Block Drain?

Yes like in the good-ole V8's thay had 1 for each bank of cylinders. Usually located at the very bottom of the block.

Will that drain the block completely? I heard of a drain plug on the water pump too?

I will be replacing the coolant in my son's car soon and would like to get all the info as well.

Thanks

Well you don't need to drain it dry if it isn't contaminated with oil or gas. You can refill with water run until thermostat opens up and drain again then refill with DEX-COOL @ a 50/50 mix. Make sure it is the orange stuff. I use reverse osmosis or distilled water but specifications only require regular tap water.

Correct me if i'm wrong but, When when draining your radiator - Just remove the pitcock(plug) under neat the radiator, close the plug fill with clean or distilled water **preferably** then run it till thermostat kicks in. Fill the coolant reservoir with Dexcool 50/50.

If wanting to completely FLUSH out the system that would require you to add extra step from the top and find the water pump plug by the engine block!

Am I missing anything?

I agree there really is no need to remove all the antifreeze from the car, but the plug on the bottom af the radiator will work wonders in draining down your car.
