Product Details

Pioneer Cables PE-172-R is part of a broad expansion plug program that includes steel, stainless steel, brass, and threaded styles for engine rebuilding needs. This steel version uses fine-grained, cold-rolled steel with zinc plating to help resist corrosion in demanding cooling-system environments. It is a direct service part for Chevrolet Chevette and Pontiac Acadian engine block applications listed below, making PE-172-R a practical choice for block repair and restoration work.

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