Benefits

A hardened or flattened sensor seal can weep oil around the crankshaft position sensor. Since the seal is inexpensive, it makes sense to replace it any time the sensor comes out. Replace if worn or damaged. Merchant Automotive also carries the Crankshaft Position Sensor, Duramax | 2006 - 2010 and the Crankshaft Position Sensor, Duramax | 2010 - 2016.
