Detailed Description

MotoRad MO331 is an engine oil filter cap engineered as a direct-fit service part for Volvo models across multiple years, including XC90, S80, and S60 applications. The round cap measures approximately 3.40 inches at the head, with a 3.44-inch thread diameter, and is built from OEM-approved materials to meet or exceed OEM quality standards. This part cross-references Dorman - OE Solutions 917-017 for the same application.

For Volvo XC70, V70, C70, S40, and V40 service work, the MO331 provides a specific replacement option where the original cap uses a screw-on design and a sealing gasket. The black cap body and molded indicator markings support straightforward identification during maintenance. The MO331 part number is also useful when verifying the correct oil filter cap before ordering.

What It Helps Solve

• Cracked or worn oil filter cap housing
• Damaged sealing surface at the filter cap
• Oil seepage caused by a degraded rubber seal
• Incorrect cap fitment on Volvo filter housing service
• Missing or unreadable indicator markings on the cap

Installation Notes and Tips

Confirm the existing cap uses a screw-on design and match the thread diameter and overall dimensions before installation. Inspect the sealing surface and replace any damaged gasket interface during service. Verify fitment by vehicle year, model, and engine oil filter housing configuration before ordering the MO331.
