Auto Spare Parts Gearbox Oil Hose OE 31319278 Engine Oil Pipes for Volvo Auto Parts
This OE-grade gearbox oil hose is tailored for multiple Volvo models, including XC60 (-17), S80 (07-)/S80L, S60 (11-18), V60 (-18)/V60, and V70 (08-). As a key component of the gearbox lubrication system, it adheres to Volvo’s original standards for material resistance, inner diameter precision, and fitting compatibility—ensuring stable transmission of gearbox oil and reliable protection for the gearbox.
Core Components & Functions
Core Component
The hose is constructed from oil-resistant synthetic rubber (reinforced with high-tensile fiber or steel wire) with OE-matched metal fittings at both ends. The rubber material resists high temperatures (up to 120℃) and gearbox oil corrosion, while the fittings feature anti-rust plating for long-term durability.
Core Functions
- Gearbox Oil Circulation: Transfers gearbox oil between the gearbox and oil cooler (or reservoir), ensuring the oil flows smoothly to lubricate internal gearbox components (gears, bearings) and dissipate heat—preventing overheating and excessive wear.
- Leak Prevention: The tight-seal metal fittings and oil-resistant rubber eliminate oil leakage, avoiding oil loss that could lead to gearbox damage or poor shifting performance.
- Pressure Resistance: The reinforced structure withstands the internal pressure of the gearbox oil system, maintaining shape and flow efficiency even under high operating loads.

Installation & Usage Notes
Confirm the hose matches the vehicle’s gearbox type (e.g., automatic vs. manual) via VIN—different gearboxes require hoses with varying pressure ratings. Installation requires adherence to the Volvo service manual:
- Drain the gearbox oil first to avoid spills; disconnect the old hose from the gearbox and oil cooler.
- Align the new hose’s fittings with the mounting points, ensuring no twists (twisting restricts oil flow); secure fittings with OE-specified bolts (torque to 15–20 N·m).
- Refill the gearbox with Volvo-approved oil (follow model-specific oil grade and capacity) and start the engine to check for leaks.
Inspect the hose every 20,000 km: Replace if there are cracks, bulges, or oil stains (signs of wear); avoid contact with sharp underbody parts to prevent accidental damage.

Frequently Asked Questions
Q: How to determine if the bumper bracket needs replacement?
A: Signs of a failing bumper bracket include visible damage or deformation, misaligned bumper panels, unusual noises from the front end, or if the bumper appears loose or sagging on one side.
Q: What should be paid attention to when replacing the bumper bracket?
A: For optimal results, we recommend professional installation. Key considerations include ensuring proper alignment of all mounting points, checking for additional damaged components, and verifying all fasteners are properly torqued to specification.
