Auto Parts Sound Absorber OE 31298731 Engine Cover Insulation Board for Volvo S80 S80L XC70 V70


The Sound Absorber (also referred to as Engine Cover Insulation Board or Engine Cover Lining, OE Number: 31298731) is a specialized thermal and acoustic component exclusively engineered for select Volvo models. Constructed from a multi-layered composite material—typically a combination of heat-resistant fiberglass, closed-cell foam, and a protective polypropylene outer layer—it balances superior sound dampening, heat insulation, and durability.

Designed to mount directly to the engine cover or the upper section of the engine bay, this component addresses two critical needs: reducing engine noise transmission into the cabin and shielding nearby plastic or electrical parts from excessive engine heat. Unlike generic insulation, its OE-specific shape and cutouts perfectly align with Volvo’s engine bay layout, ensuring seamless integration with factory components (e.g., engine cover fasteners, wiring harnesses) and preserving the vehicle’s original engineering standards.


Core Functions

  • Acoustic Dampening: The multi-layered composite absorbs and blocks high-frequency engine noise (e.g., valve train rattle, intake/exhaust hum) and low-frequency vibration, reducing cabin noise levels by 3–5 dB (decibels) on average. This creates a quieter, more comfortable driving experience—especially at idle or highway speeds.
  • Heat Insulation: Acts as a thermal barrier between the hot engine and the engine cover, cabin firewall, or nearby components (e.g., plastic air ducts, electrical sensors). It reduces heat radiated upward from the engine, preventing overheating of sensitive parts and minimizing heat transfer into the cabin (enhancing HVAC efficiency in warm weather).
  • Engine Bay Protection: The outer protective layer resists oil, coolant, and road debris, preventing stains or degradation of the insulation material. It also shields the insulation’s internal layers from wear caused by engine vibration or minor contact with other bay components.
  • Seamless Fitment: Manufactured to Volvo’s original dimensional tolerances, it features pre-cut holes and notches for easy alignment with factory mounting points. No trimming or modification is required, ensuring a tool-friendly installation that matches the vehicle’s original assembly quality.



Compatible Vehicles

This sound absorber/engine cover insulation board (OE: 31298731) is specifically tailored for Volvo’s premium sedan, wagon, and crossover models, with confirmed compatibility for the following consolidated variants and years:

Model Applicable Years
Volvo S80 (07-) 2007–2016
Volvo S80L 2009–2015
Volvo XC70 (08-) 2008–2016
Volvo V70 (08-) 2008–2016


Notes: “S80 (07-)” denotes S80 models launched from 2007 onward; “XC70 (08-)” and “V70 (08-)” refer to variants introduced in 2008+. For 100% fitment accuracy, confirm compatibility with your vehicle’s VIN (Vehicle Identification Number) or Volvo’s official service manual—this accounts for regional trim levels and engine-specific configurations.



Frequently Asked Questions (FAQ)


Q1: How to determine if the thermostat is faulty?

A1: A thermostat failure usually causes the following symptoms:

Engine overheating: The thermostat is stuck in the closed state, preventing the coolant from entering the radiator.

Slow engine heating: The thermostat is stuck in the open state, and the coolant is always circulating, causing the engine to be unable to reach normal operating temperature for a long time.

Increased fuel consumption: The engine does not work at the optimal temperature, the combustion efficiency will be reduced, resulting in increased fuel consumption.


Q2: What should be paid attention to when replacing the LR062498 thermostat?

A2: It is recommended to be replaced by a professional technician, and pay attention to the following points:

Operate when the engine is cold to prevent burns.

Drain the old coolant correctly.

Make sure the seal is installed in place during installation to prevent coolant leakage.

After replacement, the cooling system needs to be vented to prevent "air blockage" from affecting the cooling effect.
