" smaller, redesigned Original Equipment (OE) oil filter is now in production that offers ACDelco's exclusive Duraguard® media protection.
The new filter applications (GM part numbers 19210283, 19210284, 19210285, and 19210286) are installed as original equipment in applicable new GM models. While performing oil changes on several 2010 GM models equipped with the new filter, such as the Chevrolet Colorado and GMC Canyon, technicians may notice the smaller size of the filter compared to the old design.
The new oil filter features ACDelco's Duraguard synthetic cellulose-blended media that efficiently filters particles as small as 25 microns -- 1/3 the width of a human hair -- to ensure a clean supply of oil to engine components. (Fig. 5, A) It also has a full cover baseplate for easy installation in blind applications (Fig. 5, B), a new nylon core that provides better flow characteristics and improved collapse strength (Fig. 5, C), and a combination relief and anti-drainback valve that prevents dry starts and assures oil flow (where applicable).
