I changed mine last year...pretty easy and I ended up with about two 5-gallon buckets full of old anti-freeze and a couple flushes. I went ahead and replaced the hoses and thermostat also. Easiest way to drain it is to get a big catch pan and pull the lower radiator hose....alot more comes out than just from the radiator drain. Make sure to use the right anti-freeze and make a 50/50 mix before you start dumping it in, don't mix colors. Also, use at least distilled water. I used the water from our reverse osmosis filter that we use for our saltwater/reef aquarium. It's a lot more pure than even distilled water but of course not everyone has one of those...dont just use hose water except for just flushing the system.
Theres a recycle place nearby that takes used oil, batteries, antifreeze, etc. They took my old coolant no problem. Don't forget to clean out and replace the coolant in the overflow container too.
