Description
Nothing ruins a good day faster than finding coolant under your tractor or seeing that telltale green puddle in the barn. When frost plugs start weeping or blowing out completely, it’s not just a mess—it’s a sign your cooling system can’t do its job properly. This 41.27mm frost plug seals up that hole in your Major’s engine block and keeps your cooling system where it belongs.
What You’re Getting

- Steel construction that handles thermal expansion and contraction cycles
- Cup-style design that creates a secure mechanical seal when properly installed
- Direct replacement that doesn’t require engine modifications or special tools
Built for Real Farm Work
This frost plug is designed specifically for Ford Major tractors—those reliable workhorses from the 1940s and 50s that are still earning their keep on farms today. Whether your Major is pulling a plow, running a hay baler, or powering the PTO on a sawmill, it needs a cooling system that holds pressure and keeps operating temperatures in the safe zone.
Made to Last
Frost plugs might look simple, but they serve a critical purpose in your engine’s cooling system. This one’s built from quality steel that can handle the constant heating and cooling cycles your tractor goes through. The material expands and contracts with the block, maintaining a tight seal even after years of temperature swings.
Installation Notes
Installation is straightforward with the right technique—drive it in square and seat it evenly around the circumference. Clean the bore thoroughly and check for any cracks or damage before installing the new plug. A light coating of sealer around the edge helps ensure a watertight fit.
