Product Overview
This cooling-system sensor/switch monitors engine temperature so the gauge, alarm circuit, or control system can respond when coolant temperature rises. A failed unit can produce a dead or inaccurate indication even when the cooling system itself is operating normally.
The sensor installs in the cooling system to provide the temperature signal used by the machine’s gauge or warning circuit. These compact Mitsubishi engines appear in multiple industrial equipment applications, so the engine suffix is an important fitment identifier.
Key Features & Performance
- Cooling-system monitoring: Restores the temperature-sensing point used by the machine's gauge or warning circuit.
- Threaded service replacement: Installs at the corresponding coolant passage when thread size and terminal configuration match.
- Diagnosis-friendly repair: Useful after wiring, connector condition, coolant level, and actual engine temperature have been checked.
Part Numbers & Specifications
- Component: Engine coolant / water temperature sensor
- Engine Family: Mitsubishi L3E
Before You Order
Confirm the full L3E engine model/suffix and compare the sensor threads and electrical terminal to the original part before ordering.
