Detailed Description

Dorman 904-815 is built for Volvo vehicles that need a vacuum pump reseal rather than a full pump replacement. The kit is engineered to match original equipment fit and performance, using quality materials selected for sealing reliability and consistent operation. It is a practical service solution for Volvo S60, V60, XC60, S80, XC70, XC90, and V70 models within the listed year ranges.

What It Helps Address

• Vacuum pump oil seepage at the gasket or seal surfaces
• Loss of vacuum from worn O-rings or sealing rings
• Vacuum pump housing leaks after service or disassembly
• Reduced brake booster vacuum caused by pump sealing failure
• Vacuum system performance issues tied to deteriorated pump seals

Installation Notes and Tips

Clean all mating surfaces thoroughly before assembly and inspect the pump housing for wear, scoring, or damage. Verify O-ring placement and seal orientation during reassembly, and torque fasteners evenly to help maintain a uniform seal. Confirm the vehicle application against the listed Volvo fitment before installation.

Quality Assurance

Dorman states that this repair kit has been thoroughly tested for quality and is made to match original equipment fit and performance. The components are built to support a proper reseal of the engine vacuum pump on the specified Volvo applications.
