• Specification

• Function 

1. Temperature Regulation
During heavy operation, engine oil can exceed its ideal operating temperature range, causing a significant drop in viscosity and lubricating effectiveness. The oil cooler actively dissipates this excess heat by routing hot oil through a series of internal tubes or fins, allowing it to exchange heat with ambient air or coolant. This process ensures the oil returns to the engine at an appropriate temperature, typically between 80–110°C, to maintain consistent lubrication and protect critical engine parts such as bearings and cylinder walls.

2. Viscosity Maintenance
Maintaining the correct oil viscosity is crucial for efficient power transfer and reduced friction. Overheating causes the oil to thin, increasing wear and tear on moving components. By keeping the oil within its optimal temperature range, the cooler helps preserve its viscosity, ensuring smooth operation and minimizing mechanical stress.
