Brand: Volvo Penta
Official Product Type: By-Pass Oil Filter – Spin-On Canister
System: Engine Lubrication
Supersedes: 21632901
Overview
The Volvo Penta 22030852 is the genuine OEM by-pass oil filter for Volvo Penta D4 and D6 marine diesel engines. It works alongside the primary oil filter (22030848) to provide a second stage of fine filtration, removing contaminants that pass through the primary filter and helping protect internal bearings, journals, and lubricated engine components over time.
This is not the primary oil filter — D4 and D6 engines use both filters as part of a complete oil service. Replacing only one filter leaves the lubrication system partially serviced.

Serial Number & Fitment Notice
Confirm your exact engine model and serial number before ordering. D4 and D6 engines use both a primary oil filter and a separate by-pass filter. 22030852 is the by-pass filter — it is not the same as primary filter 22030848. Both are required for a complete oil service on these engines.
Superseded Part Numbers
- 21632901 — previous Volvo Penta part number, superseded by 22030852
- 22030852 — current OEM part number
Dimensions & Weight
Approximate weight: 0.4 kg. Spin-on canister design. Exact filter dimensions (thread size, height, bypass pressure rating) are not published in current Volvo Penta accessory literature — confirm by part number match to your engine’s service documentation.
Service Interval
Replace the by-pass oil filter at every scheduled engine oil and filter service interval, or as required by the applicable Volvo Penta maintenance schedule. Regular replacement maintains clean lubricating oil and protects internal engine components. Always replace both the by-pass filter (22030852) and the primary filter (22030848) at the same service.
Installation Notes
Remove the old spin-on filter and clean the filter mounting surface. Lightly lubricate the new filter gasket with clean engine oil before installation. Torque to the specification in the applicable Volvo Penta service manual. After starting the engine and establishing oil pressure, check the filter base for leaks before returning the vessel to service.

Technical FAQ
Q: What is the difference between 22030852 and 22030848?
A: On D4 and D6 engines, these two filters perform different roles. 22030848 is the primary oil filter; 22030852 is the by-pass oil filter. Both are required for a complete oil service — replacing only one leaves the lubrication system partially serviced.
Q: Does 22030852 replace 21632901?
A: Yes. 22030852 is the current Volvo Penta OEM part number that supersedes the earlier 21632901.
Q: Can I use an aftermarket by-pass filter?
A: Volvo Penta recommends genuine OEM filters for marine engines. Aftermarket filters may not match the bypass pressure rating or media efficiency required for the D4/D6 lubrication system.
Q: How do I confirm this is the right filter for my engine?
A: Match by engine model and serial number using the Volvo Penta parts diagram. If you are unsure, contact us with your engine serial number and we can confirm the correct parts for a complete service.
Parts Desk Insights
The most common issue with this part is customers ordering only one filter when D4 and D6 engines actually require two — the primary filter (22030848) and this by-pass filter (22030852). If a customer is doing a full oil service, make sure both filters are in the order. Also note that 22030852 supersedes the older 21632901, so customers referencing the older number should be updated to the current part.
