Detailed Description

Pioneer Cables PE-120 is an engine expansion plug kit intended for cylinder block sealing service during engine repair or rebuild. The steel plug design uses cold-rolled, fine-grained construction and a zinc-plated finish to help resist corrosion in demanding engine environments. This part number is listed for Cadillac Commercial Chassis, Fleetwood, DeVille, Eldorado, and Seville applications across the 1968-1984 model years. PE-120 is a practical choice when replacing worn or corroded block plugs on Cadillac engines.

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

What It Is Used For

• Replacing leaking or rusted engine block expansion plugs
• Restoring cylinder block sealing during engine rebuilds
• Addressing coolant loss caused by deteriorated plugs
• Servicing Cadillac engines with original-style steel expansion plugs
• Supporting corrosion-resistant repair in engine block openings

Installation Notes and Tips

Clean the block bore thoroughly before installation and inspect the sealing surface for pitting, scale, or distortion. Verify the correct plug style and diameter for the specific engine block opening before assembly. For Cadillac DeVille, Eldorado, Fleetwood, Seville, and Commercial Chassis service, match the plug to the engine application listed in the catalog and follow standard engine rebuild procedures.

Quality Assurance

Pioneer Cables supplies expansion plugs in multiple materials for engine service, including steel, stainless steel, and brass, with steel versions selected for strength and zinc-plated corrosion resistance. PE-120 follows that product approach for engine block repair work.
