EGR Cooler to Up Pipe Gasket, LLY LBZ Duramax | 2006-2007

This gasket seals the joint between the EGR cooler and the exhaust up pipe on the 6.6L Duramax in 2006 and early 2007 Classic Chevrolet Silverado and GMC Sierra 2500HD and 3500 trucks with the LLY or LBZ, and in 2006-2007 Express and Savana vans. GM lists it as the EGR valve cooler gasket, part number 97372002. Ours is made by MAHLE and replaces GM 97372002. A leak at this joint is an exhaust leak, which can show up as an exhaust smell under the hood and soot around the connection.

Key Features

• Replaces GM 97372002
• MAHLE part number G33847
• About 110 x 70 mm, 0.4 mm thick, two bolt holes on 82 mm centers

Benefits

Exhaust gaskets are crushed when they're torqued and don't reseal once they come apart. Install a new one any time the EGR cooler, up pipe or turbo is removed, so you don't have to go back in for a leak. Replace if worn or damaged.
