Description

Help keep engine oil sealed in at the nose of the crankshaft with the National Crankshaft Seal 710551. This front seal is a direct-fit replacement for many vehicles, among them the 2004-2012 Chevrolet Colorado 2.8L / 2.9L / 3.5L / 3.7L, the 2004-2012 GMC Canyon 2.8L / 2.9L / 3.5L / 3.7L and the 2002-2009 Chevrolet Trailblazer 4.2L; see the "Vehicles it fits" section for the full list.

A front crankshaft seal sits where the crankshaft exits the front of the engine. The seal body stays stationary, and its sealing lip contacts the rotating crankshaft to help hold engine oil inside. Over time a seal can wear, and oil can begin to seep past it. Signs this engine crankshaft seal may need replacing include oil seepage or drips at the front of the engine and oily residue on nearby components. Other gaskets in the same area can leak too, so pinpoint the source before you replace any part.

Position: front crankshaft seal.
Engines: L4-2.8L, L4-2.9L, L5-3.5L, L5-3.7L and L6-4.2L.
