TOI-20 REPLACING THERMOSTAT

: While searching Walt's Tractor Parts found here @ this site I saw where the thermostat went in the Radiator Hose. I'm kinda new to all this but is this where it was originally located or is this a convenience through the marvels of modern technology. I'm getting ready to rebuild the engine and wanted to know if it had a thermostat in a housing (like a car) or what??

Yup thats where it is. Its an expensive little bugger too, I got mine from Central Tractor. A bit on the primitive side but thats what you got. Before tossing it take it out and see if it looks ok then drop it in a pan of hot water and see if it opens and closes when you remove it smoothly seats well ect. If it is ok keep the old one theyre built like my old caterpillar. Personally I think the hose has more to do with the things leaking by ect and its lots cheaper to change. I put a new temp gauge 9 (generic type) in my TO 20 and it doesn't even really read. It seems to be a lo temp system. So If you get a gauge get one that has graduations very low say 120 deg. It will make you feel better when its wide open as it will be most of the time..... ..... ..
