GM GENUINE PARTS engine oil pump pickup tube and screen 12608579 — direct-fit, corrosion-resistant OEM replacement

The GM Genuine Parts 12608579 is the original-equipment engine oil pump pickup tube and screen engineered to restore reliable oil pickup and protect your engine from debris.

This pickup tube and screen assembly is a direct-fit replacement developed and validated by General Motors engineers for compatible Chevrolet, Buick, GMC, and Cadillac powertrains. It combines the correct geometry, mounting points, and filtration aperture to match factory flow characteristics so the oil pump receives a steady supply of lubricant while unwanted particles are kept out of the feed line.

How does this pickup tube and screen protect the engine?

The screen sits at the inlet of the oil pump pickup tube to trap larger contaminants before they enter the pump, while the tube places the inlet at the correct depth in the oil pan to maintain continuous oil pickup during normal driving and cornering. Using an OE-tested part helps maintain designed flow rates and reduces the risk of cavitation or starvation under load.

• Integrated screen mesh catches sludge and debris before pump entry
• Factory-matched tube length and bend preserve designed oil pickup position
• Robust mounting points secure alignment and prevent leaks or movement

Will this part fit my GM vehicle and how accurate is the fit?

Part 12608579 is produced to original equipment specifications for specific GM engine applications. Because GM Genuine Parts are designed and validated by GM, you get the same fit, fastener locations, and clearances as the part installed at the factory, minimizing modification or adjustment during installation.

• Engineered to GM original dimensions and mounting locations
• Compatibility depends on model year and engine; confirm with VIN or parts catalog
• Direct-replacement design reduces installation time and error

What materials and construction details matter for durability?

This pickup tube and screen assembly uses corrosion-resistant metals and a welded or mechanically joined screen to withstand prolonged exposure to engine oil and thermal cycles. OE-level construction resists deformation and maintains a reliable seal at connection points to the pump and oil pan.

• Corrosion-resistant tube and screen for long-term oil exposure
• Precision-formed bends preserve flow characteristics
• Quality welds or crimps ensure screen retention under vibration

How difficult is installation and what should I prepare?

Installation generally requires basic hand tools and access to the oil pan area; depending on vehicle design, removal of the oil pan or partial engine support may be necessary. Follow vehicle service manual torque specs and gasket/reseal procedures to avoid leaks; replacing associated gaskets or hardware during service is recommended.

• Basic tools and torque wrench recommended for secure attachment
• Inspect and replace oil pan gasket or seals as needed during service
• Drain engine oil and clean mating surfaces before installation

Who is this for: This GM Genuine Parts pickup tube and screen is intended for technicians, independent shops, and owners who want a factory-matched replacement for maintenance or repair on compatible GM engines. If you require OE fit, proven materials, and parts validated by General Motors to maintain original lubrication performance, this assembly is an appropriate choice. Always verify compatibility with your vehicle VIN or official GM parts lookup before purchase, and follow recommended service procedures when installing.
