Product Details

SKF 12718 is an engine timing cover seal engineered to help retain engine lubricant at the timing cover interface while helping block dirt and other contaminants from entering the engine. SKF has a long history in seal development, and this seal is manufactured to specific design requirements using premium materials selected for the application and operating environment. It is a practical replacement choice for vehicles such as Toyota Corolla, Toyota Celica, Toyota MR2, Toyota Tercel, Geo Prizm, and Chevrolet Nova when the listed fitment matches the vehicle.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
