Description
When your water temperature gauge starts acting up or you’re getting false readings, it’s usually the water temperature switch that’s causing trouble. This little sensor is your early warning system for overheating problems—it sends the signal to your dash gauge to let you know if coolant temps are climbing too high. If it’s not working right, you could be driving blind into engine damage, or worse, getting false alarms that shut you down when there’s work to finish.
What You’re Getting
- Precision electrical sensor that gives accurate temperature readings to your dashboard gauge
- Direct replacement that connects to your existing wiring without modifications
- Durable construction built to handle the heat, vibration, and coolant exposure of farm work
- Quick-responding sensor element that alerts you to temperature changes before they become problems
Built for Real Farm Work
This switch is designed for the Ford New Holland TM series and Case MXM series tractors—machines that put in long days running everything from hay equipment to heavy tillage implements. Whether you’re baling hay in the summer heat or pushing through muddy spring fieldwork, these tractors generate serious heat under load, and this switch makes sure you know exactly what’s happening with your cooling system.
Made to Last
Water temperature switches live in a tough environment—constantly exposed to hot coolant with its corrosive additives while dealing with engine vibration and temperature swings. This replacement is built with materials that resist coolant degradation and maintain reliable electrical connections season after season.
Installation Notes
Installing this switch typically means draining some coolant and threading the new unit into the existing location. Use thread sealant to prevent leaks, and it’s a good time to check your coolant level and condition while you’re at it. Test your gauge after installation to make sure it’s reading properly—you’ll want that early warning working when you need it most.
