Notices

• Before installation, confirm that the part number S1632-E9020 matches your original thermostat and vehicle model.
• Ensure the thermostat opening temperature specification is correct (standard opening temperature: 82°C).
• Always install the thermostat in the correct direction to ensure proper coolant circulation and accurate temperature control.
• Replace the gasket or sealing ring during installation to prevent coolant leakage and maintain sealing performance.
• Clean the thermostat housing and cooling system before installation to remove rust, dirt, or old gasket residue.
• Do not operate the engine without a thermostat, as this may cause unstable engine temperature, poor fuel efficiency, and increased engine wear.
• If the thermostat remains partially open or fails to close completely after cooling, it should be replaced immediately.
• Check coolant level and inspect hoses, radiator, and water pump regularly to avoid engine overheating problems.
• Use only recommended coolant and maintain the correct coolant mixture ratio for optimal cooling system performance.
• Avoid excessive force during installation to prevent damage to the thermostat housing or cooling components.
• After installation, start the engine and check for coolant leaks, abnormal temperature readings, or overheating conditions.
• Regular maintenance of the cooling system can improve engine performance, extend engine life, and reduce the risk of overheating in heavy-duty truck operations.
