Product Details

Pioneer Cables PE-216 is part of a broader expansion plug program that includes steel, brass, stainless steel, and threaded styles.

It is a direct-fit service part for cylinder block component repair on Mitsubishi Mighty Max, Mitsubishi Montero, Mitsubishi Starion, and Mazda B2600 applications listed in the fitment data. PE-216 is a practical choice for engine rebuilders and technicians replacing worn or leaking block plugs during cooling system service.

Common Repair Uses

Installation Notes and Tips

Inspect the plug bore carefully before installation and clean away rust, scale, and old sealant residue. Verify the replacement plug matches the application before pressing or seating it into place. For best results, follow the engine service procedure for the specific Mitsubishi or Mazda model and confirm the cooling system is properly filled and pressure-tested after repair.
