GM Oil Pan Baffle Windage Tray, Duramax LML LGH | 2010-2016

The oil pan baffle, GM part number 12627246, is the factory steel windage tray that mounts in the oil sump on the 6.6L LML and LGH Duramax. GM calls it the engine oil sump windage tray. It fits 2011-2016 Chevrolet Silverado and GMC Sierra 2500HD and 3500HD trucks and 2010-2016 Chevrolet Express and GMC Savana 2500, 3500 and 4500 vans. The baffle controls oil slosh and keeps the oil around the pump pickup when the vehicle accelerates, brakes, turns or climbs grades. It also helps separate the oil from the spinning crankshaft. A damaged, bent or missing baffle can let the pickup draw air, causing low or flickering oil pressure. Replace it when the original is damaged or when you service the pan or pump.
