The crankshaft seal is a critical component in your vehicle's engine, responsible for maintaining a seal around the rotating crankshaft. Its primary function is to prevent engine oil from leaking out of the crankcase and to keep contaminants from entering the engine. A failing crankshaft seal can lead to significant oil loss, potentially causing engine damage if not addressed promptly. This specific seal, part number 12010743B from CORTECO, is engineered for precise fitment and reliable sealing.
