Product Details

The Bosch Workshop Oil Filter line is built around practical engine protection and service consistency. Part number 72245WS uses cellulose paper filtration media to trap contaminants before they circulate through the engine, while the anti-drain back valve helps keep oil in the filter during shutdown for quicker oil pressure on restart. The bypass relief valve adds another layer of flow control when the filter media becomes restricted. This makes the Bosch 72245WS a direct-fit oil filter choice for many Chevrolet Silverado 2500 HD and GMC Sierra 3500 HD diesel and gas truck applications, along with select Chevrolet Express, GMC Savana, and Hummer H1 models.

This part cross-references common oil filter applications such as AC Delco PF2232 and Fram PH3980 for the same application.

What It Helps Address

• Dirty engine oil carrying soot, dust, and other contaminants
• Premature engine wear caused by poor filtration
• Oil drain-back after shutdown that can delay pressure buildup
• Restricted oil flow from a loaded filter element
• Service issues on Chevrolet Silverado 2500 HD, GMC Sierra 3500 HD, and related applications

Installation Notes and Tips

Verify the 13/16-16 thread size, filter height, and outside diameter before installation.
