Yup - that'* the plug! Fun to find, huh?

If you want to be sure on getting everything cleaned out that way, I'd suggest doing it with the thermostat removed so the water can run through the entire system. You could still have a fair amount of Dex in the block.

what about the heater core?

It should have taken care of the heater core during the process. If you want to be absolutely certain, remove the hoses to the heater core from the top of the tensioner assembly and run water directly through those hoses.

ok im confident I got all the dex, i opened the T-fitting during the flush and had clear water rush out the hole. I also flushed from the T-fitting. DIE DEX DIE

i plan on putting 2 gallons Prestone Extended Life (yellow stuff) and then topping it with water, sound good?

The cooling system is about 13 quarts, so 8 quarts (2 gallons) will give you a bit over 60% coolant. Maximum is 70% - so you should be fine.

I find the easiest way to drain the coolant is to insert a 3/8 clear plastic hose inside the rad thru the cap opening all the way to the bottom of the rad and then syphon it out into plastic jugs for recycling.............or feeding to the neighbourhood dogs.

Siphoning is an awesome idea! I never thought of that.

DEX is bad == it makes my reservoir have a lot of deposits and ugly looking. (tried cleaning, but it'* very hard)

Speaking of coolant hitting the ground... anyone know why there was coolant running through part of the throttle body when i cleaned it earlier today?

jbmark, DEX is doing more than just dirtying your reservior. If it does that, it'* turned acidic, and is eating your LIM gaskets.

The coolant path is supposed to flow through the TB. All of ours do, as nearly every other brand of car out there.

It'* to prevent icing of the throttle plate and shaft in cold conditions.
