Auto Spare Parts Gearbox Oil Hose OE 31319281 Output Coolant Hose
for Volvo Cooling System
This OE-grade gearbox oil hose (specifically the output coolant
hose) is tailored for multiple Volvo models, including XC60 (-17),
S80 (07-)/S80L, S60 (11-18), V60 (-18)/V60, XC70 (08-), and V70
(08-). As a key component of the gearbox cooling system, it adheres
to Volvo’s original standards for material heat resistance, oil
compatibility, and fitting precision—ensuring stable circulation of
gearbox oil to the cooler and reliable protection for the gearbox.
Core Components & Functions
Core Component
The hose is made of high-temperature resistant synthetic rubber
(reinforced with steel wire or high-tensile fiber) with OE-matched
metal fittings at both ends. The rubber material withstands
temperatures up to 130℃ and resists corrosion from gearbox oil,
while the fittings feature anti-rust zinc plating to prevent
under-hood moisture damage.
Core Functions
- Gearbox Oil Cooling: Transfers hot gearbox oil from the gearbox to
the oil cooler (the "out" flow direction), enabling heat
dissipation to avoid oil overheating—preventing reduced lubrication
efficiency or gearbox component wear.
- Leak-Proof Seal: The precision-machined metal fittings form a tight
seal with the gearbox and cooler interfaces, eliminating oil
leakage that could lead to oil loss or system failure.
- Pressure Resistance: The reinforced structure handles the internal
pressure of the gearbox oil system (up to 5 bar), maintaining shape
and consistent oil flow even under high operating loads.

Installation & Usage Notes
- Confirm the hose is for the output coolant flow (distinguished from
"in" hoses by length/fitting angle—do not reverse); verify
compatibility with the vehicle’s gearbox type (automatic/manual)
via VIN.
- Installation steps (per Volvo service manual):
- Drain gearbox oil first to avoid spills; disconnect the old hose
from the gearbox (oil outlet) and cooler.
- Align the new hose’s fittings with mounting points—ensure no twists
(twisting restricts flow); secure fittings with OE bolts, torquing
to 18–22 N·m.
- Refill with Volvo-approved gearbox oil (follow model-specific
grade/capacity), then start the engine to check for leaks.
- Inspect every 20,000 km: Replace if there are cracks, bulges, or
oil stains (signs of wear); keep the hose away from sharp underbody
parts or hot components (e.g., exhaust pipes) to prevent 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.
