Role of Part 3979393 Lubricating Oil Filter Head in Engine Systems

In the orchestration of engine systems, the lubricating oil filter head, designated as part 3979393, assumes a significant role. This component is integral to the efficient functioning of the lube oil filtration system, ensuring that the oil circulating within the engine remains clean and free from contaminants.

Integration with Lubricating Oil Filter Cover

The lubricating oil filter head interfaces directly with the lubricating oil filter cover. This connection is essential for maintaining the structural integrity of the filtration system. The head provides a secure mounting point for the filter cover, which encases the filter element. Together, they form a sealed environment that prevents unfiltered oil from bypassing the filtration process.

Functionality with Engine Oil Cooler

In conjunction with the engine oil cooler, the lubricating oil filter head plays a part in maintaining optimal oil temperature. Clean oil, filtered by the head, flows more efficiently through the cooler, enhancing heat exchange. This synergy ensures that the oil remains at an ideal temperature, which is vital for reducing engine wear and improving performance.

Lubricating Oil Filter Head’s Contribution to System Efficiency

The lubricating oil filter head is designed to facilitate the smooth passage of oil from the sump to the filter element.
