Post Cooling System Bypass Elbows for SII 3800 Engines

When replacing the tensioner assembly or removing it to do a lower intake manifold (LIM) gasket job the two coolant elbows most likely will not remove intact so replacement will be necessary. Pics show broken elbows and new GM/Delco replacement elbows along with the latest GM part numbers.

Top of pic - Elbow to lower intake manifold (LIM) - GM Part # 24503423
Bottom of pic - Elbow to water pump - GM Part # 12565082
