Troubleshooting & FAQ
How do I confirm this pump fits my engine?
This pump is designed for Volvo Penta AQ series and Volvo B230 automotive engines. The most reliable method is to cross-reference your old part number with those listed in our Part Number Matrix. Additionally, please compare the product photos against your existing part before purchasing.
What are the signs of a failing water pump?
Common symptoms include coolant leaks originating from the front of the engine, a grinding or whining noise from the pump area, a wobbly pulley, or the engine consistently running hotter than normal or overheating.
Can I replace just the water pump without changing the timing belt?
While you can, it is highly recommended to replace the water pump and timing belt at the same time. The water pump is often driven by the timing belt, and accessing it requires significant labor that overlaps with a timing belt job. Replacing both prevents having to do the same job twice if one fails after the other.
Is this pump compatible with both square and round tooth timing belts?
Yes, this water pump kit is confirmed to be compatible with engine configurations using either square tooth (typically 1985-1992) or round tooth (1993 and newer) timing belts.

This listing is for an aftermarket replacement, not an OEM component.

Our parts are produced in an ISO 9002-certified facility and are batch-inspected for quality and consistency.
How fast do you ship and what are the costs?
We ship worldwide quickly, with typical transit times of 5–15 days for most regions. Standard shipping is free on all orders. If expedited shipping options are available for your location, they will be presented at checkout.
