Overflow tank

Postby GBuford4372 » Sat Jul 25, 2020 5:19 am

Aaron/Winston, could you tell me if the 2010D is SUPPOSED to have a radiator overflow tank?

Thought so. What if it's not on there?

Not the end of the world. As long as you maintain a good level in the radiator you can run without it. They are designed for expansion. As the coolant heats it sometimes pushes it into the bottle. When the engine cools the coolant is sucked back in.

So here's my question. There is a tube hanging out of the radiator where it probably should be hooked to the overflow. Would it be sucking air in the radiator if it's just hanging there?

Theoretically your radiator level would get only so low that when running hot it would be full and then when cooling down the level would just go down a little. So in theory I guess it would suck in some air but expel it when hot.

Ok. The reason I asked is I see a bubble every now and then and I want to rule out gasket leak

But my thermo appears to be stuck open because as soon as I start tractor, it starts circulating

For what it's worth I have made overflow bottles. Just take whatever size and shape plastic bottle you have that has a screw on lid. Drill a hole in the lid the size of your hose, stick it in, put a tad of coolant in it, tie the jug on some where. Then you can watch for bubbles or over flow.
