Get engine up to operating temp, open drain plug, drain fluid. Tighten plug, add fluid. Approximately 2 gallons.

ok so this is a multiple flush thing..

if i have it right the book says 11.9 qts. so drain, fill with water, run to circulate. repeat till water is clear coming out. then once i know there is only water in the block add 6 its of dexcool and then top off with water should give me the 50/50 mix i need with the water that is in the block.

sound about right?

i just wanted to make sure there weren't any bleeder screws or something i don't know about hidden somewhere.

You have it right. Put the proper amount of straight coolant (6 qts) and top the rest off with water, which will give you the proper 50/50 mix you're looking for. No bleeders.

The 'airlift tool' makes filling the system without air pockets easy, except it costs a bit. I use it all the time in the shop, great tool.

There are 2 drains in the block if you are so inclined.
