Volvo/Renault Oil Water Separator cup 20875073

OE Ref.: 20875073

Application: Volvo truck

Description: The oil-water separation cup, sometimes also called the oil-water separator bowl or simply the water separator cup, is a component designed to collect and store water and contaminants separated from the engine oil. This is particularly important in diesel engines to prevent water-related engine issues.

How often need to change oil-water separation cup in Volvo Trucks?

Draining Frequency:

For many heavy-duty trucks, including Volvos, the oil-water separation cup should be checked and drained regularly, potentially at every service interval. Depending on the truck’s use and the operating environment, this might be every 10,000 to 15,000 kilometers. Well, this maybe a difference, however, so it’s essential to monitor the situation.

Replacement Interval:

The actual replacement of the separation cup might be less frequent. Typically, unless there’s visible damage or wear to the cup/bowl, you might only need to replace it every 60,000 to 80,000 kilometers (or 40,000 to 50,000 miles). Again, the specifics can vary based on the model of the truck and the conditions it’s subjected to.

Driving Conditions:

Trucks operating in high-humidity or rainy environments might require more frequent checks and potential replacements. Water and contaminants can accumulate faster under these conditions.

Visible Inspection:

Over time, the cup may develop cracks, get damaged, or show signs of wear. A visual inspection can help determine if a replacement is needed outside of the regular schedule.

Owner’s Manual Reference:

It’s crucial to consult the Volvo truck’s owner’s or service manual for specific guidelines regarding the maintenance and replacement intervals of the oil-water separator cup and associated components.

To summarize, the separation cup should be checked and drained regularly, but the need for actual replacement is based on condition and wear, and typically less frequent. Always ensure to keep up with regular maintenance schedules and, if in doubt, consult a professional technician for guidance.
