GM Parts introduced the next generation of Duraguard® oil filters in May 2005.
According to customer feedback, the new filter design is harder to install in blind applications(fig. 15). To eliminate installation concerns, a locator plate is being added to the oil filter lid(fig. 16).


The new locator plate design (flat surface) allows for easier installation in blind applications with no effect to the filter's performance. A rolling change will begin January 27, 2006, with no part number revisions. The first part numbers to be implemented are the 25011520 (PF53) and 19114118 (PF53F).
