FAQ
Q: 1. What is the core function of the Cummins 4973373X thermostat?
A: This thermostat uses bimetallic strip technology to precisely control the engine cooling system, operating within a temperature range of 82°C-95°C. It ensures that the 6.7L Cummins 4BT/6BT engine quickly reaches its optimal operating temperature and avoids overheating and wear.
Q: 2. What are the differences between the 6.7L Cummins OEM thermostat and the 6BT version?
A: The 6BT OEM thermostat has a 10% higher valve body pressure capacity and is optimized for the high torque characteristics of the 6BT engine. The 4BT 6.7L version has a more compact structure, suitable for the cooling needs of small and medium power engines.
Q: 3. How are the materials and reliability of this thermostat?
A: It uses a highly corrosion-resistant aluminum alloy shell and synthetic rubber seals. It has passed extreme environment testing from -40°C to 120°C, making it suitable for harsh conditions such as high altitudes and extreme cold, extending its lifespan and simplifying maintenance.
Q: 4. What is the customs code for the Cummins 4973373X thermostat?
A: Engine thermostats are generally classified under liquid pumps and thermostat parts. The specific classification depends on the declared material and intended use. It is recommended to confirm this through the customs pre-classification service before export.
Q: 5. What are the requirements for international shipping packaging?
A: We use waterproof and sealed packaging. For sea freight, we will add desiccant.
