OEM Cross-Reference
This water temperature sensor is a direct replacement for the following OEM part numbers:
15251-73000 – Original Kubota reference for V1505 and D1703 engines
15543-83040 – Alternative Kubota reference for V1902 and V2203 engines
15543-83042 – Updated Kubota reference for V3300 and later engine variants
All three numbers represent the same functional component with identical electrical and physical specifications.
Compatibility
This sensor is commonly used for the following Kubota diesel engine models:
D1703 – 1.7L 3-cylinder industrial diesel engine
V1505 – 1.5L 4-cylinder compact diesel engine
V1902 – 1.9L 4-cylinder industrial diesel engine
V2203 – 2.2L 4-cylinder heavy-duty diesel engine
V3300 – 3.3L 4-cylinder high-torque diesel engine
Applications include construction equipment (e.g., mini excavators, backhoes), agricultural machinery (tractors, harvesters), industrial generators, marine propulsion systems, and material handling equipment. Fitment should be verified against your specific engine serial number and application.

FAQ
Q: How do I verify this sensor fits my Kubota engine? A: Check your engine’s part number against our OEM cross-reference list (15251-73000, 15543-83040, 15543-83042). For engines not listed, compare the physical dimensions and electrical resistance of your original sensor. Our technical support team can assist with fitment verification if you provide your engine model and serial number.
Q: What is the proper installation procedure? A: Installation is straightforward: 1) Drain coolant below the sensor level, 2) Disconnect the electrical connector, 3) Remove the old sensor using a suitable socket, 4) Apply thread sealant to the new sensor, 5) Torque to manufacturer specifications (typically 18-25 Nm), 6) Reconnect the electrical connector, 7) Refill coolant and bleed air from the system. Always consult your engine service manual for exact torque values.
Q: How can I test if the sensor is functioning correctly? A: Use a multimeter to measure resistance between the sensor terminals. At 20°C (68°F), resistance should be approximately 2.5 kΩ. At 80°C (176°F), resistance drops to about 300 Ω. If readings deviate significantly from these values, the sensor may be faulty. Also check for physical damage, corrosion, or loose connections in the wiring harness.
