Review on 🔧 Genuine GM 12639250 Crankshaft Oil Seal Housing, Rear - Premium Quality for Optimum Engine Performance by Corey Listner

This product fits 2005 Chevy Avalanche with 5.3L Flex Fuel and requires no special tools to center the housing around the crankshaft to ensure proper alignment to ensure alignment. To install, apply a small amount of light oil to the crankshaft and carefully slide the housing over the gasket. Rotate carefully and reinstall, making sure the gasket is properly seated on the crankshaft. to block body. Since no alignment tool is used, you don't want to force the housing left, right, up, or down to deform the oil seal so it's no longer perfectly centered on the crankshaft. The body will center naturally as long as you slowly and steadily pull the body against the block. When the housing is fully seated on the block, tighten to the manufacturer's recommended torque and tightening pattern.
