Thermostat on TO30

Ryan Donde · Aug 1, 2013

Hello All - Anyone run their TO30 WITHOUT the thermostat in the upper radiator hose? When I first purchased my TO30 a couple years ago it did not come with a thermostat in the upper hose. I recently replaced the original radiator and added the thermostat to the upper hose.
I only ask this because I recently got a small leak in the lower tank section of the radiator which may be completely unrelated to the thermostat, but figured I would just ask if its possible the thermostat may have indirectly caused the leak. Any information is appreciated...thank you

You should all ways run with a thermostat to maintain the proper operating clearances that the engine was designed to run with.
A leak in a new lower tank probably has more to do with the quality control of the outfit that made your replacement radiator that it does with the use of a thermostat that was designed to be installed in your tractor.

My TO30 came to me without a thermostat and with no temp gauge. I didn't notice the lack of a thermostat for years, but when I did I put one in. I noticed immediately that the engine finally gets warm in the winter and thus runs better. Summer? It's harder to tell a difference, though I expect it never really got hot enough before. Could your thermostat have caused a problem? I doubt it, but better heads than mine might know better.

We (meaning -guys with old tractors)often have old antifreeze solutions that have sat in our tractors for long periods of time,also older radiators that are getting fragile.

There is a coolant called Evans c ooolant, very pricy , but I think worth it. Why? because it doesn't need to be changed - and its boiling point is around 350 degrees F. Which to us means no pressure build up. You make the cao so it can't hold any pressure - this helps seals and makes leaks easier to avoid, along with the fact you never add water and never use additives. I know of a few friends that run this (have for years) and swear by it. Because it never boiled nor makes gasses ,there are no steam pockets in the block and head -resulting in even cooling - this helps in head gasket wear and overall engine longevity. Look up evans coolant-you guys may find it interesting , its going in my Kubota - Ferguson soon and in my case this winter after its overhaul.
