catch the coolant when draining Farmall 200

[jdsingleshot]

The coolant system drain on my Farmall 200 is in a place that will splash the coolant all over when draining. It's good newish coolant that I want to save. How can I direct it to/through the hole in the center of the casting? (Please see photo.)

Replace the pipe plug with a nipple and cap. A little tough to do with coolant in the system but if you’re quick enough you won’t lose too much. Guys use a shop vac to put a vacuum on transmission housings. Not sure how that would work on a radiator though.

On my BN, what I did was to take a 16 oz/ 1/2 liter plastic soda bottle and cut the bottom off at an angle to fit up in there and placed a drain pan underneath. I still lost some coolant and made a mess but I was still able to catch maybe 3/4’s of it.

I added these fittings afterwards to make a better drain.

Thanks to both. I'm sure either of those methods will work. I think I'll try both at once. 8-)

Route a hose up thru and catch what you can -- will need to hold the hose over the plug hole with your hand

Get a moldable funnel.

Tried that on a 1070 a few weeks ago so I could change a heater hose. Didn't work to good. Sucked a bunch of antifreeze into my vacuum.

Yeah , too much volume of air will pull the liquid with it -- you can use a shop vac , but need an orifice to slow down the air 

I used an air powered vac in the shop -- air nozzle on a venturi basically -- really handy for pulling coolant and oil from head bolt holes and tops of pistons

Cheapie plastic toddler pool. About 4 feet diameter. Open and let it run.

Instead of a cap on the pipe nipple, I installed a petcock on my Super C and 200. Makes it easy to drain and no mess. I just turn the wheels to the right and put a funnel with a hose in the gap of the tires with the hose in a bucket.
