I was going to replace my coolant today but I'm having trouble
draining the radiator. There is a little white plug[?] with a tee type
handle that I can't reach on or near the bottom of the radiator on the
drivers side . I assume that's for draining the radiator . I ground a
slot in a socket and could turn it about a 1/8 of a turn and nothing
happened and I didn't want to force it. I saw a plug in the drivers
side of the motor for drainging but didn't pull it out cause I
couldn't do the radiator, I saw what I think is the temp. sensor on
the other side of the block and I guess I could pull that for draining
the other side of the block but what about the rad? pull the bottom
hose? Thanks, Tom

Twist and Pull, and the petcock will open. Carefull, you can pull it out.
Sounds like you did the twist.

I ususally pull the plugs above the oil pan, one is actually a knock sensor.
But your year may be different, its a vortec.

Cheers
