Coolant draining is a mess!!

Lately I have been doing some cooling system work, including draining and re-filling a few times.

But it's a mess! The bottom of the radiator has a plug, and when you take it out, the coolant comes RUSHING out and gets everywhere.

Does anyone have any ideas on how to better drain without a mess?

I make a huge mess every time I need to change the thermostat for example.

Re: Coolant draining is a mess!!

You're saying you have a plug? Like similar to an oil drain plug, but smaller? Mine (and all I've seen) has a petcock .. basically a threaded in-line valve that sorta looks like a wing nut. Place a bucket underneath & twist to open .. no muss, no fuss. I think you can even connect a small diameter plastic tube over the end to better direct the flow if needed. If this isn't your setup, take the plug you have to a parts house or radiator shop & get a petcock of the same thread size. HTH.

Get a petcock with a stem that you can slide a hose over to relace that plug.

Re: Coolant draining is a mess!!

1. Yeah, this post has kind of confused me too...
2. I've never seen a radiator with a plug,
3. And NO petcock.
4. That fun <font color="red">HELP</font color> rack at your autoparst store has replacement petcocks.
5. I like In2mud's idea... infact I may use it,
6. It always seems like even with a petcock,
7. That engine coolant always dribbles everywhich way,
8. Except into the drain tub.
9. I gotta think about this one.

Re: Coolant draining is a mess!!

I have a special hose in my tool box I made up just for this because it can be hard to find hose that fits them. So I took a old GM spark plug boot (long straight HEI style plug end the kind that usually have the metal heat shields) then attached a 2 ' piece of hose to that. The plug boot streches easier then most hose and is also a whole lot easier to push on and get back off.

Re: Coolant draining is a mess!!

Thanx all. Yes I do really have a wing nutted plug.

Does someone know the (male) thread size of the threaded hole at the bottom of the radiator where I will put this petcock valve?

Re: Coolant draining is a mess!!

For all fluids you can use an old garbage can lid poke a bunch of drain holes in the center of it and place it over your catch pan. Works real good much larger catch area, I think I read about it in "cheap tricks"
