Serial Number Fitment Notice
Fitment can vary by cooler arrangement, engine version, and production break. Confirm Volvo Penta 838928 against your exact engine serial number before ordering to ensure the correct plug for your application. Volvo Penta's official parts guidance specifically advises identifying the engine, shield, or drive when selecting parts.
When This Part Needs Replacement
Replace this plug when the original part is corroded, damaged, leaking, seized, or removed during oil cooler service and no longer provides a dependable seal. It is also a smart replacement item when servicing surrounding oil cooler components on older engines where corrosion or thread wear is common.
Installation Notes
Confirm the exact application by serial number before installation. Inspect the plug threads and sealing surfaces, and follow the correct Volvo Penta service procedure for the specific engine and oil cooler assembly being serviced. Because this part appears across many engine families, matching by serial number is more reliable than ordering by model family alone.
Alternate/Superseded Part Numbers
Current sources reviewed consistently present 838928 as the active Volvo Penta ordering number for this plug. The cleanest genuine ordering reference remains Volvo Penta 838928.
Parts Desk Insight
Small oil-cooler plugs like this are easy to overlook, but they matter when you are trying to prevent repeat leaks after cooler service. On older Volvo Penta diesel families especially, replacing worn plugs during cooler work can save time and help avoid rework once the system is back together. Serial-number verification is the safest route because this same plug shows up across a very broad span of Volvo Penta engine platforms.
