Product Overview
An engine that takes too long to warm up may have a thermostat stuck open; rapid overheating with a cold radiator hose can mean it is stuck closed. Check coolant level, belt drive, radiator flow, cap, fan, and combustion leakage before assuming the thermostat is the only fault.
The thermostat controls coolant flow as the engine warms, helping maintain normal operating temperature under changing loads. Match the outside diameter, height, temperature marking, bypass design, and gasket arrangement because Kubota engine families can use more than one thermostat.

Model, production date, serial number, connector, dimensions, installed options, and previous repairs can affect fitment. Compare the original component and reference information before purchase.
Frequently Asked Questions
Q: Can removing the thermostat solve overheating? A: No. Running without the designed restriction can create poor warm-up and abnormal coolant circulation; diagnose the system properly.
Q: Should the gasket be replaced too? A: Yes. Use the correct new seal or gasket for the housing unless the listing explicitly shows it is included.
Q: How do I confirm this is the correct part? A: Match 19434-73014, engine specification, thermostat diameter and height, temperature marking, flange, bypass design, seal, and housing depth.
Q: Is this supplied by the original equipment manufacturer? A: No. This is a new aftermarket item. Brand, model, and part numbers are used only to identify compatible applications.
