This thermostat is a direct replacement for the following OEM part numbers:
Q1: How do I verify if this thermostat fits my Kubota D902 engine?
A: Check your engine’s serial number and existing thermostat part number. This thermostat is designed for standard Kubota D902 engines. For non-standard variants (e.g., D902-T turbo), please verify the housing diameter and gasket type. If in doubt, send us a photo of your old part for confirmation.
Q2: What is the correct installation procedure for this thermostat?
A: Drain coolant to below thermostat level. Remove the thermostat housing, replace the old thermostat with the new one (ensure the jiggle pin is oriented correctly, typically at 12 o’clock position), replace the gasket, and torque the housing bolts to manufacturer specifications (typically 12-15 Nm). Refill coolant and bleed air from the system. Test for leaks after engine warm-up.
Q3: What are the signs of a failing thermostat on a Kubota D902 engine?
A: Common symptoms include: engine overheating or running too cold, slow warm-up, fluctuating temperature gauge, coolant leaks near the thermostat housing, and reduced heater performance. If the thermostat sticks open, the engine may not reach optimal operating temperature, increasing fuel consumption and wear. If it sticks closed, immediate overheating can occur. Replace if any of these symptoms appear.
