Troubleshooting & FAQ
How do I confirm this kit will fit my specific Volvo Penta engine?
This kit is designed for a wide range of 40, 41, 42, and 43 series engines. The best way to confirm fitment is to check your engine model against the compatibility list provided and verify that your existing part number matches one of the cross-references (876794, 876544, 3809412).
What are the signs of a failing circulation pump?
Common symptoms include the engine overheating at idle or low speeds, coolant leakage from the pump's weep hole, a grinding or squealing noise from the pump area, and visible play or wobble in the pump pulley.
How often should a circulation pump be repaired or replaced?
There is no fixed interval; replacement depends on usage and operating conditions. It's recommended to inspect the pump for leaks or bearing play during routine annual service and replace the impeller and seals as a preventative measure every few years or if any signs of wear appear.
Does this repair kit include the main pump housing?
No, this is a repair kit containing the internal wear components (like seals, bearings, and impeller). It is designed to rebuild your existing pump housing. If your housing is cracked or severely corroded, you will need to replace the entire pump assembly.
Is any special tool required for installation?
Standard mechanic's tools are generally sufficient. However, a bearing press or puller may be helpful for safely removing and installing the bearings without damaging the housing.
What is the difference between an OEM and an aftermarket kit?
This is an aftermarket part, not sourced from the original engine manufacturer. It's designed to meet or exceed OEM specifications for fit, function, and material quality, offering a reliable and cost-effective alternative. Our parts are made in ISO 9002-certified facilities and undergo batch inspection.
How fast is shipping?
We offer fast global shipping, with most orders arriving in 5–15 days under our free standard shipping option. Expedited shipping may be available at checkout depending on your location.
What is the warranty and return policy?
This product is backed by a 1-year warranty covering manufacturing defects under normal marine use. If you encounter an issue, please contact our support team. We accept returns for unused items in their original packaging within our standard return period. Please see our full policy page for details.
