The cooling system is the lifeline of any heavy-duty truck. As a trusted provider of premium HOWO parts, we supply the Coolant Water Temperature Sensor (Part No. R61540090004), specifically engineered for Sinotruk WD615 and related engine series.

Why is this small sensor so important? It continuously monitors the engine's operating temperature and sends critical data to the dashboard gauge and the ECU. A faulty sensor can lead to false readings, causing drivers to miss overheating warnings, which can result in catastrophic engine failure.
