Description
When you see coolant puddles under your tractor or notice rusty water marks around the engine block, there’s a good chance one of your frost plugs has failed. These little steel discs keep coolant in and corrosion out, but they’re also designed to pop out if the cooling system freezes—saving your engine block from cracking. This 10-pack of 1-inch frost plugs gives you enough spares to fix the problem and keep a few on hand for the next time.
What You’re Getting
- Ten high-quality 1-inch (25.78mm) frost plugs for reliable engine sealing
- Universal fit design works across most tractor makes and models
- Steel construction that handles engine heat and cooling system pressure
- Convenient 10-pack quantity so you’ll have spares when you need them
Built for Real Farm Work
These frost plugs fit just about any tractor engine with 1-inch freeze plug holes. From compact utility tractors to big row-crop machines, most engines use these standard-size plugs in the engine block and cylinder heads. They’re essential for keeping your cooling system sealed while protecting the engine from freeze damage during cold weather.
Made to Last
These plugs are built from quality steel that resists corrosion and handles the constant expansion and contraction that comes with engine heating and cooling cycles. They’re designed to seal tight under normal operating conditions but will safely release pressure if the cooling system freezes, potentially saving you thousands in engine repairs.
Installation Notes
Installing a frost plug takes the right technique—you’ll need to drive it into the block square and seated properly. Clean the hole thoroughly first, then use a socket or frost plug installer to seat it evenly. A light coating of sealant around the edge helps ensure a leak-free fit. If you’re dealing with a frozen-out plug, it’s smart to check your coolant mixture to prevent it from happening again.
