Engine Oil Cooler Inner O-Ring
Mitsubishi FUSO®

The Engine Oil Cooler Inner O-Ring, with part number 3123903900, is a small but important part of a commercial truck's engine oil cooling system. This O-ring is responsible for creating a tight seal between the engine oil cooler and the engine block, preventing oil leaks and ensuring that the engine is properly lubricated. Without a properly functioning Engine Oil Cooler Inner O-Ring, the engine oil cooler may not be able to effectively cool the engine oil, leading to potential engine damage and decreased performance. Additionally, oil leaks caused by a faulty O-ring can lead to environmental damage and costly repairs. Therefore, it is important to regularly inspect and replace this O-ring as needed to ensure the proper functioning of a commercial truck's engine oil cooling system.
