Grommet Component Usage in Engine Systems

The 4920408 is integral to the proper functioning of several key components within engine systems. Its role is to ensure a secure and sealed connection between various parts, thereby maintaining the integrity of the system.

Integration with the Dipstick

In the context of the dipstick, the Grommet is positioned to create a tight seal around the dipstick tube. This seal is essential for accurate oil level readings. Without a proper seal, oil could leak from the tube, leading to inaccurate gauge readings and potential engine damage due to incorrect oil levels.

Role in the Oil Level Gauge System

The Grommet also plays a significant role in the oil level gauge system. It ensures that the gauge’s components are securely connected and sealed, preventing any oil leakage that could interfere with the gauge’s accuracy. This is particularly important in systems where the gauge relies on a float or sensor within the oil pan, as any leakage could result in false readings.

Ensuring Accurate Oil Level Readings

By providing a reliable seal, the Grommet helps maintain the accuracy of oil level readings. This is vital for the overall health of the engine, as it allows for timely oil changes and prevents the engine from running low on oil, which could lead to severe damage.

Supporting the Gauge’s Functionality

In addition to sealing, the Grommet supports the structural integrity of the gauge system. It helps to hold the gauge components in place, ensuring that they function correctly and provide consistent readings over time.

Conclusion

In summary, the 4920408 is a key component in maintaining the functionality and accuracy of the dipstick and oil level gauge within engine systems. Its role in creating secure seals and supporting structural integrity is essential for the reliable operation of these critical engine components.
