135 - Coolant coming out overflow tube ONLY after shut off

nrowles · May 13, 2018

I don't think I used the tractor at all over winter. Didn't even start it for probably 3 months. First time I used it this spring I noticed that it was leaking coolant out the overflow tube when shut off. About an oz or two. Has done it the few times I ran it this spring. It does not leak anywhere while running, only after shut down and only out the overflow tube.

What are the things that can cause this and how do I diagnose?

Thanks.

If using it hard, let it cool a few minutes before shutting off.

Makes sense. I was actually thinking it could be the cap. I would say it’s not the coolant level because it didn’t do it last fall and I haven’t added any since then.

If you have room mount a small recovery tank on it? When engine cools down it draws coolant back into radiator.
