BULLETIN ACD09-154
DATE: September 2009
TO: All ACDelco Distributors
SUBJECT: FILTER DESIGN CHANGE – PF46, PF47, PF52 AND PF61
Description
ACDelco is implementing a design change on the PF46, PF47, PF52 and PF61 ACDelco Oil Filters due to capacity constraints on the current product design. GM engineers have approved the new design which will begin to be incorporated in upcoming vehicle designs. This OE approved and manufactured filter provides the same Duraguard filtration performance as the previous design and specifically utilizes the original ACDelco media that traps particles down to 25 microns. Additional features include a slightly smaller can, fully covered baseplate, non-metallic end caps and high strength nylon core. This newly designed oil filter has the benefits of not only bringing excellent filtration performance, it is also environmentally friendly with components that can now be easily separated into steel, oil and parts to incinerate, resulting in less waste.
The Durapack versions of the newer design filter have begun shipping. The boxed or individually packaged versions will utilize the available production capacity on the original design, where possible, and will then begin to rollover to the newer design.
