'07 Yukon XL - Radiator Drain?

[BSarteSr]

I am going to be flushing out my cooling system and need to drain it. There is a hole down the bottom of the radiator on the driver side, I put my little finger in it, don't feel anything?

How do you drain the cooling system?

Disconnect the lower radiator hose.

No drain, you just got to yank the hose and make mess. If you do a lot of your own work I would invest in one of these. You can use it to suck the coolant out from top to bottom working through the overflow tank, overflow hose, hose to the water pump, working your way down into the water pump housing itself. Then pull the lower hose off the pump and suck it the rest of the way down, if you follow what I am trying to convey. I use this every time I do any fluid retrievals. Works great.
