LowPricedAutoParts Brass Freeze Plug Kit (Expansion/Core Plugs) - Fits Ford International 6.8L 6.9L 7.3L IDI & Power Stroke Diesel V8 Engines 1983-2003

Prevent coolant leaks and protect your Ford or International diesel V8 from freeze-related damage with this premium brass freeze plug kit from LowPricedAutoParts – a complete set tailored for the 6.8L/420, 6.9L/420, and 7.3L/445 OHV V8 diesel engines (naturally aspirated or turbocharged applications; 6.9L IDI and early Power Stroke designations; DIESEL) from 1983–2003. This high-quality kit fits heavy-duty models like E-Series Econoline vans (E-250/E-350/E-450), Excursion, F-150/F-250/F-350 Super Duty, Cargostar, Metro II, and more – essential for engine rebuilds, refreshes, or replacing worn/corroded plugs in these legendary diesels that powered work trucks, tow rigs, and fleet vehicles with unmatched durability, massive torque, and proven longevity. The kit supplies all necessary premium brass freeze plugs (also known as core plugs or expansion plugs) to seal block and head casting holes, offering superior corrosion resistance over standard steel for dependable coolant containment and protection against cracking in cold weather or extreme conditions. Matched to the 6.8L/6.9L/7.3L diesel specs, these plugs deliver a precise, OEM-style fit that minimizes leak risks, maintains cooling system pressure, and promotes long-term engine health. Ideal for addressing age-related failures during overhauls – this set helps keep your truck or van running strong with restored efficiency, raw pulling power, and heavy-duty reliability for towing, hauling, fleet work, or off-road duty. This is not a universal kit for mismatched engines or severely damaged blocks without inspection – professional measurement of plug holes, thorough cleaning, and correct installation techniques (with sealants as per Ford/International guidelines) are crucial for a leak-free, distortion-free seal. Always verify hole diameters and drive plugs squarely during assembly. Verify your exact year and application before ordering.
