The Temperature Sensor 385720510 is a water/coolant temperature sensor designed to accurately monitor the temperature of the engine’s cooling system. It helps the engine control system (ECU) measure coolant temperature so it can adjust fuel delivery, ignition timing and cooling fan operation for optimal performance and protection. This sensor is essential for preventing overheating and ensuring efficient engine operation.
Where It Is Used
The 385720510 temperature sensor is used primarily in:
-
Perkins diesel engines including models like 402D, 403C, 403D and 404D series
-
Diesel generators and power units powered by compatible Perkins engines
-
Industrial machinery, construction equipment and agricultural engines where engine temperature monitoring is required
It fits into the engine’s cooling circuit (thermostat housing or cylinder head coolant port) to provide real‑time temperature data.
Key Functions & Features
-
Engine Coolant Monitoring: Measures engine water/coolant temperature and sends data to the control unit.
-
Prevents Overheating: Helps trigger cooling systems and alarms when operating temperature is too high.
-
Optimizes Performance: Data improves fuel economy and combustion control by adjusting engine settings based on temperature.
-
Durable Construction: Brass housing and sealed electrical connector for corrosion resistance and long service life.
-
Direct Replacement Fit: Designed for easy install as an OEM‑equivalent part.
Why It Matters
Without a functioning temperature sensor, engines can run too hot or too cold, reducing performance, increasing wear and risking damage. This sensor ensures proper engine management and lasting reliability.
