LowPricedAutoParts Brass Freeze Plug Kit (Expansion/Core Plugs) - Fits Ford Lincoln Mercury 351 400 OHV V8 Engines 1970-1982

Prevent coolant leaks and protect your Ford 351 or 400 V8 from freeze-related damage with this premium brass freeze plug kit from LowPricedAutoParts – a complete set tailored for the 5.8L/351 and 6.6L/400 OHV V8 engines (naturally aspirated applications; Cleveland or Modified variants; GAS) from 1970–1982. This high-quality kit fits classic models like Bronco, F-100/F-150/F-250/F-350, Mustang, Torino, Thunderbird, E-Series vans, and more – essential for engine rebuilds, refreshes, or replacing worn/corroded plugs in these torque-heavy big-blocks that powered muscle cars, full-size sedans, and heavy-duty trucks with strong low-end power and durability. 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 steel for dependable coolant containment and protection against cracking in cold weather or harsh conditions. Matched to the 351/400 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 revive your vehicle's legendary grunt, smooth operation, and classic performance for years of enjoyable cruising, towing, or restoration projects. 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 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.
