Troubleshooting & FAQ
How do I know if this belt fits my Volvo Penta engine?
The surest way is to match the part number. This belt replaces Volvo Penta 3586326, 3889124, and 3817287. You can also check the compatibility table on this page to see if your specific engine model is listed.
What are the signs of a failing serpentine belt?
Common symptoms include loud squealing from the engine bay, visible cracks or fraying on the belt surface, accessories losing power, or the engine overheating due to a malfunctioning water pump.
How often should a marine serpentine belt be replaced?
There is no fixed interval, but regular inspection is key. We recommend checking the belt for wear, glazing, or cracks at least once per season or every 100 hours of operation. Replace it proactively if any signs of wear are found.
Is a special tool required for installation?
In most cases, you will need a standard ratchet or a dedicated serpentine belt tool with a long handle to release the spring-loaded tensioner. This allows you to easily remove the old belt and install the new one.

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
