Product Overview

The thermostat regulates coolant flow as the engine warms up and helps maintain the intended operating temperature. A thermostat stuck open can cause slow warm-up, while one stuck closed can contribute to overheating.

Kubota parts information shows 19203-73010 on G2000/RTV500 applications and later replacement numbers for the same thermostat family. The exact machine and serial number should be checked before ordering.
