Role of Part 4936408 Oil Level Gauge Tube in Engine Systems

The part 4936408 Oil Level Gauge Tube is a critical component in the accurate measurement and monitoring of oil levels within an engine system. This tube is specifically designed to work in conjunction with the dipstick, gauge, and oil level gauge location to ensure the engine operates within optimal conditions.

Integration with the Dipstick

The Oil Level Gauge Tube interfaces directly with the dipstick, which is a critical tool for measuring the oil level in the engine. The dipstick is inserted into the tube, allowing it to reach the oil reservoir. As the dipstick is withdrawn, it carries a film of oil up the tube, which can then be observed and measured against the marked levels on the dipstick. This interaction ensures that the oil level is accurately assessed during routine checks.

Connection to the Gauge

The Oil Level Gauge Tube also plays a significant role in systems where an oil level gauge is employed. In such setups, the tube is connected to the gauge, which provides a visual or digital readout of the oil level. The gauge relies on the consistent and precise measurement provided by the tube to display accurate oil levels, enabling the operator to make informed decisions regarding oil top-ups or changes.

Oil Level Gauge Location

Positioned at a strategic location within the engine compartment, the Oil Level Gauge Tube ensures easy access for both visual and mechanical checks.
