How to locate and remove my thermostat on b7100 kubota hydro 4 wheel?

Haz:
I have a B7100 tractor as well and to my surprise it has a water pump and a thermostat. Apparently, the vast majority of these tractors had neither but relied instead on a thermosiphon system in which the cooler water displaces the warmer water. My engine's thermostat (as you are looking at it) is on the upper right and has a small wire wrapped hose connecting it to the water pump. On my tractor I have 2 fan belts, I think this might be one of the identifiers in determining if yours has a water pump/therostat set up or the thermosiphon. As far as I can tell the rad is really subject to clogging and must be kept clean.

Cheers, Erik
