Description

When your temperature gauge starts acting up or your engine warning light isn’t working right, it’s usually this little temperature sensor that’s gone bad. This sensor monitors your coolant temperature and alerts you when things start getting too hot, giving you time to shut down safely before expensive damage happens. A failed sensor means you’re flying blind when it comes to engine temperature—and that’s a recipe for major trouble.

What You’re Getting

Accurate temperature monitoring that responds quickly to changes in coolant temperature
Reliable electrical connection that won’t corrode or fail from exposure to hot coolant
Direct replacement that works with your existing wiring harness and dash gauges
Quality construction designed to handle the constant heat cycles and pressure changes

Built for Real Farm Work

Whether you’re running a 6420 through long harvest days, using your 5820 for loader work, or depending on a 7320 for heavy field operations, this sensor keeps track of engine temperature so you know when cooling system problems are developing. It fits John Deere tractors from compact utility models up through high-horsepower row-crop machines that work hard in all conditions.

Made to Last

Temperature sensors live in harsh conditions—immersed in hot coolant with corrosive additives and exposed to constant temperature swings. This replacement uses materials specifically chosen to resist coolant degradation while maintaining reliable electrical function throughout its service life.

Installation Notes

Installation requires draining coolant below the sensor level, removing the old unit, and threading in the new sensor with proper sealant. This is also a good time to check your coolant condition and top off if needed. Always test your temperature gauge after installation to make sure everything’s reading correctly.
