247-7133 3408 76° Thermostat for Caterpillar Engine Parts | Diesel Construction

Product Details

Product Overview

This is a high-quality 247-7133 76° Thermostat, specifically designed for use with Caterpillar 3408 diesel engines. As a critical component of the engine’s cooling system, this thermostat regulates the operating temperature by controlling the flow of coolant, ensuring the engine reaches and maintains its optimal temperature range for efficient combustion and reduced wear.

Manufactured by, this thermostat is a direct replacement for the OEM part number 247-7133. It is suitable for a wide range of heavy-duty applications where the Caterpillar 3408 engine is deployed, including construction machinery, industrial equipment, agricultural tractors, generator sets (gensets), marine vessels, and material handling equipment. While this part is designed to OEM specifications, we always recommend verifying compatibility with your specific engine model and serial number before installation.

This component is essential for preventing engine overcooling, which can lead to increased fuel consumption and sludge buildup, or overheating, which can cause severe engine damage. By ensuring the engine operates at the correct 76°C (169°F) opening temperature, this thermostat helps maximize engine life and performance.

FAQ

Q: How do I know if this 247-7133 thermostat will fit my Caterpillar 3408 engine?
A: This thermostat is designed as a direct replacement for the OEM part number 247-7133, which is standard for the Caterpillar 3408 diesel engine. However, due to engine serial number variations and potential supersessions, we strongly recommend checking your engine’s serial number against the Caterpillar parts database or consulting your engine’s service manual to confirm 247-7133 is the correct part for your specific unit.

Q: What are the signs of a failing thermostat in a 3408 engine?
A: Common symptoms include the engine taking too long to warm up (overcooling), the engine running hotter than normal (overheating), fluctuating temperature gauge readings, or coolant leaking from the thermostat housing. If you notice any of these issues, it is advisable to replace the thermostat promptly to prevent further engine wear or damage.

Q: Should I replace the gasket when installing this thermostat?
A: Yes, we always recommend replacing the thermostat gasket or seal during installation to ensure a proper, leak-free seal. The old gasket may be compressed or damaged. While this part listing is for the thermostat only, a new gasket (often part of a separate kit) should be used to guarantee a secure fit and prevent coolant leaks, which can cause overheating and air pockets in the cooling system.
