 Radiator Fluid Under Tractor

Yesterday I notice a small amount of green fluid (radiator fluid?) under my TC33D tractor.
The tractor hasn't been used in a month. There were no known problems with leaking
fluid before this. The tractor has been in a secure garage (nonheated) since its last use
in November. What is this?

 Radiator Fluid Under Tractor

Sometimes in cold weather, the rubber hoses contract enough to make the hose clamps loose, allowing coolant to leak out. If you cannot actually see where the fluid is coming from, I would tighten all hose clamps and see if that cures the problem. Another possibility would be a leaking water pump seal, radiator or gasket. If you can't pinpoint the leak, have the cooling system pressure tested. Kenny

Yes, tighten the clamps and inspect the hoses. I'd also note where the leak was in relation to where the tractor was parked to help locate the leak, and maybe watch for drips after using the tractor. The pressure in many systems increases when an engine is shut down so that's a good time to look for leaks. If the leak is coming from an over-flow hose, there's a chance the rad cap is bad.

I used to use liquid laundry bluing to find cooling system leaks. However, I don't know if bluing is still available or how it would be with modern coolants.

I think some automotive rads don't use soldered-in tubes. These rads may leak a bit when sitting around during very cold weather. For such a rad, it's probably easier to top up the coolant than to replace the rad.

I recall some kind of a bypass valve on the frame on the right side towards the front of the tractor. I believe there was a discharge port on it as well (don't have the tc here to check for you). May want to look at that, I recall N/H having problems with some of those but it I don't recall exactly what it was. Take a look at the database on this site and you can problably find it. Then again, it may just be a loose clamp as mentioned.

I agree with cutter. My neighbor has a New Holland and he has replaced a leaky discharge port twice under warranty. He now keeps a spare on hand.

I finally figured out that the leak is coming from a pipe fitting
screwed into the engine block. This is on the right side of
the tractor and has a small (1/4 inch ?) hose clamped to it. The
hose appears to run to a drain valve at the bottom of the tractor and
then to the bottom of the radiator. The tractor is still under warranty.
Should I call the dealer up and have him fix it or just tighten the
fitting myself?

Sounds like a good excuse to go down to the dealer and play with all the new tractors. Your dealer is probably lonely this time of year anyway. Sounds like the same part my neighbor keeps replacing on his 1920. Problem with doing it yourself is if you break it, you'll lose all your coolant while you race to the dealer for a new one. (if its the port)

My TC 33 D was leaking antifreeze from the same port in the right side of the block. I snugged it with a wrench and it quit leaking. It will be project to remove and reseal as it is very dificult to get a wrench on. Looks like a special socket with one side cut away is needed to do it right.

I know what you are talking about Millstone. Our local NH dealer does not have the special tool to tighten or replace the port or valve. My neighbor did some cutiing and grinding to a socket and made his own. His port has been replaced twice. It's 18 degrees here in Michigan. Too cold for anything but yapping about tractors.

Mrwurm, 18 degrees in Michigan? I wish you'd kept that cold weather up there instead of sending it down here. It's 13 in the middle of Texas this morning.Laughing out loud
