Description
If you’ve ever dealt with an engine that won’t warm up on a frosty morning or one that suddenly starts running hot during hay season, you know how critical a good thermostat is. This small but mighty part controls coolant flow to keep your engine at the right temperature, whether you’re firing up that Fiat 110-90 for heavy tillage or depending on your New Holland TD series for daily chores.
What You’re Getting
- Wax-element design that opens and closes automatically based on coolant temperature—no guesswork
- Direct replacement that fits without modifications or adapters
- Built to handle the temperature cycling from cold startup to full-load operation
- Quality construction that resists the chemicals and heat cycling farm engines dish out
Built for Real Farm Work
Whether you’re running a Fiat 80-90 for general farm duties or pushing a 110-90 through heavy field work, these engines work hard under all kinds of conditions. This thermostat also fits New Holland TL Series tractors and TD/TN models that handle everything from loader work to PTO operations. When you’re counting on your tractor for long days of demanding work, proper temperature control keeps you productive instead of stuck with an overheated engine.
Made to Last
Farm engines face brutal conditions—from sub-zero cold starts to sustained heavy loads in summer heat. This thermostat uses proven wax-element technology that responds precisely to temperature changes, staying closed when cold for quick warm-up and opening gradually to prevent overheating. The robust construction handles thousands of temperature cycles and exposure to coolant additives without failing.
Installation Notes
Installation takes about 20-30 minutes once you drain the coolant below the thermostat housing. The spring side faces the engine block, with the wax pellet toward the radiator—installing it backward blocks all flow. While you’ve got the system open, use fresh coolant and check your hoses for cracks or soft spots.
