Coolant Temperature Sensor – 0051532328 | Mercedes Sprinter Engine Temp Sensor

SKU: 0051532328 - qty 1

Keep your Mercedes Sprinter’s cooling and engine management systems running accurately with this Coolant Temperature Sensor – part #0051532328. This sensor monitors the engine coolant temperature and sends the data to the vehicle’s engine control unit (ECU), which uses that information to adjust fuel delivery, ignition timing, and cooling fan operation. A faulty coolant temp sensor can cause erratic temperature readings, overheating, poor idle quality, rough running, and dashboard warning lights — so replacing it with a high-quality sensor helps restore reliable engine performance and protects your engine from heat-related damage. 

✔ OEM-Equivalent Engine Coolant Temp Sensor

• Designed to match Mercedes-Benz part 0051532328 / A0051532328 for correct fit and function. 

• Measures the temperature of coolant in the engine’s coolant passages and relays accurate data to the ECU. 

✔ Critical for Engine Operation

• The ECU uses coolant temp data to manage fuel mixture, idle behavior, emission controls, and cooling fan activation — all essential for engine efficiency and longevity. 

• Helps prevent overheating by ensuring the ECU and cooling system react properly to rising engine temps.

✔ Durable & Easy to Install

• Built to withstand the high heat and vibration of diesel engine environments.

• Direct-fit sensor that integrates seamlessly into the Sprinter’s cooling system — mounting in the coolant passage typically on the cylinder head or engine block. 

📌 Service Tip: After replacing the coolant temperature sensor, always clear diagnostic trouble codes (DTCs) so the ECU can recalibrate and start using the new sensor data immediately.
