Detailed Description

The PE-137-R expansion plug kit is part of Pioneer Cables’ engine sealing program for rebuilders and repair shops. This steel plug option is made from fine-grained, cold-rolled steel and finished with zinc plating to help resist corrosion in demanding engine environments. It is a practical choice for cylinder block service on applications such as Buick LeSabre, Chevrolet Camaro, Oldsmobile Cutlass, and Pontiac Firebird.

This part cross-references Dorman (e.g., 555-100, 555-101) for the same application.

Common Uses

• Replacing a leaking or corroded engine expansion plug
• Restoring cylinder block sealing during engine rebuilds
• Addressing coolant loss caused by worn block plugs
• Servicing GM engines in Buick, Chevrolet, Oldsmobile, and Pontiac models

Installation Notes and Tips

Clean the block bore thoroughly before installation and inspect the sealing surface for pitting or damage. Verify the plug size and application against the engine block before assembly. For best results, install during engine rebuild or cooling system service when access to the cylinder block is open.
