Key Features

• Brass construction for strong corrosion resistance
• Engine expansion plug kit for cylinder block components

Product Details

Pioneer Cables PE-186-BR is part of Pioneer’s expansion plug program, which includes brass, steel, stainless steel, and threaded options for engine service. This brass version uses solid brass material to provide corrosion resistance in demanding cooling-system environments. It is a practical choice for engine rebuilders and technicians servicing classic Chrysler, Dodge Ram 50, Dodge Colt, and Plymouth applications.

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

What It Helps Address

• Coolant leaks caused by worn or corroded block plugs
• Seepage around aging engine expansion plugs
• Service issues during engine rebuilds and block refurbishment
• Replacement needs on older Chrysler, Dodge, and Plymouth engines

Installation Notes and Tips

Clean the block bore thoroughly before installation and inspect the sealing surface for pitting or debris. Verify the plug style and diameter against the original engine block opening before assembly. For best results, install during engine service when the cooling system is drained and the block is accessible.

Quality Assurance

Pioneer offers expansion plugs in multiple materials for different service requirements, including brass for corrosion resistance, steel for strength, and stainless steel for added corrosion protection where needed by the application.
