Description

When your engine’s freeze plugs fail, you’ll know it pretty quick—coolant puddles under the tractor and that telltale sweet smell of antifreeze in the air. These plugs sit in the engine block to protect it from cracking if coolant freezes, and they also seal off the casting holes from manufacturing. A leaky freeze plug might seem minor, but it’ll drain your cooling system and leave you stranded in the field.

What You’re Getting

1-1/2 inch diameter frost plugs that fit standard engine block casting holes
Quality steel construction that expands properly when coolant freezes
Set of 10 plugs so you’ve got spares for future repairs or multiple engines
Universal design fits most tractor brands and heavy equipment engines
Direct replacement for worn or corroded original plugs

Built for Real Farm Work

These freeze plugs work in just about any tractor or piece of farm equipment with the right size casting holes. From older utility tractors to modern row-crop machines, diesel engines rely on these simple but critical seals to keep the cooling system intact and protect the block from freeze damage during those cold winter months in the shop.

Made to Last

Farm engines work hard in all kinds of weather, and these plugs are built to handle the temperature swings and corrosive effects of different coolant mixes. The steel construction resists corrosion better than cheaper alternatives, and they’ll expand properly if your coolant ever freezes without cracking your expensive engine block.

Installation Notes

Replacing freeze plugs takes a bit of patience—you’ll need to drain the cooling system and sometimes remove other components to get access. A freeze plug installer tool makes the job much easier than trying to drive them in with a hammer and punch. Clean the casting hole thoroughly before installation and use a light coat of sealant around the edge for the best seal.
