When This Kit May Be Needed

• The original valve is worn, damaged, or has lost its shape
• The vacuum pump does not work consistently after internal wear
• There is an air leak, poor sealing, oil leakage, or loose fit
• The pump has been disassembled and requires a new repair valve
• Vacuum system performance is unstable or weaker than normal

What This Kit Does

The vacuum pump supports systems that rely on vacuum pressure, including brake assist and other vacuum-operated components depending on the vehicle configuration. A worn or leaking valve inside the pump can reduce sealing efficiency and cause unstable vacuum performance.

This repair kit helps restore the valve sealing area of the original pump and can be a practical repair option when the pump housing and seating surfaces are still in usable condition.

Repair Notes

• Inspect the vacuum pump housing before installation
• Check the seating surface for wear, cracks, or deformation
• Clean the pump carefully before fitting the repair part
• If the pump body is badly worn or damaged, the complete pump may need replacement

Why Choose This Repair Kit

• Allows repair of the original vacuum pump valve area
• Helps avoid replacing the complete pump when only the valve is worn
• Designed for pumps with references 31258031 and 31375107
• Helps restore sealing and stable vacuum pump operation
• Suitable for professional repair or experienced DIY service

Important Before Ordering

Please compare the number on your original vacuum pump or valve with the listed references before ordering. Vehicle model alone is not enough to confirm compatibility, because the same Volvo model may use different vacuum pump versions depending on engine, year, market, and equipment.

Also confirm that the issue is related to the vacuum pump valve itself, not the pump housing, vacuum lines, brake booster, sensors, wiring, or other components in the vacuum system.

FAQ

How do I check compatibility?
Compare the number on your original vacuum pump or valve with the reference numbers in this listing: 31430964, 31258031, or 31375107.

Why should I not choose only by vehicle model?
The same Volvo model can be equipped with different vacuum pump versions depending on the engine, year, market, and vehicle configuration.

Is this a complete vacuum pump?
No. This is a repair kit for the vacuum pump valve area. It is not a complete vacuum pump assembly.

What should be checked during repair?
Check the pump housing, seating surfaces, signs of oil leakage, and vacuum performance. If the housing is damaged or heavily worn, the complete pump may need to be replaced.

What if my part number does not match?
Do not order by guesswork. Check the original part number, pump marking, VIN information, or compare the old part visually before purchasing.
