Coolant Temperature Sender Sensor for John Deere
The Coolant Temperature Sender Sensor AZ35440 for John Deere measures the engine coolant temperature and transmits the data to the temperature gauge or ECM, helping maintain proper operating temperatures. It is a direct replacement for the AZ35440 part number and is engineered for John Deere 2755, 3029D, and 3029T engines. This coolant temperature sender sensor for John Deere delivers dependable readings under continuous load.
Overview
The Coolant Temperature Sender Sensor AZ35440 is a precision component that converts engine coolant heat into an electrical resistance signal for the gauge or control unit. It is specifically designed for John Deere agricultural tractors and industrial engines, ensuring the operator receives accurate coolant temperature data. This coolant temperature sender sensor for John Deere supports proactive cooling system maintenance and prevents overheating damage.

Good To Know
Q: Can this sensor be installed on a John Deere 2755 tractor? A: Yes, it is designed to fit the 2755 model and directly replaces the original AZ35440 sender, providing the same mounting and electrical interface.
Q: What happens if the coolant temperature sensor fails? A: A failed sender can cause the gauge to read cold, hot, or stay pegged. Replacing it with this AZ35440 sensor restores accurate temperature indication and protects the engine from thermal stress.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
