The Crankshaft Seal is a part and parcel of GMC Acadia automobiles, which is installed at the front side of the engine so that the engine oil kept in the crankcase does not seep out. Usually made out of metal with adherence to rubber this round seal is of paramount importance in feeding special lubricant for these engine parts in order to reduce friction and thus increase durability of the engine. In the course of the operational time, it is possible to notice that the crankshaft seal is worn out or damaged, which can cause an oil leak and other complications. One can diagnose a faulty crankshaft seal through signs that should be attended to as soon as possible, particularly if the car is old or with high mileage, so that the engine will operate correctly. It is also important for the reader to know that even though the location of the crankshaft seal is virtually the same across all model years, minor differences in the design materials or construction may be observed between a newer and older model year, however, the function of the crankshaft seal stays the same.
