Description
When you see that telltale puddle of coolant under your tractor or catch a whiff of antifreeze in the cab, there’s a good chance one of your engine block plugs has given up the fight. These little plugs might look insignificant, but they’re what keep your coolant where it belongs—inside the engine instead of pooled on the ground. A failed freeze plug can turn a productive day into an expensive breakdown if you don’t catch it quick.
What You’re Getting
- Corrosion-resistant construction that handles constant temperature swings and pressure cycles without deteriorating
- Precision sizing for a snug, leak-free fit in your New Holland engine block
- Built to handle the extreme temperature cycles farm engines face—from freezing morning startups to hours of heavy work in summer heat
- Direct replacement that installs without modifications or special tools
Built for Real Farm Work
This freeze plug is designed specifically for New Holland T5, T6, and T7 series tractors that handle everything from utility work around the barn to heavy field operations. Whether you’re running a T5 on loader duty, pulling implements with a T6, or tackling big jobs with a T7, this plug keeps your cooling system sealed tight so your engine runs at proper operating temperature.
Made to Last
Engine blocks deal with constant heating and cooling cycles, vibration, and whatever coolant chemistry you’re running. This freeze plug is engineered to handle all that without corroding through or working loose. The materials resist the galvanic corrosion that eats cheaper plugs, giving you reliable service season after season.
Installation Notes
Installing freeze 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. Clean the bore thoroughly first, and don’t forget to check your coolant level after the repair.
