Caterpillar 6I-4955 Water Temperature Regulator: Precise Temperature Control, Protecting the Engine's Lifeline
1. Product Core Information
Model: Caterpillar 6I-4955
Product Name: Caterpillar Genuine Water Temperature Regulator (Thermostat)
Key Function: This water temperature regulator is an intelligent "valve" in the engine cooling system. Its primary function is to automatically control the coolant's circulation path through the expansion and contraction of a wax thermostat. During a cold start, it closes the main circulation path, forcing the coolant to circulate more slowly within the engine, allowing the engine to warm up quickly and reducing wear. Once the engine reaches its optimal operating temperature (typically around 80-84°C), it gradually opens, allowing the coolant to circulate more rapidly through the radiator, effectively dissipating heat and preventing overheating. Its precise temperature control is crucial for maintaining engine efficiency, fuel economy, and reducing emissions.
Maintenance Tips: To ensure long-term, reliable operation of the water temperature regulator, regularly check its opening and closing functions. Use recommended, high-quality coolant (such as Cat® ELC) and keep the cooling system clean to prevent scale and impurities from affecting the temperature sensor. When replacing, ensure the mounting surface is clean and tighten to the specified torque.
2. Product Details
Precise Temperature Sensing and Reliable Actuation: The Caterpillar 6I-4955 water temperature regulator uses high-quality paraffin as its sensing medium. Its precisely calculated expansion coefficient ensures a sensitive and linear response to coolant temperature changes. This sensor actuation method avoids the tendency of traditional mechanical structures to stick, ensuring accurate and smooth valve operation at specific temperatures (e.g., opening at approximately 84°C and reaching full opening at approximately 94°C). The internal spring and valve seat are constructed of corrosion-resistant materials, ensuring long-term reliability and durability in coolant environments.
Precise Temperature Control and Engine Protection: This water temperature regulator is designed and manufactured strictly in accordance with Caterpillar engine thermal management requirements, with its opening temperature parameters perfectly aligned with the calibration of the engine's electronic control unit (ECU). By ensuring the engine quickly reaches and stabilizes at its optimal operating temperature (typically around 80-84°C), it effectively reduces engine wear during cold starts, lowers fuel consumption and harmful emissions, and prevents engine performance degradation or even damage due to overheating. Its optimized maximum opening length (e.g., 11mm) ensures sufficient coolant flow to meet high-load cooling requirements.
Solving Key Pain Points and Ensuring Equipment Uptime: Water temperature regulator malfunctions (such as being permanently open or closed) can directly lead to abnormal engine operating temperatures. If it's always open, the engine will warm up slowly, and prolonged operation at low temperatures will accelerate wear and increase fuel consumption. If it's always closed, the engine is prone to "boiling," leading to high-temperature shutdowns and even serious mechanical damage such as cylinder head deformation and cylinder scuffing. Using this genuine water temperature regulator precisely controls coolant flow, effectively preventing these issues and is key to ensuring stable equipment operation and high uptime.

The main function of the Carter oil filter is to filter the engine oil inside the engine, improving its cleanliness and lubrication. Clean engine oil is supplied to the crankshaft, connecting rod, camshaft, turbocharger, piston rings and other moving pairs to play a role in lubrication, cooling and cleaning, thereby reducing the wear of the engine, enabling it to function at its best and extending the service life of these components.

Just like the blood circulation system of the heart, the oil in the oil pump is also constantly circulating. During this process, many unexpected impurities are often produced, and such unclean substances need to be filtered out by the oil filter element.
