Help keep engine oil sealed in and dirt shut out at the back of the crank with the Timken crankshaft seal, part number 5291, a rear-position grease/oil seal built around a precision sealing design. It fits many vehicles, among them the 2005-2009 Buick LaCrosse V6-3.8L, the 1991-2005 Buick LeSabre V6-3.8L and the 1968-1973 Buick Riviera V8-7.0L or V8-7.5L. See the Buyer's Guide tab for the full list of applications.
Precision sealing design: intended to keep lubricant from escaping and stop harmful contaminants from getting in, with an internal contamination exclusion system that helps keep out debris that may lead to leakage.
Reinforced outer case: helps guard against damage during installation and adds durability.
Ribbed rubber inner diameter: designed to seal over minor surface imperfections and promote positive seating.
Vent holes: let lubricant flow freely around the seal lip, cooling the seal components and carrying away heat build-up.
This engine crankshaft seal serves the rear position. The seal body stays stationary while its lip rides on the turning crankshaft. Signs it may need replacing include oil seeping from the rear of the engine, oil residue where the engine meets the transmission, or fresh drips under the vehicle after it sits. Other gaskets and seals nearby can leak in the same area, so confirm the leak source before replacing the seal.
