115-4223 Thermostat — Cat

This is an engine coolant thermostat that regulates the engine's operating temperature by controlling the flow of coolant. It is designed to meet precise OEM specifications for opening temperature and flow rate, ensuring the engine maintains optimal thermal efficiency. A malfunctioning thermostat can cause the engine to overheat or run too cool, leading to increased wear and reduced fuel economy.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

An engine running too cool, with the temperature gauge consistently below the normal range, or an engine that overheats rapidly are primary indicators of a faulty thermostat. If the thermostat is stuck closed, the engine will quickly overheat, potentially causing severe damage. If stuck open, the engine may run inefficiently and struggle to reach optimal operating temperature.

Installation Tip

Ensure the thermostat is installed in the correct orientation, with the spring side facing the engine block, to allow proper coolant flow. Do not reuse the old gasket; always install a new one to prevent coolant leaks.

Service Note

Inspect the radiator hoses for signs of swelling or cracking and check the coolant level and condition when replacing the thermostat.
