B water coming out of radiator overflow

I've got a 5' mower on my B tractor and after I start mowing for about 15 to 20 minutes I start to see water coming out of my overflow tube along side my radiator. After mowing about 45 minutes my heat gauge is just about in the red and I turn off the tractor, let it cool down, add water and do it all over again. I got the tractor from my brother and he said he had the radiator "boiled" out and cleaned. Should I take the radiator to another shop or what else could cause this to happen? This is my first Allis tractor and I want to get it in as good as running condition as I can. Any help would be greatly appreciated. Thanks in advance.

Does it do this when your not mowing, if it does you might be geting compressoin from one of the pistons, causing it to build upp pressure and pushing the sping open on the radator cap leting it leak, this might be caused by a busted block or sleeve

All of the previous suggestions are good. However, there are some other things you should look at. I had this exact same problem with my B, 5' belley mower, and found that as I mowed, dandelion fluff and dried grass would pack up on the front of the radiator and block the flow. When the tractor was shut off, the stuff might fall down, or I would gently blow the radiator out from the back, then push the stuff out the bottom.

Do you have shutters on the radiator, or any other cover, and if so, are they open.
Running with excessive ignition timing will cause overheating.
Running lean will cause an overheat, richen the carb a bit, and check for vacuum leaks at the carb to manifold and manifold to head or a cracked manifold. Best way is to mist water around the connections and listen for the engine to drop RPM. Using ether por carb cleaner, etc., will work, but since the intake and exhaust manifold are one, it tensd to light off and burn up the machine. Gasket leaks are not unusual on these machines.

The tractor that I use to mow with has a screen in front of the radiator and still plugs up in the finns with small particals of dry grass and fuzzys two or three times a summer. I wash it out with a water hose from the inside through the fan blades. I had to take it off once so I could use air with water.

1) Check to be sure you can see thru the fins, many radiator shops now don't use "real" radiator paint, and they almost fill the fin spaces

2)After running a while, shut down the engine and feel the top vs the bottom of the radiator, you should be able to tell the difference in heat

3)Undo your bottom hose and pour a gallon of water thru the fill neck and see if it rushes right out

4) pull the thermostat and do a quick check in a pan of hot water to see if it's working

5) Also with the radiator low on water, and with the cap off, do you see water movement, showing the waterpump is working?

6) with the cap off and engine running, do you see a lot of bubbles comming up? One of the signs of a leaking head gasket.

Just a few things you can try that don't cost money.....
Good Luck

Antifreeze in a low pressure radiator can also cause a boil over, due to the lower boiling point of alcohol.

I agree with all of the first posts. PSI Check the radiator cap- check the timing specs on the engine- mow early in the morning while its cool, we live in the desert and it makes a big difference here. check fan belt tension, 1/2" deflection...hope this helps..Andy

Today's Featured Article - Madison's County - by Anthony West. Philip Madison has been a good friend of mine for quite some time. He has patiently suffered my incessant chit chat on the subject of tractors for longer than I care to remember, and on many occasions he has put himself out, dropped what ever it was he was doing, to come and lend a hand cranking handles, or loading a find onto a trailer. Although he himself has never actually owned or restored a tractor, he was always enthusiastic and always around helping with other peoples projects. ... [Read Article]
