Default How to drain coolant?

I'm interested in doing the TB bypass, but the how-to mentions draining the coolant beforehand to avoid making a mess when I pop the lines off the TB. What's the best way to do this?

Thanks in advance... :cheers:

drain about 2" from the top of the coolant system... just loosen the drain plug (you know the real work, damned censor).

that should about do it. :thumbs:

I have an '85 and just replaced all the coolant hoses. I turned the plug at the bottom of the radiator just enough to get a controlable trickle, and once it's down a couple inches or so in the radiator, the lines on the TB will be empty :yesnod:

Just wait for the car to cool, open the upper radiator hose, and pour some out onto the driveway, and feed it to the neighbors cats and dogs :lol:

Ouch.....you're gonna catch some crap for that one. I know you're joking, but that one's gonna step on some toes. If one of my neighbors did that to my dog, I would feed him some antifreeze....by whatever means necessary.

:leaving:

Anyhow, back to the topic. Open the drain valve and drain off a few inches. Very simple. And if you use a clean container, you can pour it right back in when you're done.....to ensure that no innocent animals accidentally ingest it. And hose off the driveway too, just to be safe.
