Description
If your Fendt’s been running cooler than it should or taking forever to warm up, chances are your thermostat is stuck open. On the flip side, if you’re seeing higher temperatures than normal or worse fuel economy, it might be sticking closed. Either way, your engine isn’t running at its optimal temperature, and that means more wear and wasted fuel. This replacement thermostat gets your cooling system back to where it needs to be.
What You’re Getting
- Precise temperature control that opens at the factory-specified temperature for your Fendt
- Quality wax pellet mechanism that responds reliably to temperature changes
- Full-flow design that minimizes restriction when open for maximum cooling
- Durable construction built to handle the demands of modern agricultural work
- Direct OEM replacement that installs without modifications
Built for Real Farm Work
This thermostat fits a wide range of Fendt tractors from the compact Farmer 300 series utility tractors up through the powerful Favorit 800 series machines. Whether you’re running a 400 Vario for dairy operations, a Favorit 700 for row crop work, or an 800 series for heavy tillage and harvest support, this is the same thermostat that keeps your engine running at peak efficiency.
Made to Last
Fendt engines work hard, and their cooling systems need parts that can keep up. This thermostat uses proven wax pellet technology that expands predictably at the right temperature, opening the valve to let coolant flow to the radiator. The materials resist corrosion from modern coolant additives and handle the temperature cycling that comes with real farm work.
Good to Know
Installation typically takes 30-45 minutes. You’ll need to drain some coolant first – no need to empty the whole system, just below the thermostat housing. Clean the gasket surfaces thoroughly before installing, and make sure the thermostat goes in the right direction – the spring side faces the engine. After installation, fill slowly to prevent air pockets and let the engine run until the thermostat opens to ensure proper bleeding.
