Detailed Description

Pioneer Cables 604004 is an OE-style engine mount engineered for the front upper mounting location on the Volvo S80 and Volvo XC90. The mount housing is manufactured from durable metal with corrosion protection or cast aluminum, then bonded with an application-specific rubber compound to help isolate engine vibration and maintain proper support.

What It Helps Address

• Excess engine vibration felt through the chassis
• Clunking or movement from a worn front upper mount
• Engine shifting under load or during acceleration
• Noise caused by deteriorated rubber isolation
• Fitment issues when replacing a damaged Volvo S80 or XC90 mount

Installation Notes and Tips

Verify the front upper mount location before installation and confirm the vehicle year and model match the listed fitment. Inspect adjacent mounts and brackets for wear or damage, since a worn support component can affect mount performance. Use the vehicle-specific fitment data for 1999-2005 Volvo S80 and 2003-2005 Volvo XC90 applications.
