Auto Spare Parts Air Ducts OE 31323114 Lower Radiator Spoiler for Volvo V40 2013-2019
This OE-grade air duct (specifically the lower radiator spoiler) is exclusively tailored for Volvo V40 (2013+) and V40 Cross Country models. Mounted below the radiator, at the front underbody of the vehicle, it adheres to Volvo’s original standards for shape, material, and airflow design—ensuring seamless compatibility with the V40’s front-end structure and optimized performance for radiator cooling and aerodynamics.
Core Components & Functions
Core Component
The air duct is constructed from high-impact, weather-resistant thermoplastic (e.g., PP or ABS) with a lightweight yet rigid structure. It features precision-molded contours to match the V40’s underbody, plus reinforced mounting tabs for secure attachment to the front bumper or radiator support.
Core Functions
- Radiator Air Guidance: Directs external airflow toward the radiator core, maximizing cool air intake to dissipate heat from the engine coolant—ensuring the engine operates at optimal temperature, especially during high-load driving (e.g., highway speeds, towing).
- Aerodynamic Optimization: Reduces underbody air turbulence by streamlining airflow beneath the vehicle, lowering wind drag and slightly improving fuel efficiency. It also prevents air from "stalling" near the radiator, maintaining consistent cooling performance.
- Debris Protection: Blocks small road debris (e.g., gravel, leaves) from being drawn into the radiator fins, avoiding clogs that reduce cooling efficiency or damage the radiator.
Compatible Vehicles
Applicable Models | Applicable Years |
V40 (13-) | 2013–2019 |
V40 Cross Country | 2013–2019 |
Installation & Usage Notes
Confirm the duct matches the V40’s trim (standard V40 vs. Cross Country—minor contour differences may exist) via VIN. Installation follows the V40 service manual:
- Safely lift the vehicle (use jack stands for stability) and access the lower front underbody.
- Remove the old duct by detaching plastic clips or screws from the bumper/radiator support (use a trim tool to avoid scratching the underbody).
- Align the new duct’s mounting tabs with the vehicle’s attachment points, then secure with OE clips/screws (do not over-tighten to prevent plastic cracking).
- After installation, check for gaps between the duct and radiator—an even fit ensures proper airflow guidance.
Inspect the duct every 6 months: Replace if cracked or if mounting tabs break (damaged ducts lose airflow control); clean accumulated mud/debris from the duct surface to maintain airflow 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.
