Auto Spare Parts Left Headlight Bracket OE 30763433 Headlamp Bracket for Volvo XC60 -17
The Hose, Output (Engine Oil Cooler Water Pipe) (OE: 30774514) is a key fluid transfer part for Volvo’s engine cooling system, compatible with multiple sedans, estates, and SUVs. It connects the engine oil cooler to the radiator/coolant reservoir, acting as the "output channel" to send coolant (warmed after absorbing heat from engine oil) back to the main cooling loop. This ensures engine oil stays at an optimal temperature, avoiding reduced lubrication efficiency and engine wear caused by overheating.
Crafted as an OE-grade component, it uses a multi-layer composite structure:
Inner layer (NBR/EPDM rubber): Resists coolant chemicals, oil, and high temperatures (up to 130°C).
Reinforcement layer (braided polyester): Withstands system pressure (up to 15 PSI) to prevent kinking/expansion.
Outer layer (heat-resistant EPDM): Shields from engine bay heat, debris, and UV damage. Its pre-formed bends and OE-matched end fittings fit seamlessly with factory ports, eliminating leaks or flow issues common with generic hoses.
Core Functions
Facilitate Coolant Recirculation: Transports coolant from the engine oil cooler back to the main cooling system (radiator/reservoir), completing the coolant loop. This ensures the oil cooler always has a fresh supply of cooled coolant to absorb oil heat, maintaining engine oil at an optimal operating temperature (typically 80–110°C).
Withstand Under-Hood Stress: The multi-layered construction resists chemical degradation (from coolant/oil), high temperatures (from engine and exhaust), and physical wear (from vibration or debris), preventing hose cracking, swelling, or rupture—failures that would disable the oil cooler and lead to oil overheating.
Maintain System Pressure: The reinforcement layer prevents the hose from collapsing under vacuum or expanding under pressure, ensuring consistent coolant flow rate. Stable flow is critical for the oil cooler to function efficiently: insufficient flow leads to inadequate oil cooling, while excessive flow wastes energy from the water pump.

*For 100% fitment accuracy:
Confirm the vehicle’s engine type via VIN—variants with turbocharged vs. naturally aspirated engines may have different oil cooler configurations, and this hose is calibrated for specific engine cooling system specs.
Reference the vehicle’s official service manual to verify the hose’s exact routing (under-hood path) and torque specifications for end clamps—over-tightening can damage the hose’s inner layer, while under-tightening causes leaks.
Note that coolant hoses should be replaced in pairs (input + output) if aging (e.g., hardening, cracking) is detected—mismatched hoses may have inconsistent flow rates, reducing cooling system efficiency.*
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.
