LowPricedAutoParts Brass Freeze Plug Kit (Expansion/Core Plugs) - Fits Ford Mercury FE Series 352 360 361 389 390 391 427 428 Engines 1958-1978

Shield your classic Ford FE engine from coolant leaks and freeze-related damage with this premium brass freeze plug kit from LowPricedAutoParts – a complete set designed for the legendary FE series V8s from 1958–1978, covering 5.8L/352, 5.9L/360-361, 6.3L/389, 6.4L/390-391, 7.0L/427, and 7.0L/428 (naturally aspirated applications). This high-quality kit fits iconic models like Bronco, F-Series trucks (F-100 to F-350), Mustang, Galaxie, Fairlane, Thunderbird, Torino, Cougar, Ranchero, E-Series vans, and more – essential for engine rebuilds, refreshes, or replacing corroded/worn plugs in these big-block powerhouses that defined Ford's muscle and truck era with massive low-end torque and durability. The kit supplies all required 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 climates or harsh environments. Matched to the FE family's bore specs (4.000"–4.233"), these plugs provide a precise, factory-style fit that reduces leak risks, maintains cooling efficiency, and promotes long-term engine reliability. Perfect for addressing age-related deterioration during overhauls – this set helps revive your Ford's legendary performance and keeps it running strong with efficient cooling for years of enjoyable driving or heavy-duty use. This is not a universal kit for non-FE engines or heavily damaged blocks without inspection – professional measurement of plug holes (often ~1.75" standard on FE), thorough cleaning, and correct installation (with sealants as per Ford guidelines) are key for a perfect, leak-free seal without warping. Always double-check hole diameters and seating during assembly. Verify your exact year and application before ordering.
