My Farmall 140 radiator is leaking

Sun Jun 01, 2008 8:20 pm

My radiator is weeping on the front side, at the top seam. I intended to remove it and take it to the radiator shop. This is the problem, I can't find the drain cock to empty the radiator or is there one to start with? The potatoes are waiting, help!

There should be a drain plug in the block under the carburetor

And a second one, probably in the inlet elbow.

Front lower left find the lower hose going from radiator to engine. There is a cast metal piece with a hose on radiator side, and one on the engine side. There is a hole in the frame just below the rear elbow of this cast metal piece. Look up through this hole and find a 7/16" square head threaded plug which is the radiator drain. Remove this plug and the radiator will drain. Be warned it may by hard to get out. I drained 3 tractors recently through this plug and had to use a 'bolt out' tool I got at Sears. Replaced all 3 plugs with brass plugs.
