Now that Castrol doesn't make coolant, what replacement coolant should be used? Just any DexCool coolant?

Yes, GM Dexcool. The one in the car is pinkish. I think Dexcool may come in orange too, depending on the brand, just make sure the bottle spec matches the owners manual spec if not the brand.

...and make sure to use distilled water if buying the unmixed stuff.

Don't know, but I would fly solo with just the antifreeze.

I accidentally unscrewed the bleeder valve in the expansion tank for the coolant. It's the small cap right next to the main cap. The fluid from the top drained back down...is this a problem? Will I introduce air into the system now?

So it looks like I'll have to follow the steps 18-24 to avoid getting air into the system?

Actually, looking more closely, it looks like the coolant just dumps from the top hose into the expansion tank and from the bottom back into the cooling system...therefore I wouldn't be introducing any air just cause I released the valve...right? I mean there's already air in the top half of the reservoir anyway.

Yes you're likely OK as long as the return line was covered.

The link is there just in case.
