Just picked up an oem part online for $21 shipped. It'll be here tomorrow.
A couple of questions...
When I swap out the hose, do I need to burp the system? Or can I just loosen the reservoir cap overnight to get any air bubbles out?
Most coolant that I see for sale is the green stuff. Can I use that or do I need to get specific coolant that matches the kind already being used?
I would just change the hose and try to spill as little as possible.. I would put a pan underneath so the coolant doesn't go all on the ground. If the reservoir tank maybe you could drain the tank into a container. I would just refill the reservoir (with new coolant mix), run the car and see if it goes down and more needs to added.
Our cars use Orange DexCool mixed 50% with water. They do sell 50/50 already mixed under the Prestone brand in Walmart. AC Delco brand I think the dealer sells.
Well crap.
I just read this:

I hope I haven't screwed the pooch. I'll drain the coolant tomorrow morning (not gonna drive it for a while anyway). I hope that will be enough.
