Description
Nothing ruins your day quite like seeing coolant pooling under your tractor or watching steam pour out from under the hood. When a frost plug gives up, you’ve got minutes to shut down before serious engine damage occurs. This 1-inch frost plug is your insurance against coolant leaks and freeze damage—a simple part that does a critical job of keeping your cooling system sealed tight. With this convenient 10-pack, you’ll have spares on hand when you need them.

Built for Real Farm Work
These frost plugs work in engines across the Ford New Holland lineup, from compact utility tractors handling daily chores to big row-crop machines pulling through long field days. These little metal plugs seal the casting holes left from engine manufacturing, but years of freeze-thaw cycles, vibration, and coolant chemicals eventually take their toll. When you’re running equipment hard in all kinds of weather, having reliable plugs keeps coolant where it belongs.
Made to Last
Stainless steel construction means these plugs won’t corrode like regular steel versions. This frost plug is built to handle all that without corroding through or working loose. The metal composition resists the galvanic corrosion that eats cheaper plugs, and the sizing ensures a snug fit that won’t leak. They’re designed to handle the pressure changes and temperature swings that come with hard farm work.
Installation Notes
You’ll need to drain the cooling system for installation, so it’s a good time to replace multiple plugs if others look questionable. Clean the bore thoroughly before pressing in the new plug—any debris or corrosion will prevent a proper seal. Installing frost plugs requires tapping them into place with the right technique – drive them in straight and square, not cocked sideways. A block of wood and a hammer works better than trying to use a punch that might push through.
