Engine Thermostat with Gasket for Kioti CK, CS, CX, DK, DS, and K9 Series Tractors and UTVs SKU: E5800-73011-WE5500-73272

A failing thermostat creates serious problems—engines that run too cold burn fuel inefficiently and develop oil contamination, while stuck-closed thermostats cause dangerous overheating that can crack cylinder heads or seize internal components. This genuine Kioti thermostat and gasket kit maintains precise operating temperature for optimal performance and engine protection.

Why Genuine Matters

• Exact opening temperature prevents fuel dilution and ensures complete combustion
• Factory-matched gasket eliminates coolant leaks and air pockets
• Built to handle the thermal cycling of diesel engines over thousands of hours
• Proper fit prevents bypass flow that compromises temperature control

Don't let a failed thermostat turn into an expensive engine rebuild. This genuine Kioti replacement restores factory temperature control across your CK, CS, CX, DK, DS series tractors and K9 UTVs.
