Coolant Temperature Sensor for Case Magnum Series Tractors SKU: QT400090

A failing coolant temperature sensor leaves you flying blind when engine temperatures climb—your gauge won't show accurate readings, and warning lights may not activate until overheating damage is already occurring. This replacement temperature sensor ensures your Case Magnum's monitoring system gives you the accurate readings you need to catch problems before they turn into expensive repairs.

Why Accurate Temperature Monitoring Matters

• Precision-calibrated resistance values provide reliable temperature readings throughout the operating range
• Durable construction withstands constant exposure to hot coolant, pressure cycles, and corrosive additives
• Direct replacement design eliminates guesswork with proper thread fit and electrical connections
• Early warning capability protects against catastrophic engine damage from undetected overheating

Your Magnum series tractor generates serious heat under load whether you're running a large planter in spring, pulling heavy tillage equipment, or operating hydraulic implements all day. These sensors live in a harsh environment - immersed in hot coolant with its corrosive additives, subject to pressure cycles, and exposed to temperature extremes. When the sensor fails, you lose critical early warning that lets you shut down safely before minor issues become major problems. With over 55 years of experience, S&H Parts understands the importance of reliable temperature monitoring for keeping your equipment running productively.
