Detailed Description

Pioneer Cables PE-846 is an engine expansion plug kit used in cylinder block service where a 1-1/2" block plug is required. It supports a broad range of Ford, Lincoln, and Mercury vehicles, including Ford F-150, Mustang, E-150, Expedition, and Crown Victoria, along with Lincoln Town Car and Mercury Grand Marquis applications. The Pioneer expansion plug program is offered in multiple material types, giving technicians the option to match plug construction to the engine’s service needs and corrosion exposure.

This part number, PE-846, is a practical choice for engine rebuilders working on block plug replacement during teardown, overhaul, or cooling-system repair. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Coolant leaks from worn or corroded block plugs

Installation Notes and Tips

Verify block plug diameter before installation and confirm the engine uses a 1-1/2" plug opening. Clean the bore thoroughly, inspect for corrosion or pitting, and follow standard engine assembly procedures for plug seating and sealing. Confirm vehicle application by year, make, and model before ordering PE-846.
