Application Details

This Pioneer Cables PE-105 expansion plug kit is used during engine rebuilds and cylinder block service where worn or corroded plugs need replacement. Pioneer’s expansion plug program includes steel, brass, stainless steel, and threaded styles, and this steel version uses a zinc-plated finish to help resist corrosion in demanding engine environments. It is a practical choice for restoring sealing integrity in classic Ford Mustang, Ford Bronco, and Mercury Capri engine work.

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

What It Helps Fix

• Coolant leaks from deteriorated engine block plugs
• Corrosion around original steel expansion plugs
• Seepage found during engine teardown or rebuild
• Service issues on older Ford and Mercury cylinder blocks
• Replacement needs for restoration and maintenance work

Installation Notes and Tips

Inspect the block bores carefully before installation and clean away rust, scale, and old sealant. Verify the plug style and diameter against the engine block opening before pressing or driving the plug into place. For best results, follow the service procedure for the specific Ford or Mercury engine being repaired.

Quality Assurance

Pioneer Cables supplies expansion plugs in multiple materials for engine rebuilders, with steel versions made from cold-rolled steel and zinc plated for corrosion resistance. PE-105 is a service part intended for rebuild and maintenance use across listed Ford and Mercury applications.
