Troubleshooting & FAQ
How do I confirm this kit fits my specific engine?
Verify your engine model matches those listed in the "Engine & Model Compatibility" table. This kit is made for specific Volvo Penta MD5, MD6, and MD7 series engines and fits water pump housings 833883 and 840076. Always cross-reference the part number (875584) with your engine's service manual.
What are the signs my water pump needs to be rebuilt?
Common signs of pump failure include visible water leaks from the pump seals (weep holes), a cracked or brittle impeller, consistent engine overheating alarms, or reduced water flow from the exhaust.
How often should I service the water pump?
It is best practice to inspect your water pump impeller at least once per season or every 100 hours of operation. A full rebuild is recommended every few hundred hours or immediately if you notice signs of wear, leaks, or damage.
What is included in this repair kit?
This kit contains the necessary aftermarket components to complete a standard rebuild, designed to be equivalent to the OEM kit (875584/875584-5). This typically includes seals, gaskets, and other wear items.
Can I use this for a Volvo Penta MD11C?
While some sources suggest compatibility with the MD11C, it is not consistently documented. We strongly recommend verifying the part number on your existing pump or in your engine's service manual. This kit is a confirmed fit for pumps 833883 and 840076.
