Detailed Description

Pioneer Cables 830004 is part of a complete expansion plug program that includes brass, steel, stainless steel, and threaded styles. This brass version is selected where corrosion resistance is a priority, making it a practical choice for engine rebuilds and cooling-system related block service. It is listed for applications such as 1968-1973 Ford Mustang, 1977-1981 Ford Thunderbird, and 1979-1991 Mercury Grand Marquis, along with additional Ford, Mercury, and Lincoln models through 1995.

Use Pioneer Cables 830004 when servicing cylinder block openings on vehicles that require a brass expansion plug. The part number 830004 is a direct catalog reference for rebuilders and technicians working on Ford Mustang, Mercury Cougar, and Lincoln Town Car applications.

What It Helps Fix

• Corrosion at engine block plug locations
• Leaking or deteriorated freeze plug openings
• Block service needs during engine rebuilds
• Replacement of worn brass expansion plugs in cooling-system service
• Fitment matching for classic Ford, Mercury, and Lincoln engine work

Installation Notes and Tips

Verify the block opening size and application before installation. Clean the bore thoroughly, inspect for pitting or damage, and confirm the plug seats evenly in the cylinder block. Because fitment varies by engine and model year, match the vehicle listing carefully before ordering. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
