Detailed Description

This Pioneer Cables PE-139 engine expansion plug kit is built for cylinder block applications where a steel plug is specified. The zinc-plated steel design supports corrosion resistance while maintaining the durability needed in engine rebuild and repair work. It is listed for 1978-1980 Toyota Cressida, 1979-1980 Toyota Celica, and 1992 Toyota Cressida and Supra applications. If you are sourcing an engine expansion plug kit for a Toyota Cressida, Toyota Supra, or Toyota Celica, PE-139 provides a direct fitment reference for those model years.

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

Common Repair Uses

• Replacing a corroded or damaged engine expansion plug during rebuild
• Restoring cylinder block sealing after freeze plug service
• Addressing coolant leakage from worn block plugs
• Supporting engine teardown and reassembly on Toyota Cressida, Supra, or Celica models

Installation Notes and Tips

Verify the block opening size and plug style before installation. Clean the bore thoroughly, inspect for pitting or distortion, and install the plug squarely to ensure proper seating. Confirm vehicle application by year and model before ordering PE-139.
