235-4959 Thermostat 235 4960 With Gasket — Cat 3044C 279C

This is a thermostat assembly designed to regulate engine coolant temperature within the specified operating range for CAT engines. It ensures optimal performance and prevents overheating by opening and closing to control coolant flow to the radiator, meeting stringent OEM quality standards for durability and precise temperature control. A failed thermostat may cause the engine to run too cool, leading to poor fuel economy and increased emissions, or overheat if stuck closed, indicated by a rising temperature gauge and potential steam from the engine bay.

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

The first sign of a failing thermostat may be inconsistent engine temperature readings on the gauge. If ignored, the engine may consistently run too cold, leading to reduced efficiency, or overheat if the thermostat is stuck closed. Prolonged operation outside the optimal temperature range can lead to increased wear on engine components.

Installation Tip

Ensure the engine block mating surface is thoroughly cleaned of any old gasket material or debris before installing the new thermostat. Avoid overtightening the thermostat housing bolts, as this can distort the housing and cause leaks.

Service Note

Inspect the radiator hoses and coolant for signs of degradation or contamination when replacing the thermostat.
