Description

When your tractor’s burning extra fuel on cold starts or you’ve got weak heat in the cab, there’s a good chance your thermostat is stuck open. Running too cool is just as problematic as overheating – poor fuel economy, excessive engine wear, and weak cab heat all point to a faulty thermostat. This replacement thermostat gets your engine up to proper operating temperature quickly so you’re not burning fuel for nothing.

What You’re Getting

Precision temperature calibration for optimal operation – opens at the right temperature every time
Ensures your engine reaches and maintains proper operating temperature for efficient combustion and proper oil flow
Direct replacement that fits without modifications or guesswork
Reliable operation whether you’re doing light loader work or heavy field operations

Built for Real Farm Work

Whether you’re warming up a 6420 before loader work, running a 6620 all day in the field, or depending on a 7320 for winter operations, proper temperature control is critical. These versatile tractors handle everything from hay operations to grain harvest to loader work, and they all depend on reaching operating temperature quickly to perform their best.

Made to Last

Farm thermostats take a beating from temperature swings, vibration, and the demands of long work days. This one’s built to handle the constant cycling between cold starts and full operating temperature. The precision calibration stays accurate through thousands of cycles, so your engine keeps running at peak efficiency season after season.

Installation Notes

Thermostat replacement is straightforward but requires attention to detail. Drain coolant below thermostat level and clean the housing thoroughly. Note installation direction – the temperature sensing element typically faces the engine block. Use new gaskets or O-rings to prevent leaks. Don’t eliminate the thermostat thinking it will help cooling – engines need proper temperature regulation for efficiency.
