ones on the underside of the engine blocks...do these trucks not have those?

I have an 03' with a 34" radiator and it has NO drain ****. I pull the lower radiator hose to drain mine and it does make a for a messy job. GM saving a few cents where ever they think they can squeeze it from.

There is a brass plug on the engine with a female hex. I can't remember the size for sure, but it is big. I think it is 17 mm. I don't remember the location, but it is there.

The plug in the engine is on the left side of the block near the PS pump.

That big brass plug can be a bear to remove too. I had to chisel mine out in the LQ4 I'm rebuilding right now.
